CEM: A Data-Efficient Method for Large Language Models to Continue Evolving From Mistakes
Data-Efficient LLM Evolution from Mistakes
Our analysis reveals the transformative potential of CEM in enabling LLMs to learn continuously and correct errors efficiently.
Executive Impact Summary
The CEM method introduces a novel, data-efficient framework for continuous LLM evolution. It identifies LLM mistakes and uncertainties, collects targeted CPT data, and employs a joint training paradigm leveraging CIT and CPT to assimilate knowledge efficiently while mitigating catastrophic forgetting. Experiments confirm substantial accuracy gains (up to 29.63%) across various models and tasks.

The CEM method introduces an iterative process for continuous LLM evolution. It focuses on mistake identification, targeted data collection, and a novel joint training paradigm that leverages both Continual Instruction Tuning (CIT) and Continual Pre-training (CPT) to efficiently assimilate knowledge while preserving existing capabilities and mitigating catastrophic forgetting.

Max Accuracy Gain on Xiezhi (Llama3-8B-Instruct)
CEM's data acquisition pipeline efficiently collects targeted CPT data directly from LLM errors and uncertainties. The Ambiguity-Aware Knowledge Collection (AAKC) algorithm is key, expanding CPT data by identifying instances where the model expresses uncertainty, going beyond explicit errors. This approach achieves superior data efficiency and targeted knowledge acquisition.

A novel joint training paradigm effectively leverages the complementary strengths of CIT and CPT. It ensures efficient knowledge assimilation while robustly preserving instruction-following and dialogue capabilities against degradation and catastrophic forgetting, enabling iterative, continual model evolution.
Impact of Extractive and Review Instructions
Experiments show that Extractive Instruction (IE) significantly enhances the model's ability to capture and comprehend knowledge, leading to a W2R improvement of up to 3.22%. Review Instruction (IR) substantially reduces the R2W metric, indicating better retention of previously correct knowledge. The combination leads to superior performance and reduced catastrophic forgetting.
