Brainy Breakdown: 5/26/2017

DeepMind’s AlphaGo achieves superhuman performance, becoming “the god of the Go game” A surprisingly reasonable discussion about the singularity. Note that they don’t use the word. Related: AI can be overhyped. On the positive side, Sebastian Thrun on the power of AI. Privacy concerns who? Google takes on AutoML to try to automate the myriad...
Paper Review: An Integration of Deep Learning and Neuroscience, Part 3

Paper Review: An Integration of Deep Learning and Neuroscience, Part 3

In our previous post we talked about how the brain might optimize cost functions. Now we’ll explore how cost functions may be generated, represented, and change over time in the brain. Marblestone et al outline several ways that cost functions could be generated.  In particular, they talk about specialized circuitry for comparing the predicted output...

Paper Review: An Integration of Deep Learning and Neuroscience, Part 2

One of the key sticking points in discussions comparing machine learning and the brain is how the notion of “learning” differs between computational and biological systems. In section 2 of their paper, Marblestone et al. grapple with this issue in detail. For our introduction post on this paper, go here. Deep neural networks are trained...

Paper Review: An Integration of Deep Learning and Neuroscience, Part 1

Nicole: More and more I see that people are very concerned with the biological plausibility of neural networks. I think this comes from the fact that we as machine learners are finally achieving human-level performance on some tasks. It has renewed faith in the idea that the best way to “solve” intelligence is to copy...

Neuroscience news: what’s fake and what’s real?

Reporters have gotten very, very good at writing catchy headlines.  With all of the clickbait floating around the internet, the news has become an arms race, and science news is no exception.  Since people like hearing about how their brains work, and everyone secretly (not so secretly?) likes reading about sex, drugs and rock and...
Trump's War on Science

Trump’s War on Science

Donald Trump has been president for just over a week, but he’s wasted no time making his agenda clear.  The administration has made its agenda clear with a set of discriminatory executive orders, the blatant denial of facts, and talk of alternative facts, Brainy is a science blog, and so we feel it is our...
