Question: What is transfer learning in deep learning?

Options:

1. Training a model from scratch on a new dataset
2. Using a pre-trained model on a new but related task
3. Fine-tuning a model on the same dataset
4. Applying unsupervised learning techniques

Correct Answer: Using a pre-trained model on a new but related task

Solution:

Transfer learning involves using a pre-trained model on a new but related task, which can save time and resources.
