If one feature is measured in millions (like house prices) and another in single digits (like the number of bedrooms), the model might mistakenly think the larger numbers are more important. Scaling brings everything into a consistent range.

Dealing with missing values by filling them with averages, medians, or educated guesses so the model doesn't crash or become biased. Feature Engineering for Machine Learning and Da...

Identifying data points that are so extreme they might skew the model’s understanding of "normal" behavior. If one feature is measured in millions (like

The Art of Data Sculpting: Feature Engineering in Machine Learning if you have a "Timestamp

This is the creative part. For example, if you have a "Timestamp," you might create a new feature called "Is_Weekend" or "Hour_of_Day." These derived attributes often hold the key to high accuracy. The Creative Challenge
