On the other hand, what would a generative model do? Well, its aim will be to ultimately give us this same probability, but the process it will follow to do so will be a little bit different. Let’s suppose we have p(x|yk) and p(yk). Then, Bayes rule will allow us to find ...
is a direct approach to model the probability of interest. Compare this with Logistic regression: there, the probability is modeled using a linear function with a sigmoid function applied on top of it. It’s still an easy model, but it does not feel as natural as a naive Bayes classifier...

Naive Bayes isa machine learning modelthat is used for large volumes of data, even if you are working with data that has millions of data records the recommended approach is Naive Bayes. It gives very good results when it comes to NLP tasks such as sentimental analysis. How is naive Bayes ...
Classical and Bayesian Naive Bayes Classifiers Introduction The naïve Bayes (NB) classifier is a family of simple probabilistic classifiers based on a common assumption that all features are independent of each other, given the category variable. The different NB classifiers differ mainly by the ass...
I had to transpose the output in order to get the same structure as the naiveBayes model output. Finally, I printed out my calculated conditional probabilities and compared them with the naiveBayes output to validate the calculations. Applying the Naive Bayes’ Classifier So I’ve explained (...

Such an example is the Minimum Log-likelihood Difference WNB (MLD-WNB), which optimizes weights according to the Bayes optimal decision rule and provides hyperparameters to control the bias of the model (Ferreira et al., 2001). Various methods can be used to improve the performance of ...
