Researchers have developed two novel approaches for continual learning in computational pathology, focusing on survival analysis for Whole Slide Images (WSIs). The first, MergeSurv, utilizes a merging-based framework where pathology vision-language foundation models are fine-tuned on individual cancer cohorts and their parameters are sequentially merged. This method, along with its inference strategies One-for-All (OFA) and Voting-Expert Aggregation (VEA), demonstrated superior performance over naive fine-tuning and other continual learning techniques in experiments on TCGA cohorts, effectively mitigating catastrophic forgetting. The second approach benchmarks model merging with test-time adaptation (TTA) for rehearsal-free continual WSI classification. This method shows promise in maintaining task-specific performance and preserving knowledge without storing historical data, though its effectiveness is sensitive to task order and the balance between adaptation and knowledge retention.
