## Feature Selection

Feature selection is the process of identifying and choosing the most relevant input variables for a predictive model. In the vast landscape of crypto and derivative data, many variables may be irrelevant or noisy, which can distract the model and lead to overfitting.

By selecting only the features that have a proven, statistically significant relationship with the target variable, traders can build more efficient and robust models. This can be done through various statistical tests or model-based importance rankings.

Effective feature selection improves model performance, reduces training time, and enhances interpretability. It ensures that the model is built on solid foundations rather than spurious patterns.

This is a critical step in any rigorous quantitative modeling pipeline.
