Two-Way Is Better Than One: Bidirectional Alignment with Cycle Consistency for Exemplar-Free Class-Incremental Learning
arXiv:2606.05675v1 Announce Type: new Abstract: Continual learning (CL) seeks models that acquire new skills without erasing prior knowledge. In exemplar-free class-incremental learning (EFCIL), this challenge is amplified because past data cannot be stored, making representation drift for old classes particularly harmful. Prototype-based EFCIL is attractive for its efficiency, yet prototypes drift as the embedding space evolves; therefore, projection-based drift compensation has become a popular remedy. We show, however, that existing one-directional projections introduce systematic bias: the
The continuous evolution of AI models demands methods to learn new information without compromising prior knowledge, especially as models become larger and more complex. Research into efficient class-incremental learning is critical for the sustainable deployment of AI in dynamic environments.
This research addresses a fundamental limitation in AI's ability to learn continuously without catastrophic forgetting, which is crucial for applications requiring ongoing adaptation and efficiency. Overcoming this challenge expands the practical possibilities for AI agents and general-purpose AI systems.
The proposed bidirectional alignment method offers a more stable and less biased approach to class-incremental learning without needing to store past data, potentially leading to more robust and efficient continuous learning AI systems. This improves the ability of AI models to adapt in real-time without extensive re-training from scratch.
