If you want to check the correctness of this, you can plug in the numbers from the above example on conditional probabilities, and you will find that both sides equal to 4/7. Naive Bayes classifier Let’s now take the above equation and change the notation to make it more relevant ...

The proposed method is to involve programming as a didactic tool in hard-to-teach topics. The intended goal in this case is to implement a nave Bayes-classifier algorithm in Python and demonstrate the machine-learning capabilities of it by applying it to a real-world dataset of ...
Python机器学习算法 — 朴素贝叶斯算法(Naive Bayes) 朴素贝叶斯算法 -- 简介 朴素贝叶斯法是基于贝叶斯定理与特征条件独立假设的分类方法。最为广泛的两种分类模型是决策树模型(Decision Tree Model)和朴素贝叶斯模型(Naive Bayesian Model,NBM)。 和决策树模型相比,朴素贝叶斯分类器(Naive Bayes Classifier,或 NBC)发源...
