Witryna24 gru 2024 · I think I understand quite well what the LogisticRegression does.It computes the coefficients and intercept to minimise half of sum of squares of the coefficients + C times the binary cross-entropy loss, where C is the regularisation parameter. I checked against a naive implementation from scratch, and results coincide. WitrynaThe logistic regression is implemented in LogisticRegression. Despite its name, it is implemented as a linear model for classification rather than regression in terms of the scikit-learn/ML nomenclature. The logistic regression is also known in the literature as logit regression, maximum-entropy classification (MaxEnt) or the log-linear classifier.
