Local plasticity rules can learn deep representations using self-supervised contrastive predictions
Learning in the brain is poorly understood and learning rules that respect biological
constraints, yet yield deep hierarchical representations, are still unknown. Here, we propose …

Novelty is not surprise: Human exploratory and adaptive behavior in sequential decision-making
Classic reinforcement learning (RL) theories cannot explain human behavior in the absence
of external reward or when the environment changes. Here, we employ a deep sequential …
