Can we rule out near-term AGI? [video]
- simonh 8y agoHe says general AI is on the same spectrum as the AI technologies we have now, but is qualitatively different. I'm sorry but that's a contradiction. If it's on the same spectrum, then it's just a quantitative measure of where on the spectrum it lies. If it's qualitatively different, it's on another axis, another quality is in play. His definition is also rubbish. Being useful at economically valuable work has nothing necessarily to do with intelligence. Writing implements are vital in pretty much all economic activities, many couldn't be done at all without them before keyboards came along. Deep Learning is great, it's a revolution, but it's a fairly narrow technology. It solves one type of task fantastically well, it just happens that solving this task is applicable in many different problem domains, but it's still only one technique. At no point did he show how to draw a line from Deep Learning to General AI in any recognisable form. It just looks like a hook to get you to hear his pitch. It's a great pitch, but it's not about AGI.
- wycs 8y ago>He says general AI is on the same spectrum as the AI technologies we have now, but is qualitatively different. No it is not. The basic premise of fixed-winged aircraft was the same from Wright brothers to modern jets. Yet the wright brothers flyer was useless and a modern jet is not. We have agents that can act in environments. His claim is that getting these agents to human-level intelligence is a matter of compute and architectural advancements that are not qualitatively different that what we have now. This just does not strike me as an absurd claim. We have systems that can learn reasonably robustly. We should accord significant probability to the claim that higher-level reasoning and perception can be learned with these same tools given enough computing power. He claims we cannot "rule out" near-term AGI. Let's define "rule out" as having a probability of 1% or lower. I think he's given pretty good reasons to up our probability to between 2-10%. For myself, 10-20% seems a reasonable range.
- spuz 8y ago> No it is not. What claim are you responding to here? Simonh said: > He says general AI is on the same spectrum as the AI technologies we have now, but is qualitatively different. I'm sorry but that's a contradiction. Which I agree with. How can two qualitatively different things be on the same spectrum? You later say yourself: > His claim is that getting these agents to human-level intelligence is a matter of compute and architectural advancements that are not qualitatively different that what we have now. Which seems to be the opposite of what simonh said and it's confusing to say the least.
- wycs 8y agoYou are right. I don't think I read his comment very carefully before replying.

- oliveshell 8y agoI’m not too convinced by this guy’s argument: as evidence, he presents the progress made by deep learning/CNNs in the past few years. He then rightly acknowledges the difficulty of getting machines to do abstraction and reasoning, noting that we have ideas about how to approach these things but that they require much more computing power than we have now. ...Then he basically asserts that we can extrapolate the near-term availability of tons more compute power from Moore’s Law, which is where he lost me. We’re already running into the limits of physical law in trying to move semiconductor fabrication to smaller and smaller processes, and there are very real and interesting challenges to be overcome before, I think, we can resume anything close to the exponential growth we’ve enjoyed over the last 40 years. This guy may well think a lot about these difficulties, but not mentioning them at all made his argument sound incredibly naïve to me.
- wycs 8y ago>...Then he basically asserts that we can extrapolate the near-term availability of tons more compute power from Moore’s Law, which is where he lost me. That's not what he's asserting. Even with Moore's law dead, OpenAI claims there is significant room with ASICs, analog computing, and simply throwing more money at the problem. There is a ton of low-hanging fruit in Non-Von Neumann architectures. We should expect it to be plucked, as we have huge use case which is potentially limitlessly profitable.
- simonh 8y agoThat's how I take it as well, as I said in another comment it is a compelling pitch. And yes he's not talking about Moore's Law, but how much compute is actually being dedicated to DLNN's simply because the value of doing so is going up so fast.
- foobiekr 8y agoThe video boils down to “more compute => AGI.” It’s silly and specious.
- iotb 8y agoAccelerating the efficiency of an optimization algorithm doesn't get you AGI, this should be clear by now. As for fielding such systems, one quick way to destroy humanity to a degree is to turn everything into a glorified optimization problem which will no doubt be turned against people to maximize profit.
- deleted 8y ago[deleted]
- mckoss 8y agoIt does seem he is conflating "progress" with "investment". Yes, the world is spending exponentially more compute each year since 2012 on training networks. The marvel is that neural architectures are scaling to more complex problems without much architectural change. But this is not an argument that AI is getting more efficient or productive over time and hence we can expect exponential performance improvements (like Moore's law).
- emtel 8y agoI think a lot of people who are emphatic that AGI is a long way off are saying so out of an allergic reaction to the hype, rather than due to sound reasoning. (And let me be clear that none of this is an argument that AGI is near. I'm saying that confidence that it is far is unfounded.) First, there are many cases in science where experts were totally blindsided by breakthroughs. The discovery of controlled fission is probably the most famous example. This shouldn't be surprising - the reason that a breakthrough is a breakthrough is because it adds fundamentally new knowledge. You could only have predicted the breakthrough if you somehow knew that this unknown knowledge was there, waiting to be found. But if you knew that, you'd probably be the one to make the breakthrough in the first place. Second, most claims about the impossibility of near-term AGI are totally unscientific. By that, I mean that they aren't based on a successful theory of falsifiable predictions. What we'd want, in order to have any confidence, is a theory that can make testable predictions about what will and won't happen in the short term. Then, if those predictions turn out to be true, we can gain confidence in the theory. But this isn't what we get. What we get is people saying "We have no idea how to do x, y, and z, therefore it won't happen in the next 50 years". I don't see any evidence that people were able to predict even the incremental progress we've seen say, two years out. The fact is that when someone says "it'll take 50 years" that's just sort of a gut feeling, and people will almost certainly be making that same prediction the year before it actually happens. Third, I think people have too narrow a view about what they imagine AGI might look like. People tend to envision something like HAL, that passes Turing tests, can explain chains of reasoning, and has comprehensible motivations. Let's consider the case of abstract reasoning, which is something thought to be very difficult. We tried and failed for decades to build vision systems based on methods of abstract reasoning, e.g. "detect edges, compose edges into shapes, build a set of spatial relationships between those shapes, etc". But humans don't use abstract methods in their visual cortex, they use something a lot more like a DNN. The mistake is in thinking that because the mechanism of successful machine vision resembles human vision, therefore the mechanism of successful machine reasoning must resemble human reasoning. But its quite possible that we'll simply train a DNN by brute force to evaluate causal relationships by "magic", i.e. in a way that doesn't show any evidence of the sort of step-by-step reasoning humans use. You can already see this happening - when a human learns to play breakout, they start by forming an abstract conception of the causal relationships in the game. This allows a human to learn really really fast. But with a DNN, we just brute force it. It never develops what we would consider "understanding" of the game, it just _wins_. Sorry the third point was so long, let me summarize: We think some things are hard because we don't know how to do them the way that we think humans do them. But that doesn't serve as evidence that there isn't an easy way to do them that is just waiting to be discovered.
- tomiplaz 8y agoThe talk's title has very little to do with the actual talk. The talk is about progress in narrow AI in the last 6 years or so. While fascinating, it's still only progress in narrow AI. To make artificial intelligence general, one would have to somehow define a fitness function that itself is general. But how does one do that? How does one say to a machine: "Go out there and do whatever you think is most valuable"? If some kind of goal has to be defined, it seems it will always be a narrow AI, where some outside entity defines what its goal is, instead of itself coming to a conclusion what it should do in general sense. Even if that machine is able to recognize the instrumental goals for reaching the final goal (and acting accordingly), it still feels like a non-general intelligence, like connecting the dots based on the available input and processing, just to come closer to that final goal. If no final goal was given, I presume such a machine would do nothing: it would not randomly inspect the environment around itself and contemplate upon it; there would be no curiosity, no actions of any kind to find out anything about its environment and set its own goals based on observation. It seems that for AGI to come, some kind of spontaneous emergence would have to occur, possibly by coming up with some revolutionary algorithm for information processing implemented inside an extremely capable computer (something that biological evolution has already yielded). It is interesting, humbling and a bit depressing to apply the same reasoning to us, humans. We are relatively limited in terms of reason, its just that it is not obvious to us, just like it is not obvious that the Earth is round, for example.
- tlb 8y agoHaving novel, unique goals is not necessary for AGI. Normal people don't have novel goals -- they mostly want love, comfort, and respect. An AGI that had as its goal "gain people's respect" would exhibit an unboundedly interesting range of behavior.
- visarga 8y agoWell said. Humans (and all living things) have the same ultimate goal: life. They need to keep themselves alive somehow and keep their genes alive by reproduction. That single goal has blossomed into what we are today. If we train AI with an evolutionary algorithm, and let it fend for its needs (compute, repair, energy), then it could learn the will to life that we have, because all variants that don't have it will be quickly selected out of existence. I think AGI could happen with today technology if we only knew the priors nature found with its multi-billion year search. We already know some of these priors: in vision, spatial translation and rotation invariance, in temporal domain (speech) it is time translation invariance, in reasoning it is permutation invariance (if you represent the objects and their relations in another order, the conclusion should be unchanged). With such priors we got to where we are today in AI. Need a few more to reach human level.
- gugagore 8y agoI think what I found most lacking in this video is that data did not play a role in the overview. The presenter discusses that a ton of computation is needed to do deep learning, but doesn't explain why. And really, it's because the models are big and the training data is even bigger. So computation improves, and helps you deal with bigger models and bigger data, but where does the data come from? The big question to me isn't whether computation can scale, which this video makes me belief it will. It's whether the data will scale. In RL domains with good simulators, such as Go and the Atari games, data doesn't seem to be an issue. The in-hand robot manipulation work also makes heavy use of simulators to reduce the amount of real-world time needed to collect data. But I don't see an argument that we will need to get high-fidelity simulators to train these agents in. I do love the in-hand robot manipulation work, because it's one of the few that shows that results from simulation can be applied to real robotic systems. And while I hope for the sake of robotics that we can get better and better simulators, it's surprising to not see that as the central focus in conversation about getting AGI to emerge from gradient descent on neural networks.
- gdb 8y ago(I gave the talk.) We are already starting to see the nature of data changing. Unsupervised learning is starting to work — see https://blog.openai.com/language-unsupervised/ https://blog.openai.com/language-unsupervised/ which learns from 7,000 books and then sets state-of-the-art across almost all relevant NLP datasets. With reinforcement learning, as you point out, you turn simulator compute into data. So even with today's models, it seems that the data bottleneck is much less significant than even two years ago. The harder bottleneck is transfer. In most cases, we train a model on one domain at a time, and it can't use that knowledge for a new related task. To scale to the real world, we'll need to construct models that have "world knowledge" and are able to apply it to new situations. Fortunately, we have lots of ideas about how this might work (e.g. using generative models to learn a world model, or applying energy-based models like https://blog.openai.com/learning-concepts-with-energy-functions/ https://blog.openai.com/learning-concepts-with-energy-functi...). The main limitation right now: the ideas are very computationally expensive. So we'll need engineers and researchers to help us to continue scaling our supercomputing clusters and build working systems to test our ideas.
- tim333 8y ago>Can we rule out near-term AGI? In keeping Betteridge's law, no, not really. Hardware capabilities are getting there as evidenced by computers trashing us at go and the like and with thousands [0] of the best and brightest going into AI research who's to know when someone is going to find working algorithms?

- zackmorris 8y agoNot sure why you're getting down voted for this since I was going to say the same thing. My feeling is that AGI is 10 years away, certainly no more than 20. That's coming from a pure computing power and modeling perspective, for example just by putting an AI in a simulated environment and letting it brute force the search space of what we're requesting of it with 10,000 times more computing power than anything today. Finding a way for an AI to focus its attention at each level of its capability tree in order to recruit learned abilities, and then replay scenarios multiple times before attempting something in real life, are some of the few remaining hurdles and not particularly challenging IMHO. The real problem though (as I see it) is that the vast majority of the best and brightest minds in our society get lost to the demands of daily living. I've likely lost any shot I had at contributing in areas that will advance the state of the art since I graduated college 20 years ago. I think I'm hardly the exception. Without some kind of exit, winning the internet lottery basically like Elon Musk, we'll all likely see AGI come to be sometime in our lifetimes but without having had a hand in it. And that worries me, because if only the winners make AI, it will come into being without the human experience of losing. I sense dark times looming, should AI become self-aware in a world that still has hierarchy, that still subverts the dignity of others for personal gain. I think a prerequisite to AGI that helps humanity is for us to get past our artificial scarcity view of reality. We might need something a little more like Star Trek where we're free of money and minutia, where self-actualization is a human right.
- iotb 8y agoEntrenched mindsets don't like for the flaws in their views to be highlighted. It's one of Humanity's most serious flaws. As far as AGI being 10-20 years away based purely on compute power, you can't make this statement accurately unless you have a firm understanding of the underlying algorithms that power human intelligence and by extension AGI. From there, you also need to have a formal education and deep industry experience with Hardware to know what its capabilities are today, what they will be in the future roadmap wise, and how to most efficiently map an AGI algorithm to them. I'd say that 0.1% of people have this understanding and nobody is listening to them. > The real problem though (as I see it) is that the vast majority of the best and brightest minds in our society get lost to the demands of daily living. I've likely lost any shot I had at contributing in areas that will advance the state of the art since I graduated college 20 years ago. I think I'm hardly the exception. Without some kind of exit, winning the internet lottery basically like Elon Musk, we'll all likely see AGI come to be sometime in our lifetimes but without having had a hand in it. They don't get lost so much as they become trapped for reasons due to systematic and flawed optimization structures found throughout society. All is not lost if one breaks out long enough to realize they can make certain pursuits if they are willing to make a sacrifice. The bigger the pursuit, the bigger the required sacrifice. Not many people are willing to do that in the valley when you have a quarter of a million dollar paycheck staring you in the face. You could of course make a decision to sacrifice everything one given day and you'd have 5 years of runway easily if you saved your money properly. Obviously, VC capital wont fund you. Obviously universities aren't the way to go given the obsession with Weak AI. Obviously no AI group will hire you unless you have a PhD and/or are obsessed with Weak AI. Obviously you might not even want this as it will cloud your mind. So, clearly, the way to make ground breaking progress is to walk off your job, fund a stretch of research yourself, and be willing to sacrifice everything. Quite the sacrifice? People will laugh at you. What happens if you fail? Socially, per the mainstream trend, you'll fall behind. If you have a partner, this will be even more difficult as the trend is to get rich quick, get promoted to management, buy a million dollar home, have kids, stay locked in a lucrative position at a company. And what of your pride? Indeed.. And therein is the true pursuit of AGI. The winners are pushing fundamentally flawed AI techniques because it requires massive amounts of data and compute which is their primary business model. They wont succeed because they are optimizing a business model that is at the end of its cycle and not optimizing the pursuit of AGI. AGI is coming and it is completely out of the scope of the current winners. If a person desires to pursue and develop AGI, they'd have to be bold enough to sacrifice everything... It's how all of the true discoveries are made for all of time and science. Nothing has changed but for reasons due to money primarily, when the historical learning lessons are far off enough people attempt to re-tell/re-invent the wheel in their favor.. Only to be reminded : Nothing has changed. The individual discoverers change over time however for they learn from history.
- marvin 8y agoJust for posterity, to see if I was completely bonkers in 2018: I believe that it is possible to realize AGI today, using currently available hardware, if we just knew enough of the principles to create the right software. Novel computational concepts have often been demonstrated on very old hardware, with the full knowledge of the tricks required to make it work. Often, more powerful hardware was required in order to pionéer the technology, and often the proof-of-concept on older hardware is too slow and clunky to have been a compelling product. But it's often been physically possible for longer than people realize. I've never made a "long game" statement like this before, so it'll be interesting to read this comment about what I thought before in 2038 or 2048, if it still exists then.
- andbberger 8y agoI don't see how you could arrive at that conclusion with any certainty. There is a computability argument - part of your statement implies the assumption that 'AGI' is computable. I would be inclined to agree in this aspect, I think a preponderance is required before we start seriously considering that intelligence is uncomputable. After all, last time I checked the jury was still out as to whether super-Turing machines are physically realizable. So let's suppose for the sake of argument intelligence is computable. Well then in principle 'AGI' has been 'realizable' since mid-last century when we first constructed Turing machines. With the caveat that it may take the lifetime of the universe to classify an image of a cat. It is quite conceivable that, although Turing-computable, 'AGI' requires taking expectations over such large spaces that it won't really be 'realizable' until hardware improves by another few orders of magnitude.
- drcode 8y agoI think it's clear an important element of AGI simply involves traversing large search spaces: This is essentially what deep neural nets are doing with their data as they train and return classification results... and it's not unreasonable to think they can already do this with a performance on par with the human brain. The problem is that there's a lot of additional "special sauce" we're missing to turn these classification engines into AGI, and we don't have a clue if this "special sauce" is computationally intensive or not. I'm guessing the answer is "no" since the human cortex seems so uniform in structure and therefore it seems to me it is mostly involved in this rather pedestrian search part, not the "special sauce" part. (disclosure: I'm not a neuroscientist or AI researcher)
- blueadept111 8y agoYes, we can rule out near-term AGI, because we can also rule out far-term AGI, at least in the way AGI is defined in this talk. You can't isolate "economically beneficial" aspects of intelligence. Emulating human-like intelligence means emulating the primitive parts of the brain as well, including lust, fear, suspicion, hate, envy, etc... these are inseparable building blocks of human intelligence. Unless you can model those (and a lot else besides), then you don't have AGI, at least not one that can (for example) read a novel and understand what the heck is going on and why.
- visarga 8y agoI think we need to have an agent centric approach. To view the world as a game, with a purpose, and the agent as a player learning to improve its game and the understanding of the world. Interactivity with humans would be part of the game, of course, and the AI agent will learn the human values and the meaning of human actions as a byproduct of trying to predict its own future rewards and optimal actions. Just like kids.
- Florin_Andrei 8y agoIt's how I feel about it too. All the structures that provide motivation, drive, initiative - are mandatory. Those have evolved first in the natural world, for reasons that I think are semi-obvious. Complex intelligence has emerged later.
- isseu 8y agoAre lust, fear, hate requirements for intelligence? There are part of human intelligence for sure. I feel the a problem is that we don't have a good definition of intelligence.
- byteface 8y agoYes. We learn through our emotions and use them for heuristics. They are measures of pleasure/stress against access to maslows needs. This drives instincts and behaviours. Also gives us values. When I 'think' or act I use schemas but don't knowingly use a GAN or leaky Relu. I personally learn in terms of semantic logic, emotions and metaphors. My GAN is the physical world, society, the dialogical self and a theory of mind. He never mentioned amygdala or angular gryus or biomimmicking the brain or creating a society of independant machines. Which we could do but aren't even trying to my knowledge? I mean there's Sophia(a fancy puppet) but not much else. We get told to use the term .agi despite public calling it .ai as that's just automation. But this feels like we're now allowed to call it .ai again? It was presented as, given these advances in automation we can't rule out arriving at apparent consciousness. But with no line between. We do have a definition for intelligence. Applied knowledge. However here's another thought. Several times in my life I knowingly pressed self destruct. I quit a job without one to go to despite having mortgage and kids. I sold all my possessions to travel. I've dumped a girls I liked to be free. I've faced off against bigger adversaries. I've played devils advocate with my boss. I've taken drugs despite knowing the risks etc... And I benefitted somehow (maybe not in real terms) from all of them. Non of these things seem like intelligent things to do. They were not about helping the world but about self discovery and freedom. We cannot program this lack of logic. This perforating of the paper tape (electric ant). It's emergent behaviour based on the state of the world and my subjective interpretation of my place in it. Call it existential, call it experiential, call it a bucket list. Whatever. .agi would need to fail like us, to be like us. Feel an emotional response from that failure. And learn. Those feelings could be wrong. misguided. We knowingly embrace failure as anything is better than a static state. i.e people voting Trump as Hilary offered less change. We also have multiple brains. Body/Brain. Adrenaline, Seratonin. When music plays my body seems to respond before my brain intellectually engages. So we need to consider physiological as well as phsycological. We have more that 2000 emotions and feelings (based on a list of adjectives). But that probably only scratches the surface. What about 'hangry'? Then learning to recognise and regulate it. diff( current perception of world state, perception of success at creating a new desired world state (Maslow) ) = stress || pleasure. Even then how do you measure the 'success'? i.e.I have friends with depressions and they don't measure their lives by happiness alone. I feel depression is actually a normal response to a sick world and that people who aren't a bit put out are more messed up. If we created intelligence that wasn't happy, would we be satisfied? Or would we call it 'broken' and medicate like we do with people. Finally I don't think they can all learn off each other. They need to be individual. language would seem an inefficient data transer method to a machine. But we indivudate ourselves against society. Machines assimilating knowledge won't be individuals. More swarm like. We would need to use constraints which may seem counter productive so harder to realise. Wow. I wrote more than I inteded there. But yes. Emotions are required IMO. Even the bad ones. Sublimation is an important factor in intelligence.
- iotb 8y agoDid Artificial General Intelligence get redefined again towards something more short term? So, first AI is hijacked and hyped 50 ways to sunday.. Then came the apocalyptic narratives/control problem hype to secure funding for non-profit pursuits and research. Then, when it was realized that narrative couldn't go on forever. AGI was hijacked added to everyone's charter and a claim was made that it will be made 'safe'. Now, AGI's definition is getting redefined to the latest Weak AI techniques that can do impressive things on insane amounts of compute hardware. How can you ever achieve AGI if this is the framing/belief system the major apparatus of funding/work centers on? Where is the true pursuit of this problem? Where are the completely new approaches? One cannot rule out something unless they've spent a concerted amount of time dedicated solely to trying to understanding it. If there is no fundamental understanding of Human intelligene, what is anyone frankly talking about? or doing? I have yet to hear a cohesive understanding of human intelligence from various different AI groups. I have yet to hear a sound body of individuals properly frame a pursuit of AGI. So, what is everyone pursuing? There seems to be no grand vision or lead wrangling in all of these scattered add-on techniques to NN. I do see a lot of groups working on weak AI or chipping away at AGI like featuresets with AI techniques making claims about AGI. Everyone has become so obsessed with iterating that they fail to grasp the proper longer term technique for resolving a problem like AGI. Void from the discussion are conversations on Neuroscience and the scientific investigation of Intelligence. There's more sound progress being made in the public sector on concepts like AGI than in the private sector. Mainly because the public sector knows how to become entrenched, scope, and target an unproven long term goal and project. The hype as far as I see it is clearly distinguishable from the science. Without honest and sound scientific inquiries, claims in any direction are without support. Everyone's attempting to skip the science and pursue engineering in the dark with flashy public exhibitions namely because of funding.. You can't exit such a room and make sound claims about AGI. If a group claims they are pursuing AGI, I expect almost all of their work to be scientific research pursuing an understanding. That being said, it appears no one is interested in funding or backing such an endaevour. Everyone states they want to back/invest in such a group on paper but when it comes down to it the money isn't there, they obviously are targetting shorter term goals/payouts, and/or don't frankly know what type of pursuit or group of individuals are required. No one wants to take the time to understand what such a group would look like. No one wants to make a truly longer term bet. This is why things have been spiraling in circles for years. So, as it has been stated time and time again.. AGI will come and it will come from left field. There are individuals who truly care to pursue and develop AGI and they're willing to sacrifice everything to achieve it. If no funding is available, they'll fund themselves. If groups wont accept them because they aren't obssesed with deep learning or have a PhD (clearly the makeup that only results in convoluted weak AI), they'll start groups themselves. Passion + Capability + lifelong pursuit is how all of the great discoveries of time have come to us. The mainstream seemingly never understanding such individuals, supporting them, or believing them until after they've proven themselves. No pivots. No populist iterations. A fully entrenched dedication towards achieving something until its done. So, no.. you can't rule out AGI in the near term because there is no spotlight on the individuals or groups with the capability to develop it on such time horizons and the thinking just frankly isn't there in celeberated groups with funding. Everyone's in the dark and its an active choice and mindset which causes this. Geoffery Hinton says start all over.... Yann LeCun raises red flags. No one listens. No one acts. Everyone wants a piece of the company that develops the next trillion dollar 'Google' like product space centered on AGI but no one wants to spend the time to consider what such a company would be, what is human intelligence, who is looking at it in a new way from scratch as some of the most important people in AI have stated. So, you see... This is why the unexpected happen. It is unexpected because no one spends the time or resources necessary to cultivate the understanding to expect its coming.
- gambler 8y ago>"Prior to 2012, AI was a field of broken promises." I just love how these DNN researchers love to bash prior work as over-hyped, while hyping their own research through the roof. AI researchers did some amazing stuff in the 60s and 80s, considering the hardware limitations they had to work under. >"AT the core, it's just one simple idea of a neural network." Not really. First neural networks were done in the 50s. Didn't produce any particularly interesting results. Most of the results in the video are a product of fiddling with network architectures, plus throwing more and more hardware at the problem. Also, none of the architectures/algorithms used by deep learning today are more general than, say, pure MCTS. You adapt the problem to the architecture, or architecture to the problem, but the actual system does not adapt itself.
- habitue 8y agoSo, they didn't have backprop and automatic differentiation in the 50s. That's pretty fundamental and not just "fiddling with architectures"
- gambler 8y agoBut being fundamental in this context is a bad thing. It's not like there is a single "neural" architecture that's getting better and better. There are dozens of different architectures with their own optimizations, shortcuts, functions and parameters.
- Cybiote 8y agoThis statement is fairly inaccurate. If you check Peter Madderom 1966 thesis, you'll see that it states the earliest work on automatic differentiation was done in the 1950s. It's just that back then, it was called Analyitc differentiation. You can see many of the key ideas already existed back then, including research into specializations for efficiently applying the chain rule. https://academic.oup.com/comjnl/article/7/4/290/354207 https://academic.oup.com/comjnl/article/7/4/290/354207
- habitue 8y agoAh, you're right on AD. But backprop was invented in the 80s
- cvaidya1986 8y agoNope I’ll build it.
