Python library for dot product classification

I have the following python pyseudo-code: A1 = "101000001111" A2 = "110000010101" B2 = "000111010000" B2 = "000110100000" # TODO get X = [x1, x2, ..., x12] assert(A1 * X > .5) assert(A2 * X > .5) assert(B1 * X < .5) assert(B2 * X < .5) So this will…

Confusion matrix fails to show all labels

I have created a classification matrix for multi-label classification to evaluate the performance of the MLPClassifier model. The confusion matrix output should be 10x10 but at times I get 8x8 as it doesn't show label values for either 1 or 2 class…
