I understand but what I meant is that to train a logistic regression  
you need data that is made of a X matrix which represents the input  
data. Lets say we have 'm' examples. We also need a Y vector which  
represent the expected outputs for each of the 'm' training example.  
The training process is simply fitting the weights of the regression  
so the output of the regression is almost always outputs the right Y  
when you give an input X. I wanted to know how you are able to find  
the Y vector which is the expected output of the regression for the  
input data? Am I understanding correctly?
