# Bayes’ Theorem in Machine Learning

Learn how Bayes’ theorem is used in machine learning problems, i.e., clustering, classification, and regression.

## We'll cover the following

One of the main ways Bayes’ theorem is used in machine learning is in developing probabilistic models that are used to make predictions about the likelihood of different outcomes based on data. These models typically involve the specification of a probability distribution, representing uncertainty about the outcome of interest. Bayes’ theorem can then be used to update the probability distribution based on new data or other evidence to refine the predictions made by the model.

## Examples of Bayesian statistics in machine learning

Here are a few examples of the usage of Bayes’ theorem in machine learning.

### Classification

Bayes’ theorem can be used to update the probability distribution over different classes based on the observed features of the data. For example, in a binary classification task, Bayes’ theorem can be used to update the probability that a given data point belongs to one of the two classes based on the observed features of the data point. This can improve the accuracy of classifiers by incorporating additional information about the data.
