Fine-Tuning Pre-trained Models for Downstream Tasks

Adapting a pre-trained model for a new task involves combining it with a new prediction network. The subsequent fine-tuning is a standard optimization process that starts by initializing the model with its pre-trained parameters, denoted as θ^\hat{\theta}. The entire model, including the new network's parameters ω\omega, is then trained on a task-specific labeled dataset. This supervised process minimizes a loss function to produce optimized parameters, θ~\tilde{\theta} and ω~\tilde{\omega}, thereby specializing the model for the new task.
