-the one that called one-vs-all classification algorithm

classification with more than two groups

classification with more than two groups

either starting from index 0 or 1 doesn't matter..

the defined algorithms earlier is to compute the binary by using logistic regression...

using one vs all algorithm for solving multiclass classification.

- the algorithm is essentially make two groups,Â with each class again the rest...and take each hypothesis(that denotes by superscript) for each class
