Finally, we highlight cases where FastDSA outperforms other dynamical similarity metrics—while remaining robust to noise.

Next, we present experiments showing why geometrical methods fail.
Both DSA and FastDSA achieve similar results—but FastDSA is 10–15× faster.

We first outline the general structure of the algorithm.

Still curious about uncovering internal state — completely unsupervised? We start in 30 minutes.

#CCN2025, Poster C160: We present MoDSA – a fully unsupervised method for identifying behaviorally relevant neural states in both biological & artificial systems.

Looking forward to seeing you there!

CMC lab @cmc-lab.bsky.social · Aug 9

An unsupervised method to find behaviorally relevant internal states from data. We tested it w/ RNN & monkey data doing cognitive tasks & RNN trained with deep RL on naturalistic plum tracking task. Visit poster C160, Fri 2-5pm, talk to @armanbehrad.bsky.social 2025.ccneuro.org/poster/?id=l...

New paper out! We show that individual dopaminergic neurons in Drosophila larvae can drive both learning and movement — two key dopamine functions. Advanced usage of Random Forest for multivariate data analysis. 🧠🪰 #Neuroscience#MachineLearning ##Dopamine#Drosophila

Individual dopaminergic neurons induce unique, yet overlapping combinations of behavioural modulations including safety learning, memory retrieval and acute locomotion
