Overfitting happens when a model learns too much detail from training data, including noise, rather than general patterns.

Result: The model performs well on training data but poorly on new, unseen data.

Symptoms: High accuracy on training data, low accuracy on test data.

Cause: Model is too complex (e.g., too many layers, features, or parameters).

Example: Memorizing answers for a specific test rather than understanding concepts.

Solution: Simplify the model, use regularization techniques, or gather more data.

Purpose of Avoiding Overfitting: Ensures the model can generalize and make accurate predictions on new data.
