Explain FEATURE ENGINEERING: “To obtain a good model, however, often requires more effort and iteration and a process called feature engineering. Features are the model’s inputs. They can involve basic raw data that you have collected, such as order amount, simple derived variables, such as ‘Is order date on a weekend? Yes/No,’ as well as more complex abstract features, such as the ‘similarity score’ between two movies. Thinking up features is as much an art as a science and can rely on domain knowledge.”[anderson] See also feature.
