  摘要：Midbrain dopamine neurons (DANs) signal reward-prediction errors that teach recipient circuits about expected rewards1. However, DANs are thought to provide a substrate for temporal difference (TD) reinforcement learning (RL), an algorithm that learns the mean of temporally discounted expected future rewards, discarding useful information about experienced distributions of reward amounts and delays2. Here we present time-magnitude RL (TMRL), a multidimensional variant of distributional RL that...

  摘要：Modern colour image sensors face challenges in further improving sensitivity and image quality because of inherent limitations in light utilization efficiency1. A major factor contributing to these limitations is the use of passive optical filters, which absorb and dissipate a substantial amount of light, thereby reducing the efficiency of light capture2. On the contrary, active optical filtering in Foveon-type vertically stacked architectures still struggles to deliver optimal performance owi...
