Instruction tuning and prompt tuning are powerful techniques for optimizing large language models (LLMs). Both methods enhance model performance but differ in approach and application. Understanding these techniques is crucial for effective LLM customization and task-specific optimization.
1.1 Definition of Instruction Tuning
Instruction tuning is a technique used to fine-tune large language models (LLMs) by training them on a dataset of instructional prompts and their corresponding responses. This method involves supervised learning, where the model learns to generate outputs that align with specific tasks or guidelines. Unlike prompt tuning, instruction tuning focuses on optimizing the model’s ability to follow instructions and produce accurate, task-oriented responses. It is particularly effective for tasks requiring clear guidance, such as problem-solving or generating step-by-step explanations. By leveraging labeled data, instruction tuning enhances the model’s alignment with human intentions and improves its performance on structured tasks.
1.2 Definition of Prompt Tuning
Prompt tuning is a technique that optimizes large language models (LLMs) by adjusting the input prompts rather than modifying the model’s weights. It involves crafting specific prompts, often using soft prompts or adjustable vectors, to guide the model’s behavior. Unlike instruction tuning, prompt tuning does not require labeled datasets and is more flexible, enabling customization without extensive training. This method is particularly useful for tasks where fine-tuning the model is impractical, such as adapting to new domains or handling rare scenarios. By refining the prompts, prompt tuning enhances the model’s ability to generate desired outputs efficiently and effectively.
