Machine learning (ML) is the scientific study of algorithms and statistical models that computer systems use to perform a specific task without being explicitly programmed. Second, the data sampling for train and test data is of crucial importance for reliable results. Importance sampling is a way of estimating expectations under an intractable distribution p by sampling from a tractable distribution q and reweighting the samples according to the ratio of the probabilities. Also known as binomial logistic regression, this algorithm finds the probability of an event's success or failure. It is derived from a little mathematic transformation and is able to formulate the problem in another way. Introduction.
