Overview
- Study comparing supervised fine-tuning (SFT) and reinforcement learning (RL) approaches for training foundation models
- Shows RL leads to better generalization while SFT tends toward memorization
- Analyzes performance across various tasks including reasoning and open-ended generation
- Demonstrates key differences in how models learn from these training methods
Plain English Explanation
Foundation models like GPT-4 need additional training after their initial creation to perform specific tasks well. This paper examines two main approaches: supervised fine-tuning, which is like teaching by example, and reinforcement learning, which is more like learning through...
