This study introduces a Fisher-Rao guided framework for structured channel pruning, significantly reducing model parameters and FLOPs while maintaining high accuracy. The method offers a reliable and efficient approach to model compression for deep learning applications.
Area of Science:
- Computer Science
- Artificial Intelligence
- Machine Learning
Background:
- Structured channel pruning is key for efficient deep learning models.
- Reliability hinges on importance criteria and pruning schedules.
Purpose of the Study:
- To develop a robust framework for structured channel pruning.
- To improve model compression efficiency and reliability.
Main Methods:
- Proposed a Fisher-Rao guided framework for channel scoring.
- Utilized diagonal empirical Fisher approximation.
- Incorporated progressive re-estimation and short recovery training.
Main Results:
- Achieved significant parameter/FLOP reduction on CIFAR-10 (e.g., ResNet-110: 85.5%/66.8%) and ImageNet (e.g., ResNet-50: 60.0%/50.1%).
- Maintained high accuracy on ImageNet (e.g., ResNet-50: 75.65% Top-1).
- Demonstrated backbone-dependent sensitivity in recovery-free diagnostics.
Conclusions:
- The Fisher-Rao guided framework is an effective baseline for classification pruning.
- The method is loss-coupled and budget-controlled, adaptable to various architectures.
