This paper studies continual learning (CL) of a sequence of aspect sentiment classification(ASC) tasks in a particular CL setting called domain incremental learning (DIL). Each task is from a different domain or product. The DIL setting is particularly suited to ASC because in testing the system needs not know the task/domain to which the test data belongs. To our knowledge, this setting has not been studied before for ASC. This paper proposes a novel model called CLASSIC. The key novelty is a contrastive continual learning method that enables both knowledge transfer across tasks and knowledge distillation from old tasks to the new task, which eliminates the need for task ids in testing. Experimental results show the high effectiveness of CLASSIC.

  1. IRS: Incremental Relationship-guided Segmentation for Digital Pathology

    eess.IV 2025-05 conditional novelty 5.0 of 10

    IRS uses anatomical relationships between old and new classes to guide knowledge distillation in a prompt-driven mixture-of-experts network, improving class-incremental segmentation of kidney pathology compared to baselines.

  2. Exploring Kolmogorov-Arnold Network Expansions in Vision Transformers for Mitigating Catastrophic Forgetting in Continual Learning

    cs.CV 2025-07 reject novelty 3.0 of 10

    KAN-based ViTs show slight average incremental accuracy gains over MLP-ViTs in continual learning, but the paper's own data show worse forgetting on CIFAR-100 and worse last-task accuracy on MNIST.
