arXiv:2603.26506v2 Announce Type: replace-cross Abstract: Connectivity structure shapes neural computation, but inferring this structure from population recordings is degenerate: multiple connectivity structures can generate identical dynamics. Recent work uses low-rank recurrent neural networks (lrRNNs) to infer low-dimensional latent dynamics and connectivity from observed activity, enabling a mechanistic interpretation of the dynamics. However, standard approaches for training lrRNNs can recover spurious structures irrelevant to the underlying dynamics. We first characterize the identifiabi
The continuous advancement in AI and machine learning techniques provides new avenues to understand complex biological systems like neural dynamics, pushing the boundaries of interpretability.
Improved methods for inferring neural connectivity from dynamics could significantly enhance our understanding of brain function and pathologies, impacting AI through bio-inspired computing and neuroscience research.
The ability to more accurately identify connectivity structures from neural activity using low-rank recurrent neural networks (lrRNNs) reduces spurious interpretations, offering a clearer mechanistic view of brain computation.
