Robust and brain-like working memory through short-term synaptic plasticity
Fig 7
Distances between neural trajectories within a sample condition and between sample conditions, for fixed synapse RNNs.
All models used were the most ‘brain-like’, as determined by the methodology in section “RNNs With STSP are More Brain-Like”. a) Cartoon of trial-averaged RNN trajectories corresponding to two different sample conditions for the fixed-synapse RNNs. a1) Average pairwise distance between trajectories on different sample conditions, for the fixed synapse network with tanh activation (FS-tanh). a2) The same plot as in a1, but for FS-relu. b1) The average distance between distracted and undistracted trajectories. Average taken over all sample conditions. Results shown for FS-tanh. b2) Same results as in b1, but for FS-relu.
