Muuttujavalintaa
Muuttujavalintaa, also known as variable selection, is a crucial process in statistical modeling and machine learning. It involves identifying and selecting a subset of relevant variables from a larger set of potential predictors to be included in a model. The primary goals of muuttujavalintaa are to improve model performance, enhance interpretability, and reduce computational complexity.
There are several reasons why muuttujavalintaa is important. Firstly, it can help to avoid overfitting, a situation
Common approaches to muuttujavalintaa can be broadly categorized into filter methods, wrapper methods, and embedded methods.
