They optimize the computational resources used in prediction.
D
They define the structure of the predictor function.
Understanding the Answer
Let's break down why this is correct
Answer
Loss functions measure how far a model’s predictions are from the true values; they give the model a numerical score to improve. During training the model adjusts its parameters to reduce this score, which means it learns to make predictions that are closer to the actual data. The shape and scale of the loss function influence which errors are penalized more heavily and guide the optimization process. For example, if a loss function heavily penalizes large mistakes, the model will focus on reducing those large errors first. Thus, the loss function is the core signal that tells the model how well it is doing and how it should change.
Detailed Explanation
Loss functions give a number that shows how far predictions are from the real values. Other options are incorrect because Some think loss functions decide how complex a model is; Others believe loss functions manage how fast or memory‑efficient a model is.
