wQloss function
A function to evaluate the weighted quadratic loss function and the derivative of this function to be used when training a neural network.
wQloss(w)
w |
a vector of weights, adding up to 1, whose length is equalt to the output length of the net |
a list object with elements that are functions, evaluating the loss and the derivative

# Example in context: netwts <- train(dat=train_set, truth=truth, net=net, eps=0.001, tol=0.95, loss=wQloss(c(10,5,6,9)), # here assuming output of length 4 batchsize=100)
