Reservoir Computing Properties of Neural Dynamics in Prefrontal Cortex
Fig 9
Error rates of the model as a function of the number of neurons in the reservoir (30 simulations, shaded area correspond to standard error).
The model required less neurons to perform well when phase information was explicitly represented in the trained context neuron. Error rates were computed as the ratio between the number of suboptimal trials (choices that likely postpone the reward) over the total number of trials. The reservoir required ~400 neurons to perform the task optimally with phase information explicitly encoded in a readout neuron, vs. ~1000 neurons that were required without the context neuron.
