Understanding the Answer

Let's break down why this is correct

Answer

The choice of loss function does matter in multi‑class classification because it shapes how the model learns to separate classes during training. A loss that heavily penalizes misclassifications (like cross‑entropy) pushes the network to produce sharper probability distributions, while a loss that focuses on ranking (like hinge loss) may favor different decision boundaries. If the loss and the evaluation metric (e. g. , accuracy or F1) are mismatched, the model may optimize for the wrong objective and underperform on the metric you care about.

Detailed Explanation

Choosing the right loss function tells the model how to adjust its weights. Other options are incorrect because Some think that metrics alone can fix a bad loss.
