Contextually of dimension even exists within a specific scientific theory. In relativity, the direction you call time might contain some component of the direction I call space. This implies notions like simultaneity are not well defined in

It’s extremely strong almost to the point of absurdity to say that transformers are the optimal architecture. As far as we know, human minds are not transformer networks and outperform them in many respects. And it’s even absurd to me to sa

Yeah sometimes compression ratio is not the right question when there are other practical concerns like disk space or user experience. But I do want to point out that almost everyone installs at least one multigigabyte file to decompress ot

by markisus 2y ago
But we don’t usually count the decompression program size when evaluating compression ratio. Eg 7-Zip is about 1 MB, but you don’t think about that when evaluating particular 7z files.

In a way, although the double slit demonstrated self interference. In this experiment, I think the lattice is so sparsely populated that interference effects are negligible and particles move as free wave packets while the lattice is disabl

For almost all n (size), the function runs for MAX_SIZE steps, since almost all numbers are greater than MAX_SIZE. And it never runs for more than MAX_SIZE steps.

The arxiv has more details. They sparsely populated a dense lattice with particles. Then they turned off the lattice, which allowed all the particles’ wave functions to evolve according to the Schrödinger equation. Then they turned the latt

The teams started working some time around September 2023, judging by timelines shown on the website https://a2rl.io/ . This is not a lot of time and explains why the performance was so underwhelming (eg spinning out, jerkin

I’m not sure you can say that imitation learning has been under-researched in the past. Imitation learning has been tried before alongside RL. But it did not generalize well until the advent of generative diffusion models.

How does it work if there is more than one bend? Is it able to localize both bends? And what about the bend directionality? Anyway nice project. I could see it being used for a mesh to give robots a tactile skin covering.

For anyone else who is geographically challenged, the map apparently has 64 states instead of 50. Here is an article with the extra states highlighted. https://www.explainxkcd.com/wiki/index.php/2868:_Label_the_S..

This may be the status quo because of the so called "hardware lottery" which has historically been optimized for floating point. I'm speculating, but if hardware designers were instead only concerned about raw xnor density an

Your interests seem to lie closer to the systems and hardware side. Can you elaborate on why your career is in CRUD apps? What about working for SpaceX?

I’ve been using Pandas which exposes a python slicing syntax for manipulating relational data. It also has a builtin join() function. “select id, date from orders” is orders[“id”, “date”]. It’s meant for in-memory datasets but the syntax co

This quote hits close to home. “So I got the arm to match the conveyor speed by monitoring the position and pre-empting the motion command, alternating ‘slow’ and ‘fast’ at 10Hz with a duty cycle depending on how we are tracking our target.

I think PCA plus nearest neighbor was one of the earliest effective face recognition algorithms aka the eigenfaces method.

It’s funny because you really have to have a lot of experience with the language to articulate these issues. C++ is the worst language, besides all the other ones, when it comes down to performance and third party library availability. I’ll

The differential equations seem to show that this is a closed form implementation of a P (as in PID) controller. So the animation could be implemented without a call to exponential for small enough dt.

Pretty impressive. I wonder though why it was necessary to put the point map of the second image into the coordinate frame of the first. Isn’t it all the same from the point of the neural net?

From all his public talks, Carmack seems like a nice and smart guy. I’m curious why you have a negative impression.

I'm guessing this was downvoted for being rude, but I think there is a valid question here. It looks like Zed is putting a lot of work into minimizing the latency between a key being typed and feedback being displayed on a visual inter

Everything is a tradeoff. Even things like goto, and global variables will occasionally be the right choice. Regarding the std::vector method, you may have a very loosely coupled system where a bunch of T1's enter into a pipeline and c

In my example, the T is one specific type. So you could have std::vector<Cat>. If you also have Dogs, you just make another vector std::vector<Dog>. It works fine with the standard allocator. You don't have to do anything s

I usually like to place all dynamically heap objects of type T into an std::vector<T>, if possible. There is sometimes an obvious point where the entire batch should be discarded and a new batch should be built. At this point, you can

For some reason the author thinks that skills you learn developing in PyTorch will go away if Facebook does. Wouldn’t the open source community just fork the source or develop a new framework? It’s not like backprop will stop working.
