• Authors: Jieren Deng and Jianhua Hu and Haojian Zhang and Yunkuan Wang
• Abstract summary: Class incremental learning has attracted much attention, but most existing works still continually fine-tune the representation model. We take the pre-train-and-prompt-tuning paradigm to sequentially learn new visual concepts based on a fixed semantic rich pre-trained representation model. Our method consistently outperforms other state-of-the-art methods with a large margin.

• Abstract: Class incremental learning has attracted much attention, but most existing works still continually fine-tune the representation model, resulting in much catastrophic forgetting. Instead of struggling to fight against such forgetting by replaying or distillation like most of the existing methods, we take the pre-train-and-prompt-tuning paradigm to sequentially learn new visual concepts based on a fixed semantic rich pre-trained representation model by incremental prototype prompt-tuning (IPP), which substantially reduces the catastrophic forgetting. In addition, an example prototype classification is proposed to compensate for semantic drift, the problem caused by learning bias at different phases. Extensive experiments conducted on the three incremental learning benchmarks demonstrate that our method consistently outperforms other state-of-the-art methods with a large margin.

  Class-incremental learning (CIL) aims to enable models to continuously learn new classes while overcoming catastrophic forgetting. In this paper, we revisit different parameter-efficient tuning (PET) methods within the context of continual learning. We observe that adapter tuning demonstrates superiority over prompt-based methods, even without parameter expansion in each learning session.

  We propose a novel method that improves classification robustness by identifying a better embedding space using an improved contrasting loss. Our approach retains previously acquired knowledge in the embedding space, even when trained with new classes. We demonstrate the effectiveness of our method by showing that the embedding space remains intact after training the model with new classes and outperforms existing state-of-the-art algorithms in terms of accuracy across different sessions.

• Contrastive Learning for Fair Representations [50.95604482330149]
  Trained classification models can unintentionally lead to biased representations and predictions. Existing debiasing methods for classification models, such as adversarial training, are often expensive to train and difficult to optimise. We propose a method for mitigating bias by incorporating contrastive learning, in which instances sharing the same class label are encouraged to have similar representations.

We then show that adding a regularization that preserves pretraining weights is effective in mitigating this destructive tendency of few-shot finetuning.

Experiments on three benchmark datasets demonstrate the above-par incremental performance, outperforming state-of-the-art methods by a margin of 13%, 17% and 11%, respectively.
