WebWe can see that a linear function (polynomial with degree 1) is not sufficient to fit the training samples. This is called underfitting. A polynomial of degree 4 approximates the true function almost perfectly. However, for higher degrees the model will overfit the training data, i.e. it learns the noise of the training data.

WebMar 2, 2024 · Overfitting happens when: The training data is not cleaned and contains some “garbage” values.
