A logistic regression classifier to recognize cats. Also the first programming assignment on Neural Network and deep learning of Andrew Ng
"cat_reg_lr_tf" is the tensorflow implement and "cat_reg_lr_keras" is the keras implement.
Through comparing the three methods. The keras is the most easy, then tensorflow and finally python code. The keras implement don't need to care about the Mathematical equations and define the variable and placeholder compare to tensorflow. It is very easy to use.
