The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

our work shows how spiking neural networks can learn recurrent excitatory connections with delays to maintain a record of the recent past and successfully predict the future.

C2weakest assumption

That spike timing-dependent plasticity applied to recurrent connections with delays is sufficient to learn and maintain the necessary short-term memory traces for accurate future prediction without additional mechanisms or labeled supervision.

C3one line summary

PCL+ spiking network learns recurrent connections with delays via STDP to retain recent visual inputs and predict future ones, reproducing cortical sequence learning and filling missing data in gesture recognition.
