As a start, I wrote just the core of the framework and implemented a first toy example. Thanks advance! In the former case, the output values are independent while in the latter, the output values add up to 1. The main difference between the hinge loss and the cross entropy loss is that the former arises from trying to maximize the margin between our decision boundary and data points - thus attempting to ensure that each point is correctly and confidently classified*, while the latter comes from a maximum likelihood estimate of our model's parameters. This means we take a negative number, raise it to the power of the logarithm of y (which will be positive), and then subtract this from our original calculation.
