Fig. 6: Simultaneous training of multiple clusters.

a Schematic of clusters on the chip. One core contains excitatory populations, and another contains inhibitory populations. We implemented five E/I networks, with each network comprising 50 excitatory and 15 inhibitory neurons. As per table 1, the connection probability within these networks is 0.35. To account for the network’s scaling, we defined higher set-points. Note that these clusters do not interconnect with one another. b Rate convergence for five clusters sharing the same nominal weights. Each color represents one cluster.
