Witryna1 paź 2016 · In particular, the most accurate model with high predictive power was the eighth model (five variables and 92 training data), with the Naïve Bayes classifier having a slightly higher overall performance and accuracy than the Logistic Regression classifier, 87.50% and 82.61% on the validation datasets, respectively. Witryna14 wrz 2024 · Logistic Regression. We saw how a generative classifier, the Naive Bayes model, works. It assumes some functional form for ^P (X Y) P ^ ( X Y), ^P (Y) P ^ ( Y) and estimates parameters of P from training data. It then uses Bayes rule to calculate ^P (Y X =x) P ^ ( Y X = x). In generative models, the computation of P (Y …
