New neural network uses local plasticity for source separation

Researchers have developed a new neural network approach called Predictive Entropy Maximization for blind source separation. This method utilizes local weight updates and is inspired by biological dendritic computation and plasticity. It achieves competitive performance by approximating an entropy measure, outperforming algorithms relying on stronger independence assumptions and remaining robust against noise and source correlation.

    Normative Networks for Source Separation via Local Plasticity and Dendritic Computation

    Blind source separation (BSS) is a natural framework for studying how latent causes may be recovered from sensory mixtures, but deriving online and biologically plausible algorithms for structured (i.e., constrained to known domains) and potentially correlated sources remains cha…
