Research on Sparsity of Output Synapses in Echo State Networks

Table 1

Weights of output synapses when all output synapses are activated and the 2nd or 4th synapse is silenced, respectively. Here are the ratio between the weights of synapses when the 2nd or 4th synapse is silenced and the weights when all synapses are activated.
