Expressive dynamics models with nonlinear injective readouts enable reliable recovery of latent features from neural activity
September 2023 • Christopher Versteeg, Andrew R. Sedler, Jonathan McCart, Chethan Pandarinath
The advent of large-scale neural recordings has enabled new methods to discover the computational mechanisms of neural circuits by understanding the rules that govern how their state evolves over time. While these \textit{neural dynamics} cannot be directly measured, they can typically be approximated by low-dimensional models in a latent space. How these models represent the mapping from latent space to neural space can affect the interpretability of the latent representation. We show that typical choices for thi…
