This is a guide to Bayes Theorem. Here we discuss the use of bayes theorem in machine learning and the portrayal used by naive bayes models with examples. You may also have a look at the following articles to learn more – Naive Bayes Algorithm Machine Learning Models Machine Learning Methods...
As the Naive Bayes algorithm has the assumption of the “Naive” features it performs much better than other algorithms like Logistic Regression, Tree based algorithms etc. The Naive Bayes classifieris much faster with its probability calculations. Why do naive Bayesian classifiers perform so well?

The Naive Bayes algorithm did not require hyperparameter tuning, and its default settings were used. It still achieved a respectable \({F}_{1}\) score of 0.94. Finally, the Logistic Regression algorithm was tuned for the hyperparameters regularization strength, max_iter, and penalty. The best...

Choose the Naive Bayes algorithm: Click the “Choose” button and select “NaiveBayes” under the “bayes” group. Click on the name of the algorithm to review the algorithm configuration. Weka Configuration for the Naive Bayes Algorithm
If you are looking for an area to specialize in using Weka, a source of true power in the platform besides ease of use, I would point to the support for ensemble techniques. Machine Learning Algorithm Configuration Once you have chosen a machine learning algorithm, you can configure it. ...
Naïve Bayes algorithm was adopted for a specific amount of water according to the crop needs. By adopting this proposed method, proper water management can be achieved. In a different study, researchers (Xie et al., 2017) suggested a framework to support irrigation systems. The framework ...
