Why is Feature Selection Basics important in Machine Learning Fundamentals
BeginnerAnswer
Good feature selection improves model accuracy, reduces training time, and makes the model easier to understand. Too many irrelevant features can confuse the model and slow it down.
Real-world example A hospital predicting patient risk may start with fifty medical measurements but use feature selection to narrow it down to the ten most useful ones, making the model faster and easier to explain to doctors.
