Role of the Loss Function in Model Fine-Tuning
An engineer is fine-tuning a large language model to predict the 'readability score' of a given paragraph, where the score is a continuous value from 1 to 100. Describe the fundamental role of a regression loss function in this training process. How does the value calculated by this function guide the model to make more accurate predictions over time?

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?
