  1. \(\dim g\) is the dimension of the g vector. All other vectors, if present, are 200-dimensional. Matrix densities \((\rho _G, \rho _P, \rho _E, \rho _H)\) are chosen to ensure that the number of non-zero elements is equal between different models on average. Our study used \(\rho _0 = 0.02\). \(\omega _f,\omega _g,\omega _h\) and \(\omega _p\) are scaling constants for the input of the respective activation functions (squared values are shown; see "Methods").
