Question: What is the role of feature scaling in machine learning?

Options:

Correct Answer: To ensure all features contribute equally to the model

Solution:

Feature scaling ensures that all features contribute equally to the model by standardizing or normalizing their values.

What is the role of feature scaling in machine learning?

Step 1: Understand that features are the different inputs or variables used in a machine learning model.
Step 2: Realize that features can have different ranges of values (e.g., age from 0-100 and income from 0-100,000).
Step 3: Know that if features have different ranges, the model may give more importance to features with larger values.
Step 4: Learn about feature scaling, which adjusts the values of features to a similar range.
Step 5: Identify two common methods of feature scaling: standardization (making values have a mean of 0 and a standard deviation of 1) and normalization (scaling values to a range of 0 to 1).
Step 6: Understand that feature scaling helps the model learn better and faster by ensuring all features contribute equally.
