SPIDER The Spider Objects
Normalization object - simple normalization of data A=NORMALIZE(H) returns a normalize object initialized with hyperparameters H. Performs different kinds of pre-processing on data. Hyperparameters, and their defaults a.scale_type=0 -- 0: do nothing, 1: columns have mean 0, std 1 2: rows have mean, std 1 3: try to do do both 1 & 2 4: scale by correlation coefficients a.sigmoid=0 -- yes or no, scale features nonlinearly through a sigmoid, i.e f(x)=tanh(sig*x) Model parameters mean_vec -- threshold vectors scale_vec -- scaling factors sig -- sigmoid steepness parameter corr -- correlation coefficients
