The demo doesn't save the trained model. When using scikit, the most common way to save a trained naive Bayes classifier model is to use the pickle library ("pickle" means to preserve in English, as in "pickled cucumbers"). For example: import pickle print("Saving Gaussian naive Bayes m...
as they come in many flavors. For example, there is a multinomial naive Bayes, a Bernoulli naive Bayes, and also a Gaussian naive Bayes classifier, each different in only one small detail, as we will find out. The naive Bayes algorithms are quite simple in design but proved useful in man...
3. Naive Bayes Classifier 朴素贝叶斯是另一种概率生成模型,基于条件独立性假设,可看作一种最简单的概率有向图模型。 变量x的各个维度在给定y的条件下是相互独立的。这个假设虽然不一定合理,但却能大大简化运算,这就是朴素贝叶斯的目的。 基于条件独立性假设,可以有: P(x∣y)=∏j=1pP(xj∣y)y^=argmaxy...

Conditional Probability Example Using the Bayes theorem the naive Bayes classifier works. The naive Bayes classifier assumes all the features are independent to each other. Even if the features depend on each other or upon the existence of the other features. Naive Bayes classifier considers all of...

Naïve Bayes Let’s try with a naïve Bayes classifier as well. First, we will define the model function: # Create model function # # train_data : tibble with the training data # formula : a formula object # hyperparameters : a named list of hyparameters nb_model_fn <- function(tr...
