Question: In the context of model evaluation, what does \'overfitting\' refer to?

Options:

Correct Answer: Model performs well on training data but poorly on unseen data

Solution:

Overfitting occurs when a model learns the training data too well, capturing noise and failing to generalize to new data.

In the context of model evaluation, what does 'overfitting' refer to?

Step 1: Understand that a model is a set of rules or patterns that we create to make predictions based on data.
Step 2: When we train a model, we use a specific set of data called 'training data'.
Step 3: Overfitting happens when the model learns the training data too perfectly, including all the small details and noise.
Step 4: Because of this, the model becomes very good at predicting the training data but struggles to make accurate predictions on new, unseen data.
Step 5: In simple terms, overfitting means the model is too specialized to the training data and cannot generalize well.
