Adaptive RNNs develop Oscillatory Phase Coding for flexible working memory

By PulseAugur Editorial · [1 sources] ·

Researchers have developed adaptive Recurrent Neural Networks (RNNs) that spontaneously exhibit Oscillatory Phase Coding (OPC) when trained on flexible working memory tasks. This emergent property allows the RNNs to store and process information by having memorized items recur at distinct phases of a shared rhythm, with amplitude encoding item identity and phase encoding serial order. The study identified adaptation, variable delay, and flexible readout as crucial for OPC, leading to the emergence of content and time cells within the network that process identity and sequence separately.
