Core Concepts
Representation Enhanced Analytic Learning (REAL) improves class-incremental learning by enhancing representations and knowledge transfer.
Abstract
The content introduces REAL, a method for exemplar-free class-incremental learning. It proposes a dual-stream base pretraining (DS-BPT) and representation enhancing distillation (RED) process to enhance the extractor's representation. REAL outperforms existing methods on various datasets.
Introduction:
Class-incremental learning allows models to adapt to new data phases.
Catastrophic forgetting is a challenge in CIL.
Related Works:
Replay-based CIL stores historical data for memory reinforcement.
Exemplar-free CIL addresses privacy concerns without exemplars.
Proposed Method:
REAL focuses on representation enhancement with DS-BPT and RED processes.
Experiments:
REAL outperforms state-of-the-art EFCIL methods on CIFAR-100, ImageNet-100, and ImageNet-1k datasets.
Conclusion:
REAL enhances representations and knowledge transfer in class-incremental learning.
Stats
Empirical results on various datasets including CIFAR-100, ImageNet-100, and ImageNet-1k demonstrate that our REAL outperforms the state-of-the-art in EFCIL, and achieves comparable or even more superior performance compared with the replay-based methods.
