What is overfitting in the context of machine learning models?

Q: Answer-What is overfitting in the context of machine learning models?

Overfitting occurs when a machine learning model is too complex relative to the amount of training data available. In this situation, the model learns not only the underlying patterns in the training data but also the noise and random fluctuations. As a result, the model performs exceptionally well on the training data but fails to generalize to new, unseen data.

A A scenario where a model performs well on both the training data and unseen test data.

B A condition where a model is too complex and captures noise in the training data, leading to poor generalization on new data.

C A process of simplifying a model to improve its performance on the training dataset.

D A technique to ensure that a model is trained with a sufficient amount of data to avoid bias.

E A strategy for improving model performance by using cross-validation to tune hyperparameters.
