I was wondeing if it is possible to put weights on false positive and false negatives, the same as the misclassification cost array in random forest and SVM?
Explaining what I mean by misclassification cost: Misclassification cost, specified as a numeric square matrix, where Cost(i,j) is the cost of classifying a point into class j if its true class is i. For two-class learning, if you specify the cost matrix ? (see Cost), then the software updates the class prior probabilities p (see Prior) to pc by incorporating the penalties described in ?. (at https://au.mathworks.com/help/stats/classificationsvm.html)
Defining C in a matrix like this (C=[0 alpha beta 0]) you will be able to put weights on FP and FN by varying beta and alpha. Is this also possible in neural nets?

Hi, did you figure it out? I'm currently facing the same problem. Thanks!
