Webb10 apr. 2024 · There are 2 main causes of this- underfitting and overfitting. We will see both these situations in detail in this post. Overfitting Let us understand overfitting from a supervised machine learning algorithm’s perspective. Supervised algorithms sole purpose is to generalize well on never-before-seen data. WebbFeature extraction is a part of the dimensionality reduction process, in which, an initial set of the raw data is divided and reduced to more manageable groups.
