Basic Machine Learning in Excel - Text Classification with a Naive Bayesian Classifier

Описание

This video gives a quick introduction to Bayes' Theorem and one of the most basic Machine Learning algorithms, a Naive Bayes Classifier.

I look at two simple examples, one for predicting if someone will play golf based on the weather, and one for classifying movie reviews as positive or negative.

This first example is based on the data in this article:

The second example is based on the data in this article:
