• Abstract summary: Continual learning is essential for keeping Large Language Models current and addressing their shortcomings. We propose the Continue Evolving from Mistakes (CEM) method, a data-efficient approach aiming to collect CPT data. Experiments show that CEM substantially enhances multiple models' performance on both in-domain and out-of-domain QA tasks, achieving gains of up to 29.63%.

• Abstract: As world knowledge advances and new task schemas emerge, Continual Learning (CL) becomes essential for keeping Large Language Models (LLMs) current and addressing their shortcomings. This process typically involves continual instruction tuning (CIT) and continual pre-training (CPT) to enable these models to adapt to novel tasks and acquire critical knowledge. However, collecting sufficient CPT data and efficiently bridging knowledge gaps remain significant challenges. Inspired by the 'summarizing mistakes' strategy, we propose the Continue Evolving from Mistakes (CEM) method, a data-efficient approach aiming to collect CPT data and continually improve LLMs' performance through iterative evaluation and supplementation with mistake-relevant knowledge. To further optimize data usage and mitigate forgetting, we introduce a novel training paradigm that combines CIT and CPT. Experiments show that CEM substantially enhances multiple models' performance on both in-domain and out-of-domain QA tasks, achieving gains of up to 29.63%.

  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.
