What is Instruction Tuning?
Instruction tuning is a supervised fine-tuning method that enhances a model’s ability to understand and follow instructions, improving task-specific performance through labeled examples and clear guidelines.
Definition and Core Concepts
Instruction tuning is a form of supervised fine-tuning that focuses on optimizing a model’s ability to understand and execute specific tasks through clear instructions. It involves training the model on labeled examples that demonstrate how to perform a task, enabling it to generalize and apply the learned patterns to new, unseen instructions. Core concepts include task-specific optimization, the use of labeled data, and the emphasis on explicit guidance to improve performance. Unlike prompt tuning, instruction tuning requires additional training data and is particularly effective in scenarios where clear directives are essential for achieving desired outcomes.
How Instruction Tuning Works
Instruction tuning involves training a model to understand and execute specific tasks by providing it with labeled examples of instructions and corresponding outputs. The model learns to map instructions to desired responses by adjusting its parameters during the fine-tuning process. This approach leverages supervised learning, where the model optimizes its performance based on explicit guidance from the training data. Unlike prompt tuning, instruction tuning requires retraining the model on task-specific datasets, enabling it to generalize and apply learned patterns to new instructions effectively.
Supervised Fine-Tuning in Instruction Tuning
Supervised fine-tuning in instruction tuning involves training a model using labeled datasets where each example includes an instruction and its corresponding expected output. The model learns to align its responses with the provided examples by optimizing its parameters to minimize errors. This approach requires explicit supervision, making it resource-intensive but highly effective for adapting models to specific tasks. Unlike prompt tuning, which relies on carefully crafted inputs, supervised fine-tuning directly updates the model’s weights, enabling better task-specific performance at the cost of computational resources and flexibility.
