What are the benefits of feature engineering in machine learning?

Feature engineering helps improve model accuracy, reduces overfitting, and enhances interpretability.

Can you give me some examples of effective feature engineering techniques?

Sure! Techniques include normalization, one-hot encoding, and creating interaction features.

How does feature engineering impact model performance?

Good feature engineering can significantly boost model performance by providing relevant information.

Is feature engineering necessary for all machine learning models?

Not always, but it is crucial for many models, especially those that rely heavily on input data quality.
