Neuroscience postdoc @ucl. Using machine learning and computational modelling to help understand memory and navigation. Very amateur footballer for @Monstars_UK

Just published in @eLife! This work was done with the amazing @neuro_kim @caswellcaswell & supremely talented co-first author @TomNotGeorge! TLDR? There's evidence hippocampus functions like a 'predictive map' - so how might this be achieved in the brain? https://t.co/cqRqapTwnz

[Malcolm Campbell @malcgcamp]

Excited to share our updated preprint on the neural basis of foraging decisions! This work was co-led by Michael Bukwich (twitterless, now at UCL) and me, with major contributions from co-authors, and the incredible animation is by @KJHerr23. (1/12)

Animals can learn to use all kinds of brain-computer interfaces, from controlling single neurons to large populations of neurons in motor ctx. How do they do this?

Thrilled to be finally sharing our research on this question, now up on biorxiv! 🧵

RatInABox🐀📦- which began accidentally from some old code I had lying around - grew to become a massive toolkit for navigational research.

It's immensely gratifying to see it finally published and being used in such a variety of ways across the field.

Cognitive models of behavior are a key part of neuroscience. But discovering them is hard!

Neural networks are powerful models. But interpreting them cognitively is hard!

We explore automatically learning interpretable models using "Disentangled RNNs"

RatInABox just passed 100 stars⭐️on Github which is a perfectly arbitrary milestone at which to announce a new feature, thanks to a contribution by community member @SynapticSage:

RiaB is now compatible with the OpenAIs “gym” API. This is big for RL users. Let me explain...🧵

Join us tomorrow, 2pm!

[Lennart Luettgau @LLuettgau]

Come see our poster (#12) at this year's UCL Neuroscience Symposium in poster session 2 (1.10-2.30 pm)! I will present our work on how humans reuse factorized and abstracted prior knowledge to compositionally generalize in novel situations.
