9. What is overfitting in machine learning?

Overfitting occurs when a machine learning model performs well on the training data but fails to generalize to new, unseen data. It happens when the model becomes too complex and starts to memorize the training data instead of learning the underlying patterns.

10. How can overfitting be prevented?

Overfitting can be prevented by using techniques such as cross-validation, regularization, and feature selection. These techniques help to reduce the complexity of the model and improve its generalization ability.

11. What is feature engineering?

Feature engineering is the process of selecting, transforming, and creating new features from the raw data to improve the performance of machine learning models. It involves domain knowledge and understanding of the data.

12. What is the bias-variance tradeoff?

The bias-variance tradeoff is a fundamental concept in machine learning. It refers to the tradeoff between the bias (underfitting) and variance (overfitting) of a model. A model with high bias has low complexity and may not capture the underlying patterns, while a model with high variance is too complex and may overfit the training data.

13. What is cross-validation?

Cross-validation is a technique used to assess the performance of a machine learning model. It involves splitting the data into multiple subsets, training the model on some subsets, and evaluating it on the remaining subset.
