When evaluating what a fitting curve typically shows in machine learning concepts, we should consider what is most directly related to how models fit data.
Option 1: Generalization performance vs. model complexity. This aligns with the classic bias-variance tradeoff idea, where increasing model complexity can improve fit to training data up to a point but may harm generalization performance on unseen data. It is the standard way to visualize how well a model generalizes as we vary complexity.
Option 2: True positive rate vs. false negative rate. This pair represents a specific performance trade-off related to classification thresholds but is not typically described as a fitting curve; it’s more about how the classifier behaves as you move the decision boundary.
Option 3: True positive rate vs. false positive rate. This is the ROC curve, which plots TPR against FPR to assess discrimination ability across thresholds. While informative about performance, it is not a fitting curve showing generalization with respect to model fitting.
Option 4: Generalization performance vs. size of training set. This describes a learning curve, which shows how performance improves as more training data are provided, not how a model fits as complexity changes. While related to generalization, it’s conceptually distinct from a fitting curve that varies complexity.
Thus, the statement best describing a fitting curve is the one plotting generalization performance against model complexity, since it directly reflects how model suitability changes with added capacity to fit the data.
