Key Concepts in Supervised Fine-Tuning for Hyperparameter Tuning

Supervised fine-tuning is a process where a pre-trained model is further trained on a labeled dataset to adapt it to a specific task. In the context of hyperparameter tuning, this involves systematically adjusting hyperparameters to optimize model performance. Key concepts include:

• Hyperparameters: Parameters such as learning rate, batch size, and number of epochs that are set before training begins.
• Fine-Tuning: Refining a pre-trained model to improve its performance on a specific task.
• Supervised Learning: A machine learning paradigm where models learn from labeled data.
• Grid Search and Random Search: Traditional methods for hyperparameter tuning that involve exhaustive or random exploration of parameter combinations.
• Bayesian Optimization: A probabilistic approach to hyperparameter tuning that models the performance of hyperparameters as a function and optimizes it.

Understanding these concepts is crucial for leveraging supervised fine-tuning effectively in hyperparameter tuning.
