Báo cáo hóa học: "Gradient estimation in dendritic reinforcement learning" potx

... NMDA-spikes can arise in certain dendritic zones. In the context of reinforcement learning, two kinds of plasticity rules are derived, zone reinforcement (ZR) and cell reinforcement (CR), which ... second integration extending from time t into the future up to t + ∆. The acausality of integrating into the future can be taken care of by time shifting the integration variable in t...

... communication SNR levels. It is interesting to see that using more training symbols does not improve the performance of the MLE as expected, because inserting training symbols will reduce the energy ... Furthermore, since the estimation quality of the first stage is available, we use BLUE to obtain ˆ θ for exploiting the quality information instead of using the MLE in the M-step as in th...
