Check out Jonny's latest work on a bio-plausible synaptic learning rule that yield interesting properties in artificial neural networks! It was very exciting and fun to contribute to this work.

Why does #compneuro need new learning methods? ANN models are usually trained with Gradient Descent (GD), which violates biological realities like Dale’s law and log-normal weights. Here we describe a superior learning algorithm for comp neuro: Exponentiated Gradients (EG)! 1/12

Interesting thread on convergence (or lack thereof) of neural solutions, with cool refs in the replies.

It seems a lot of studies focus on classification rather than control tasks, and oft simple input dynamics. I'm looking forward to seeing this further explored in the future.

Is there a name for the hypothesis that task-trained neural networks and biological brains develop similar representations when they perform well, despite differences in architecture and learning methods? I.e. that optimization (whether backprop or evolution) leads to a similar solution?

If not, I think we should call it The Tolstoy Hypothesis: "All well-functioning networks are alike; each poorly functioning network is poor in its own way."

Thank you to the @wusmsl for providing a great platform to exchange ideas and discuss science in-depth! Always a pleasure to interact with the folks down there, I warmly recommend
No video this time around but @wusmsl was lucky to have lab alum @OlivierCodol present his recent work: "Brain-like neural dynamics for behavioral control develop through reinforcement learning". Check it out, definitely some food for thought! doi.org/10.1101/2024.1…
