Default Re: Q10 Clarification required

Hello all:

I answered this question incorrectly. I think my confusion arises from considering that the error function must be differentiable, because we are after all taking the gradient vector. In reading the following:

Quote:
So if there is no error for the selected data point, then there is no change to the weights. If there is an error for the selected data point, then the weights are increased by yn * xn
I realize that it contains the answer if you read between the lines, but what if the implied answer is not differentiable?
