Researchers have identified a phenomenon in Forward-Forward networks called layer free-riding, where later layers can inherit tasks already partially handled by earlier layers, leading to a decay in gradient. Three local remedies were proposed to address this, significantly improving layer-separation statistics on CIFAR-10 and CIFAR-100 datasets without substantially altering accuracy. Separately, a new framework for variational feature compression has been developed to protect data privacy by suppressing cross-model transfer while preserving accuracy for a designated classifier. This method uses a variational latent bottleneck and a dynamic binary mask to reduce the utility of representations for unintended models. AI
