The NEFTune method is proposed as a way to improve the performance of language models on instruction-based tasks. By adding random noise to the embedding vectors during fine-tuning, the model’s performance is significantly enhanced without needing more computational resources or data. This approach leads to better conversational abilities without sacrificing factual question-answering performance. NEFTune has the potential to be widely used in developing language models for various real-world tasks.
Revolutionizing Language Model Fine-Tuning: Achieving Unprecedented Gains with NEFTune’s Noisy Embeddings
Instruction fine-tuning is a crucial process in training language models to perform well on instruction-based tasks. It offers benefits like better interpretability, reduced bias, and improved task performance. To enhance the outcome of this process, researchers have introduced NEFTune, a new method that significantly improves model performance without requiring extra computational resources or additional data.
NEFTune involves adding random noise to the embedding vectors of training data during fine-tuning. This method has shown surprising improvements in the performance of language models on conversational tasks while maintaining factual question-answering performance.
The researchers conducted experiments using 7B parameter language models like LLaMA-1, LLaMA-2, and OPT-6.7B, and fine-tuning datasets like Alpaca and ShareGPT. The results were evaluated using the AplacaEval dataset, showing a significant increase in conversational ability and answer quality. For example, the performance of LLaMA-2 7B increased from 29.8% to 64.7% when fine-tuned with noisy embeddings.
NEFT was preferred by human annotators in 88 instances, with 22 instances resulting in a draw, indicating a win score of around 74% for NEFT. The method also demonstrated clearer explanations of complex topics like quantum computing.
NEFTune is a promising tool for enhancing the capabilities of language models on real-world tasks. It does not require additional computational resources, making it a cost-effective solution for middle managers looking to leverage AI in their companies.
