Predict_proba for Binary classifier in Tensorflow
Since a neural net that ends with a sigmoid activation outputs probabilities, you can take the output of the network as is. 

If you're referring to scikit-learn's predict_proba, it is equivalent to taking the sigmoid-activated output of the model in tensorflow. In fact that's exactly what scikit-learn does.

E.g. if tour model outputs $0.8$ for class $1$, you would classify this as $1$ (since $0.8 &gt; 0.5$), with a probability of $0.8$. S
