• Authors: Kai Wang, Luis Herranz, Anjan Dutta, Joost van de Weijer
• Abstract summary: We propose a flexible setting where unseen classes can be inferred via a semantic model, and the visual model can be updated continually. We also propose the bidirectional imagination (BImag) framework to address BCL where features of both past and future classes are generated.

• Abstract: We propose bookworm continual learning(BCL), a flexible setting where unseen classes can be inferred via a semantic model, and the visual model can be updated continually. Thus BCL generalizes both continual learning (CL) and zero-shot learning (ZSL). We also propose the bidirectional imagination (BImag) framework to address BCL where features of both past and future classes are generated. We observe that conditioning the feature generator on attributes can actually harm the continual learning ability, and propose two variants (joint class-attribute conditioning and asymmetric generation) to alleviate this problem.

  We present a parameter-efficient continual learning framework to alleviate long-term forgetting in incremental learning with vision-language models. Our approach involves the dynamic expansion of a pre-trained CLIP model, through the integration of Mixture-of-Experts (MoE) adapters. To preserve the zero-shot recognition capability of vision-language models, we introduce a Distribution Discriminative Auto-Selector.

  Zero-shot learning (ZSL) is a promising approach to generalizing a model to unseen categories during training. We propose a Meta-learned Attribute self-Interaction Network (MAIN) for continual ZSL. By pairing attribute self-interaction trained using meta-learning with inverse regularization of the attribute encoder, we are able to outperform state-of-the-art results without leveraging the unseen class attributes.

  We address the challenge of continual zero-shot learning where unseen information is not provided during training, by leveraging generative modeling. We propose our learning algorithm that employs a novel semantically guided Generative Random Walk (GRW) loss. Our algorithm achieves state-of-the-art performance on AWA1, AWA2, CUB, and SUN datasets, surpassing existing CZSL methods by 3-7%.

  Continual Learning (CL) is a flavor of machine learning where the usual assumption of stationary data distribution is relaxed or omitted. Changes in the data distribution can cause the so-called catastrophic forgetting (CF) effect: an abrupt loss of previous knowledge. This article reviews literature that study CL in other settings, such as learning with reduced supervision, fully unsupervised learning, and reinforcement learning.

  We introduce a novel mechanism that dynamically augments during training the set of seen classes to produce additional fictitious classes. These fictitious classes diminish the model's tendency to fixate during training on attribute correlations that appear in the training set but will not appear in newly exposed classes.
