WitrynaDue to its simplicity, efficiency, and effectiveness, multinomial naive Bayes (MNB) has been widely used for text classification. As in naive Bayes (NB), its assumption of the conditional independence of features is often violated and, therefore, reduces its classification performance. Of the numerous approaches to alleviating its assumption … WitrynaLater, Zhang et al. integrated naive Bayes, three-way decision and collaborative filtering algorithm, and proposed a three-way decision naive Bayes collaborative filtering …

Witryna15 sie 2024 · Bayes’ Theorem provides a way that we can calculate the probability of a hypothesis given our prior knowledge. Bayes’ Theorem is stated as: P (h d) = (P (d h) * P (h)) / P (d) Where P (h d) is the probability of hypothesis h given the data d. This is called the posterior probability. WitrynaNaive Bayes algorithm is uncomplicated and effective in text classification and experiments. However, its performance is often imperfect because it does not model …
