Transfer Learning vs Fine-Tuning

Transfer learning

Transfer learning means taking a pretrained model (SAM3) and adapting it to a new domain or task instead of training from scratch.

In this project:

  • Start from pretrained SAM3 weights.
  • Train only selected parts (or small adapter modules) on forest data.

Fine-tuning

Fine-tuning is the training step used during transfer learning.

In this project:

  • Continue training SAM3 on labeled forest imagery.
  • Use lower learning rates and domain-specific data.

Relationship:

  • Transfer learning is the strategy.
  • Fine-tuning is the mechanism.
