Understanding the Answer
Let's break down why this is correct
Answer
The statement is incorrect. A loss function measures how far a prediction is from the true value and is used to guide the training of a model, not just to evaluate accuracy. By assigning different penalties to different kinds of errors, the loss function can encode the cost of mistakes—for example, giving a larger penalty for misclassifying a malignant tumor than a benign one. During training, the algorithm adjusts its parameters to minimize this loss, effectively learning which mistakes are most expensive. So, loss functions are central to both evaluating performance and steering learning toward the most important errors.
Detailed Explanation
A loss function measures how far a prediction is from the true value. Other options are incorrect because The misconception is that loss functions only count wrong guesses.
