I am working on RL and robotics. I came across Levin in Lex's podcast. And then went on a binge of his other podcast appearences. I agree totally with you, I would very much like to build agents that adapt to different circumstances like "simple organisms". I am not familiar with biology, but I plan to build competence here to follow Levin's work to a point that I could potentially collabrate with biologists or learn…

I also focused on the work done by the Levin lab after the Sean Carroll podcast [1]. In order to familiarize myself with the subject matter in a more practical manner I started writing a wrapper and a frontend, BESO [2], BioElectric Simulation Orchestrator , for BETSE [3], the Bio Electric Tissue Simulation Engine developed by Alexis Pietak which is used by the Levin lab to simulate various tissues and their response…

Late to post this (found from a cross-link on another post) but just have to say, this right here is HN comment gold.

What an incredibly helpful and useful response!!

It makes a good headline, but reading over the paper ( https://www.nature.com/articles/s42256-022-00556-7.pdf ) it doesn’t seem biologically-inspired. It seems like they found a way to solve nonlinear equations in constant time via an approximation, then turned that into a neural net. More generally, I’m skeptical that biological systems will ever serve as a basis for ML nets in practice. But saying that out loud fee…

Looking at biology is what lead to CNNs the current AI boom.

Thats the whole reason we call multi layered perceptrons as "neural nets" cheesey and flashy as it is, using a sliding filter was inspired by what we know about vision im biology.

"I’m skeptical that biological systems will ever serve as a basis for ML nets in practice" First of all, ML engineers need to stop being so brainphiliacs, caring only about the 'neural networks' of the brain or brain-like systems. Lacrymaria olor has more intelligence, in terms of adapting to exploring/exploiting a given environment, than all our artificial neural networks combined and it has no neurons because it is…

I wonder if there's a step-change where single-celled animals with complex behavior are actually smarter than the simplest multiple-celled animals with a nervous system.

The cells of multi-celled animals still have complex behaviors.
