Data Science and Machine Learning (Theory and Projects) A to Z - Overfitting, Underfitting, and Generalization: Overfitt

This video tutorial discusses the concept of overfitting in machine learning, a common challenge faced by algorithms. It explains how more flexible models, such as higher-degree polynomials, can fit training data perfectly but may lead to overfitting. The tutorial uses regression as an example to illustrate how increasing model flexibility can result in zero training error but poor generalization to new data. The video concludes by highlighting the problems of overfitting and introduces the next steps to explore these issues further using Jupyter notebooks.
