Unconditional stability of a recurrent neural circuit implementing divisive normalization

NeurIPS 2024poster

Stability in recurrent neural models poses a significant challenge, particularly in developing biologically plausible neurodynamical models that can be seamlessly trained. Traditional cortical circuit models are notoriously difficult to train due to expansive nonlinearities in the dynamical system,…

Adaptive Whitening in Neural Populations with Gain-modulating Interneurons

ICML 2023poster

Statistical whitening transformations play a fundamental role in many computational systems, and may also play an important role in biological sensory systems. Existing neural circuit models of adaptive whitening operate by modifying synaptic interactions; however, such modifications would seem both…
