Training BERT-based Regression Models via Loss Minimization
The standard procedure for training or fine-tuning a BERT-based model for a regression task is to optimize its parameters by minimizing a regression loss function. This loss function quantifies the error between the model's predicted continuous value and the actual ground-truth score.

Adapting a Language Model for a New Task
A data science team has a pre-trained transformer model that has been successfully fine-tuned for a text classification task, predicting whether a product review is 'positive' or 'negative'. They now want to adapt this model for a new regression task: predicting a continuous 'star rating' for reviews, on a scale from 1.0 to 5.0. Which of the following modifications represents the most direct and essential change to the model's architecture to enable this new task?

A data scientist is fine-tuning a model to predict a 'user engagement score' (a continuous value from 0.0 to 1.0) for online articles. During an early training step, the model processes two articles:
- Article A has an actual score of 0.9, but the model predicts 0.4.
- Article B has an actual score of 0.2, but the model predicts 0.5.
Assuming a standard regression loss function is used to quantify the error, what is the immediate objective of the optimization step that follows this calculation?
