WitrynaMany classifiers can predict continuous scores. Often, continuous scores are intermediate results that are only converted to class labels (usually by threshold) as the very last step of the classification. In other cases, e.g. posterior probabilities for the class membership can be calculated (e.g. discriminant analysis, logistic regression). WitrynaLogistic. Logistic regression is a process of modeling the probability of a discrete outcome given an input variable. ... As opposed to linear regression where MSE or RMSE is used as the loss function, logistic regression uses a loss function referred to as “maximum likelihood estimation (MLE)” which is a conditional probability. ...
