1/n Excited to share our new preprint where we study turbulent plume tracking using deep reinforcement learning (DRL) trained RNN *agents* and find many intriguing similarities with flying insects. w/ @FlorisBreugel @RajeshPNRao @bingbrunton;

We've a new paper in pre-print, showing how inhibitory circuits coordinate motor behavior: https://t.co/CQImxLR60C

🦓 Self-supervised multimodal ML is promising the next AI breakthrough - in our new work published in @Nature, we debut @CEBRAai: for self-supervised hypothesis- and discovery-driven science.

How to move to Mastodon.
1. Choose a server (I know, it is hard, you don't have enough info!). I'll include a post at the end about popular servers for scientists. It's easy to move if you don't like the one you start on. Join on the page for your server.

Hope you enjoy our most recent work studying the mechanism and function of stride-based signals on Drosophila visual neurons.

Walking strides direct rapid and flexible recruitment of visual circuits for course control in Drosophila https://t.co/YolJWym0tt

Rhythmic/repetitive yet complex behaviors can be controlled by combining slow and fast rhythms - nested Central Pattern Generators. We have just published this: https://t.co/KHF7mR9Aos

Slowly but ever so surely, days are getting longer.

[California Sea Grant @CASeaGrant]

One of the major factors in preserving beaches and coastal habitat is the rather complex issue of how sediment is transported from land into the ocean, and how it moves along the coastline in a #littoralcell - for the basics on sand movement see: https://t.co/3xkzD2R2sx

[California Sea Grant @CASeaGrant]

Sea-level rise is expected to lead to the loss of up to two-thirds of SoCal beaches by 2100. To protect our beaches, California needs regional cooperation and a focus on sediment, argue experts in a recent paper:

Animals don't make decisions by using one set of decision rules - but multiple rules

How can we find those rules, when animals switch moment-to-moment? With a GLM-HMM

Mice alternate between discrete strategies

Finally my paper of last year has been made freely available to everyone (as all science should be): https://t.co/lDMEHADXFk
Much of the ML methods are out-of-date, obviously :) but for more current updates use: https://t.co/PFbxVZaBFp
