• Abstract: Few-shot class-incremental learning(FSCIL) focuses on designing learning algorithms that can continually learn a sequence of new tasks from a few samples without forgetting old ones. The difficulties are that training on a sequence of limited data from new tasks leads to severe overfitting issues and causes the well-known catastrophic forgetting problem. Existing researches mainly utilize the image information, such as storing the image knowledge of previous tasks or limiting classifiers updating. However, they ignore analyzing the informative and less noisy text information of class labels. In this work, we propose leveraging the label-text information by adopting the memory prompt. The memory prompt can learn new data sequentially, and meanwhile store the previous knowledge. Furthermore, to optimize the memory prompt without undermining the stored knowledge, we propose a stimulation-based training strategy. It optimizes the memory prompt depending on the image embedding stimulation, which is the distribution of the image embedding elements. Experiments show that our proposed method outperforms all prior state-of-the-art approaches, significantly mitigating the catastrophic forgetting and overfitting problems.

  In continual learning, previous knowledge is forgotten when a model learns new tasks. In this paper, we tried to solve this problem by acquiring transferable knowledge through self-distillation. Our proposed method outperformed conventional methods by experiments on CIFAR10, CIFAR100, and MiniimageNet datasets.

  Existing lifelong event detection methods typically maintain a memory module and replay the stored memory data during the learning of a new task. The simple combination of memory data and new-task samples can still result in substantial forgetting of previously acquired knowledge. We propose a novel method based on embedding space separation and compaction.

  We study class-incremental learning, a training setup in which new classes of data are observed over time for the model to learn from. Despite the straightforward problem formulation, the naive application of classification models to class-incremental learning results in the "catastrophic forgetting" of previously seen classes. One of the most successful existing methods has been the use of a memory of exemplars, which overcomes the issue of catastrophic forgetting by saving a subset of past data into a memory bank and utilizing it to prevent forgetting when training future tasks.

• Learning to Rehearse in Long Sequence Memorization [107.14601197043308]
  Existing reasoning tasks often have an important assumption that the input contents can be always accessed while reasoning. Memory augmented neural networks introduce a human-like write-read memory to compress and memorize the long input sequence in one pass. But they have two serious drawbacks: 1) they continually update the memory from current information and inevitably forget the early contents; 2) they do not distinguish what information is important and treat all contents equally. We propose the Rehearsal Memory to enhance long-sequence memorization by self-supervised rehearsal with a history sampler.
