Q. In the context of neural networks, what is 'overfitting'?
A.
When the model performs well on training data but poorly on unseen data
B.
When the model has too few parameters
C.
When the model is too simple to capture the data patterns
D.
When the model converges too quickly
Solution
Overfitting occurs when a model learns the training data too well, including noise, leading to poor generalization on new data.
Correct Answer:
A
— When the model performs well on training data but poorly on unseen data
