http://ufldl.stanford.edu/wiki/index.php/Exercise:Softmax_Regression WebSoftmax regression applies to classification problems. It uses the probability distribution of the output class in the softmax operation. Cross-entropy is a good measure of the difference between two probability distributions. It measures the number of bits needed to encode the data given our model. 3.4.10. Exercises ...
