Generalization Errors in Machine Learning: Python Examples

Generalization Errors in Machine Learning

Last updated: 21st Jan, 2024 Machine Learning (ML) models are designed to make predictions or decisions based on data. However, a common challenge, data scientists face when developing these models is ensuring that they generalize well to new, unseen data. Generalization refers to a model’s ability to perform accurately on new, unseen examples after being trained on a limited set of data. When models don’t generalize well, they commit errors. These errors are called generalization errors. In this blog, you will learn about different types of generalization errors, with examples, and walk through a simple Python demonstration to illustrate these concepts. Types of Generalization Errors Generalization errors in machine learning …
