On the Interaction Between Model Compression and Test-Time Adaptation
TL;DR
This study investigates the interplay between model compression and test-time adaptation (TTA) in deep neural networks. It finds that while compressed models maintain high accuracy during supervised adaptation, their TTA performance significantly declines as compression increases due to reduced representational diversity.
✦ Why It Matters
Focus on designing compression methods that enhance model adaptability to improve TTA performance.
Key Takeaways
- Evaluate the impact of compression on TTA performance.
- Consider representational diversity when compressing models.
- Use diagnostic frameworks to assess model adaptability.
- Design compression strategies that prioritize adaptability.
How It Works
The study introduces a diagnostic framework that evaluates how well a compressed model can adapt to new data distributions. It focuses on representational expressivity, which refers to the model's ability to capture complex patterns, and adaptation subspace compatibility, which assesses how well the model can adjust to changes in data distribution.
