For those interested in studying the dynamics of networks with lateral/recurrent connections, Stephen Grossberg pretty much wrote the book on mathematically analyzing these systems: http://www.scholarpedia.org/article&#

This research from Yuste's lab is really refreshing to me and probably more appealing to the HN audience than a lot of other neuroscience research. The main reason is that it focuses on how the brain carries out information processing

It's hard to tell since there's no context but one way I interpreted it is that he used to think it was mostly only the established synapses were changing. Instead, with this new result, perhaps he sees many more synapses being fo

From the article and their website, it doesn't seem like KnuEdge's compute units are spiking neurons. Spinnaker and IBM 's TruNorth using spiking neurons to compute.

The company changed names somewhat recently from Intellisis (mentioned in the article). Try searching for that.

Is Julius really state-of-the-art? Looks like they use n-gram and HMMs. Those were the methods that achieve SotA 5+ years ago. My understanding is that Google and Microsoft are using end-to-end (or nearly) neural network models; these outpe

This is HUGE in my opinion. Prior to this, in order to get near state-of-the-art speech recognition in your system/application you either had to have/hire expertise to build your own or pay Nuance a significant amount of money to

The author is wrong in stating, "yet neuroscientists have not scrutinized their brains for one simple reason: They don’t have a neocortex." Birds have an analogous structure to the mammalian neocortex [1]. [1] http://ww

I'm not sure why this comment is being down voted. This comment is spot on. As a neuroscientist reading this article I asked the same question. It is so easy in clinical research to be fooled by randomness and the placebo effect.

I believe you are mistaken. Adult neurogenesis has only been shown to occur in three brain regions as far as I know: in the hippocampus (declarative memory and learning)[1], the olfactory bulb (smell)[1] and the striatum (procedural memory

Can someone explain the rationale for leaking this? I have been a strong critic of NSA domestic surveillance, but what is described in the article seems to be the appropriate use of the U.S. intelligence apparatus.

No! Humanity has not fundamentally changed. We are still made of flesh and blood, we still have the same cognitive biases, we are still fighting religious wars, we still feel jealously, greed, fear and yearn for power. In that sense, nothin

When I talk to friends about the existential threats to our country this is the other one I think of. Terrorism doesn't even make the list. I'm totally with you on our country becoming more of an oligarchy. I think we're talk

I agree with the author wholeheartedly, except for the mathematical analysis at the end. I believe one of the existential threats to our country is becoming a dictatorship. I'm always shocked when I share this point of view with people

An interesting and early (1992) demonstration of deep nets learning latent structure in the visual domain was presented by Usui et al. They presented a deep autoencoder with the spectral values of color chips and show that the hidden layer

In one sense we did know about the capabilities of neurons, or at least made similar predictions. How all of the ingredients come together to achieve this is not understood. The computational properties of neurons are massively complex, e.g

It is surprising and comments like this always pop-up in response to comments like mine. The question is how much information do you really need to identify individuals? I can't answer that since I haven't seen the data set they a

There are good arguments to be made about your point, but I don't think this is necessarily one of them. As the article quotes, "The data is anonymous, but it allows us to see where those folks have gotten care." What Amino h

I agree and disagree. I would definitely start with a simpler algorithm like logistic regression or even trees and use temporal features like power at different frequencies by taking an FFT. I would even add time lagged features. After that

I agree with you in terms of approach that AI will emerge first from brain emulation. I disagree with you on the timeline. I know you say 'starting around 2030', but I think that's a little ambitious. While I'm an AI&#x2

I think a similar problem needs to be solved in the language generation neural networks. While generated sentences often are formed syntactically correct, they don't make a lot of sense -- there's no over arching thought that it i

How is that not a neural network? This system is basically exploiting the property of action potential propagation down the axon to capture relative timing differences. As an aside, there are a number of useful properties seen in biological

Good point about dropout. Do you know of any quantitative studies that address this specifically?

Indeed, another weakness is that multi-layer perceptrons and their deep counterparts are susceptible to "catastrophic forgetting" -- training away old memories when new training data is presented. This is one reason why it's
