Optimizing Training Data Allocation Between Supervised and Preference Finetuning in Large Language Models

Introduction

Large Language Models (LLMs) face challenges in improving their training methods, specifically in balancing Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL) techniques. Understanding how to best allocate limited training resources between these approaches is crucial for enhancing performance.

Research Insights

Recent studies indicate that LLMs can achieve better task alignment without extensive SFT, suggesting alternatives to traditional training methods. Given the high costs of human data collection, it is essential to evaluate the efficiency of various training strategies within fixed budgets.

Proposed Study

Researchers from the Georgia Institute of Technology have initiated a comprehensive study to explore the optimal balance of training data budgets between SFT and Preference Fine-Tuning (PFT). This study evaluates multiple tasks, model sizes, and annotation costs, shedding light on the “cold start problem” in mathematical tasks.

Key Findings

The study reveals that even a small allocation of the budget to SFT can significantly enhance performance, particularly in analytical tasks. For example, using 5,000 examples with 25% SFT allocation can match the performance of 20,000 examples with 75% SFT allocation. This indicates that SFT is beneficial in low-data scenarios, while larger budgets can leverage a mix of preference data.

Conclusion

This research provides valuable insights into optimizing LLM post-training under resource constraints, emphasizing the importance of balancing SFT and PFT. While allocating just 10% of the budget to initial SFT can mitigate performance issues, it is important to consider the limitations of current methods and the computational demands of larger models.
