This is a valid point and a real challenge of brain-computer interface (BCI) technology. It is largely trying to help those who suffer from locked-in syndrome, where they really do…

As stated elsewhere, this can actually be a very frustrating process. I lost a good chunk of my long weekend trying to build TF from source for CUDA 8.0 / cuDNN 5.1. Generally spea…

Reinforcement Learning is one of the most exciting areas of research in machine learning and AI going on right now in my opinion. It is going to play heavily in creating AI that ca…

Bradski is also the creator of OpenCV, an industry standard computer vision library.

IBM's TrueNorth chip is taking a much more neuromorphic design approach by trying to approximate networks of biological neurons. They are investigating a new form of computer archi…

You absolutely do not need a PhD for industry unless you want an R&D job in a handful of domains. A PhD is not simply learning more facts about a particular topic. It's an apprenti…

CaptionBot doesn't really know what to make of Winged Doom: http://imgur.com/86uwKfa

You are correct. My initial response was a pedantic point about the semantic use of monopoly in this context, which isn't helpful. I would love it if AMD would care more about GPGP…

NVIDIA does not have a monopoly in the traditional sense. But yes, the have a de facto one because there is no viable competition. It's like saying MATLAB has a monopoly in academi…

What monopoly? You totally have a choice, it's just that NVIDIA made a large bet on GPGPU and it is paying off for them. You don't see AMD heavily pushing their cards for compute p…

Only overheated once, though I rarely had them operating continuously for more than a few minutes at a time.

Ideally, yes, we want to pre-train in a virtual environment using as close to the real model robot as possible. I worked on such a problem as part of my PhD research on mobile robo…

This was totally unexpected. When I saw the Kickstarter update email in my inbox, I just assumed we were getting to jump the pre-order line. This was a great goodwill move on their…

You are correct. I worked with EEG as part of my PhD research on brain computer interfaces, and it is a super noisy signal regardless of the headset. This makes is very hard to do …

These consumer-targeted devices are predominantly used to detect and act on changes in the relative power of certain frequency bands from rhythmic neural activity. These changes in…

Very nice! I'm glad you found them useful. When I have time, I'll convert them and some unpublished examples into IPython Notebooks.

Related, a few years ago I wrote a series of blog posts with code and discussion on how to do some basic neural simulations in Python: http://www.neurdon.com/author/byron/ . This i…

> unlike forums, people really enjoy mailing lists. I don't think I've ever met anyone, ever, who said they liked forums. I think it entirely depends on what the purpose of communi…

The current state of the art for BCI ranges from 2-3 continuously valued "channels" using motor imagery (the method used in the article) or 1 channel of 2-32+ discrete choices usin…

They are using a technique called motor imagery, which looks for small changes in synchrony in the sensory motor rhythms (SMR). SMR is currently only capable of reliably detecting …

I agree with your sentiment about the lamentable, though typical HN response. However, it is totally in accordance with the mean audience of the site. Almost 50% of HN readers are …

The initial motivation for these articles - the government says we need more STEM students, but look how many underemployed PhDs there are! - is flimsy. The US does not necessarily…
