BRN results for different encoding schemes. (A, B) maximum capacity and memory (product of maximum delay and step duration) for the spatial encoding scheme averaged over five trials with different network and input initialisations. The standard deviation across trials is too small to be visible. (C, D) as for (A, B), but with amplitude encoding. (E,F ) as for (A, B), but with distributed encoding. (G, H) Heat maps for total capacity, maximum degree and maximum delay for the parameter scans marked with a circle and a square in A and B. (I, J) Capacity profiles showing total and degree-specific capacities as functions of delay for the parameter configurations indicated by the magenta and yellow boxes in (G) and (H) Note the different axis and color scales in these panels. (K, L) Correlations between capacity statistic and task performances for the same parameter ranges of \(a_{\max}\) and \(\Delta _s\) as shown in (G) and (H), using DC input and frozen noise; \(p=1\) in (K) and \(\sigma = 20\) in (L).
