Sreejan Kumar @sreejan.bsky.social · 06/09/2025To test our hypothesis on the effect of sensory compression on action chunking and time coding, we developed an RNN model with sensory bottlenecks and trained it on RL tasks that involve chunking. 130 3
Sreejan Kumar @sreejan.bsky.social · 06/09/2025We show that a model with a sensory bottleneck accounts for many behavioral effects that @gershbrain.bsky.social and @lucylai.bsky.social characterize in their work on human action chunking, whereas a non-bottleneck baseline does not. 150 5
Sreejan Kumar @sreejan.bsky.social · 06/09/2025We then see that bottleneck models engage these stable neural trajectories that implicitly encode time by where you are in the trajectory. 130 3
