Researchers have introduced the Recurrent Divisive Normalization Network (RDNN), a novel artificial neural network model inspired by biological divisive normalization. This model is designed to overcome the limitations of traditional recurrent neural networks (RNNs) and continuous attractor networks in robustly maintaining and updating continuous variables, a key aspect of working memory. The RDNN's biophysical constraint enables it to learn high-fidelity slow manifolds, preventing the state space from fragmenting into discrete points. Additionally, the network's gradient dynamics during Backpropagation Through Time (BPTT) lead to self-compression of its effective rank, confining dynamics to a low-dimensional subspace and avoiding optimization issues.
