• Abstract summary: The Train-Attention-Augmented Language Model (TAALM) enhances learning efficiency by dynamically predicting and applying weights to tokens based on their usefulness. We show that TAALM proves the state-of-the-art performance upon the baselines, and also shows synergistic compatibility when integrated with previous CKL approaches.

• Abstract: Previous studies on continual knowledge learning (CKL) in large language models (LLMs) have predominantly focused on approaches such as regularization, architectural modifications, and rehearsal techniques to mitigate catastrophic forgetting. However, these methods naively inherit the inefficiencies of standard training procedures, indiscriminately applying uniform weight across all tokens, which can lead to unnecessary parameter updates and increased forgetting. To address these shortcomings, we propose a novel CKL approach termed Train-Attention-Augmented Language Model (TAALM), which enhances learning efficiency by dynamically predicting and applying weights to tokens based on their usefulness. This method employs a meta-learning framework that optimizes token importance predictions, facilitating targeted knowledge updates and minimizing forgetting. Also, we observe that existing benchmarks do not clearly exhibit the trade-off between learning and retaining, therefore we propose a new benchmark, \textsc{LAMA-ckl}, to address this issue. Through experiments conducted on both newly introduced and established CKL benchmarks, TAALM proves the state-of-the-art performance upon the baselines, and also shows synergistic compatibility when integrated with previous CKL approaches.

  Existing methods often rely on additional reference data, isolated components for distribution or domain predictions. We propose Dynamic Rank-Selective Low Rank Adaptation (LoRA), a universal and efficient continual learning approach. Our approach continually enhances the pre-trained VLM by retaining both the pre-trained knowledge and the knowledge acquired during CL.

  A crucial capability of Machine Learning models in real-world applications is the ability to continuously learn new tasks. In Continual Learning settings, models often struggle to balance learning new tasks with retaining previous knowledge. We propose new learning objectives that integrate the regularization effects of multiple previous posterior estimations.

  Continual learning (CL) refers to the ability to continually learn over time by accommodating new knowledge while retaining previously learned experience. Current machine learning methods are highly prone to overwrite previously learned patterns and thus forget past experience. Since hand-crafting effective update mechanisms is difficult, we propose meta-learning a transformer-based to enhance CL.

For the first time, we revisit the CLIP and CoOp with our method to effectively improve the model on few-shot image classficiation scenario.
