From spiking neuronal networks to interpretable dynamics: a diffusion-approximation framework
Modeling and interpreting the complex recurrent dynamics of neuronal spiking activity is essential to understanding how networks implement behavior and cognition. Nonlinear Hawkes process models can c...

📍Excited to share that our paper was selected as a Spotlight at #NeurIPS2025!
arxiv.org/pdf/2410.03972
It started from a question I kept running into:
When do RNNs trained on the same task converge/diverge in their solutions?

How do we make sense of scientific literature that is growing explosively to the point where no-one could read all the relevant papers, and is contaminated with fraudulent and LLM-generated papers? I think that science isn't currently equipped to deal with this, and we need to. #science #metascience

RNNs are often used to explore how the brain may solve specific tasks. We show that, depending on the architecture, RNNs find distinct circuit solutions, behaving differently when exposed to novel stimuli.

Dimensionality reduction usually loses information.
- PCA loses the non-linear cycling.
- t-SNE distorts the distances between the three populations
-- Diffusion maps compress the early state cells and lose the cycling.
