# Personalize Algorithm

Personalize Algorithm in AWS refers to a custom or predefined machine learning algorithm used within Amazon Personalize to generate personalized recommendations. It defines the logic and training approach behind recommendation models, such as collaborative filtering or deep learning methods. The resource provides details about the algorithm, including its name, ARN, supported features, and training requirements, helping users understand how it can be applied to build tailored recommendation systems.
