Logistic regression naive bayes
WitrynaIntroduction Naive Bayes and logistic regression are two basic machine learning models that are compared frequently, especially as the generative/discriminative counterpart of one another. However at first sight it seems these two methods are rather different. In naive Bayes we just count the frequencies of features and labels while in … WitrynaLogistic Regression is often referred to as the discriminative counterpart of Naive Bayes. Here, we model P ( y x i) and assume that it takes on exactly this form P ( y x i) = 1 1 + e − y ( w T x i + b). We make little assumptions on P ( x i y), e.g. it could be Gaussian or Multinomial.

Learning curves show the effect of adding more samples during the training process. The effect is depicted by checking the statistical performance of the model in terms of training score and testing score. Here, we compute the learning curve of a naive Bayes classifier and a SVM classifier with a RBF kernel using the digits ...

Witryna15 lut 2024 · In this proportion logistic regression and Naïve Bayes have the same specificity rate which is 1.0 and it means that both the classifiers classified the negative cases (non-fraud) with 100% accuracy. This might be due to reason, as the training data sample increases the accuracy of both the classifiers increases.
