Step 3: Look at the options provided in the question and see if any of them are not related to feature extraction.
Step 4: Recognize that Linear Regression is a technique used to create a model, not to extract features from data.
Step 5: Conclude that Linear Regression is the correct answer to the question as it is NOT a method of feature extraction.
