Fine-Tuning GPT-2 for IMDb Sentiment Analysis | HackerNoon
Briefly

In our experiments, we found that employing the DPO technique consistently yielded better performance in terms of reward maximization compared to traditional methods. This was particularly evident in tasks where sentiment analysis and text summarization were critical, showing DPO's strength in optimizing outputs directly linked to user preferences.
We demonstrated the effectiveness of Direct Preference Optimization (DPO) through rigorous theoretical analysis, revealing that it not only improves performance but also converges faster compared to established reward maximization frameworks. Our findings suggest DPO could be a game-changer in developing models that align closely with human preferences.
