When Should I Use Transfer Learning?
Transfer learning is a powerful technique in deep learning that allows you to leverage pre-trained models to improve the performance of your own model. Here are several scenarios when you should consider using transfer learning:
- 1. Limited Data: When you have a small dataset, transfer learning can help utilize knowledge from larger datasets to enhance model training.
- 2. Domain Similarity: If your target task is similar to the pre-trained model's task (e.g., using an image classifier trained on ImageNet for medical image classification), transfer learning can yield excellent results.
- 3. Time Constraints: Training a model from scratch can be time-consuming; using a pre-trained model cuts down the training time significantly.
- 4. Prototyping: For quick prototyping, transfer learning can facilitate swift model development while still achieving reasonable accuracy.
- 5. Resource Constraints: If computational resources are limited, transfer learning can be a cost-effective solution that avoids the need for extensive computational power.
In summary, transfer learning is beneficial when you face data limitations, need efficiency, or aim to improve performance on similar tasks.
