“…In the low-rank case a set of prototypical signals V V V combine linearly through a set of coefficients Q Q Q to generate more generally correlated input streams. Maass et al, 2002;Ganguli & Sompolinsky, 2010;Wallace, Hamid, & Latham, 2013;Verstraeten, Schrauwen, dHaene, & Stroobandt, 2007;White, Lee, & Sompolinsky, 2004;Lukoševičius & Jaeger, 2009;Buonomano & Maass, 2009;Charles, Yap, & Rozell, 2014). For example, if the state of the network at time N can recover s s s 1 up to s s s N , then we can say that the number of recoverable inputs (the STM) is LN.…”
