Summary
The paper introduces Drift-Diffusion Matching, a framework for training recurrent neural networks (RNNs) to model complex stochastic dynamics in low-dimensional spaces, emphasizing the role of asymmetric connectivity in enhancing network behavior.
Why It Matters
This research provides insights into how RNNs can better emulate biological neural networks, which often exhibit asymmetric connectivity.

In contrast, biological networks support rich time-dependent behaviour facilitated by their asymmetry. Here we introduce a general framework, which we term drift-diffusion matching, for training continuous-time RNNs to represent arbitrary stochastic dynamical systems within a low-dimensional latent subspace. Allowing asymmetric connectivity, we show that RNNs can faithfully embed the drift and diffusion of a given stochastic differential equation, including nonlinear and nonequilibrium dynamics such as chaotic attractors. As an application, we construct RNN realisations of stochastic systems that transiently explore various attractors through both input-driven switching and autonomous...
