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). Witryna8 cze 2016 · Suppose we replace the loss function of the logistic regression (which is normally log-likelihood) with the MSE. That is, still have log odds ratio be a linear function of the parameters, but minimize the sum of squared differences between the estimated probability and the outcome (coded as 0 / 1): log p 1 − p = β 0 + β 1 x 1 +... + β n x n.
