The AREA framework enhances CLIP-based Class-Incremental Learning by decomposing the classification process into attribute extraction and attribute aggregation, developing methods to stabilize both. This approach effectively mitigates catastrophic forgetting, yielding substantial performance gains across nine benchmark datasets.
Key insights
- CLIP-based classification can be mechanistically decomposed into distinct attribute extraction and aggregation stages, both of which are critical sources of catastrophic forgetting in CIL.
- Stabilizing class-level multi-modal attribute representations through geometry-aware anchoring (PGA) is crucial for consistently recognizing old classes as new ones are learned.
- Regularizing attribute aggregation with an information bottleneck ensures models focus on genuinely discriminative, label-relevant features, avoiding task-specific shortcuts and noise.
