Definition
Negative transfer worsens a task due to inappropriate transferred prior knowledge.
A deterioration of the target task because transferred representations or prior knowledge are not suitable.
Simply explained
What helped in an old task can lead in the wrong direction in a new task.
Why it matters in practice
Helps realistically assess model quality, limits, and technical decisions.
Example from business
A model pretrained on general photos worsens a specific material test compared to training without transfer.
Limits and pitfalls
- Calling every weak fine-tuning negative transfer or not controlling baseline and data amount.
Origin & history
The term originates from learning research and transfer learning.
Use in mid-sized companies
- Possible application: A model pretrained on general photos worsens a specific material test compared to training without transfer.
