Logistic regression is a powerful statistical method that is used to model the probability that a set of explanatory (independent or predictor) variables predict data in an outcome (dependent or ...

The function exp(x) is Euler's number, approximately 2.718, raised to the power of x. If y = exp(x) the Calculus derivative is y * (1 – y) which turns out to be important when training a basic ...

If the signal to noise ratio is low (it is a ‘hard’ problem) logistic regression is likely to perform best. In technical terms, if the AUC of the best model is below 0.8, logistic very clearly ...
