This classification model is very easy to implement and performs very well in linearly separable classes.
Decreasing the cost will increase the maximum likelihood assuming that samples are drawn from an identically independent distribution. Log odds If we take into consideration the conditional probability of getting an output P y1xw is equal to the sigmoid function and the p y0xw 1-p y0xw and if take in that our. We will also see the math you need to k. This justifies the name logistic regression.
