1. 피처 엔지니어링(Feature Engineering)이란? "Feature engineering is the process of using domain knowledge to extract features from raw data via data mining techniques. These features can be used to improve the performance of machine learning algorithms."[1] 피처 엔지니어링은 최초 데이터(raw data)를 데이터 마이닝 기법을 통해 피처로 만들어서 머신 러닝 알고리즘의 성능을 향상시키는 일련의 과정이다. "The purpose of a feature, other than being an attribute, would ..
