In the realm of machine learning and data science, the importance of having clean, well-prepared data cannot be overstated. While collecting a vast amount of data has become easier than ever, not all data components contribute equally. This is where the art and science of feature selection become essential. Feature selection is a critical step in the machine learning workflow, aimed at improving model performance, reducing computational cost, and enhancing model interpretability. Let’s delve deeper into the concept and methods of feature selection.
