Witryna6 gru 2024 · Logistic Regression vs KNN : KNN is a non-parametric model, where LR is a parametric model. KNN is comparatively slower than Logistic Regression. KNN supports non-linear solutions where LR supports only linear solutions. LR can derive confidence level (about its prediction), whereas KNN can only output the labels. 3.
