Develop a privacy-aware feature distillation framework that prevents the direct exposure of proprietary teacher representations without sacrificing student model accuracy.
Designed a low-rank projection strategy that obfuscates teacher intermediate representations into a compact subspace.
Enabled authorized student models to align their intermediate features with the projected teacher subspace during training.
Evaluated empirical feature obfuscation, reconstruction resistance, and transfer effectiveness across object detection and semantic segmentation benchmark datasets.
Achieved empirical feature obfuscation and robust resistance against representation reconstruction attacks.
Maintained competitive performance on object detection and semantic segmentation tasks compared to traditional feature distillation.
Demonstrated performance improvements in several experimental settings despite restricting student training to projected representations.
