Line Plot from Scientific Research

Example of the pruning of LCCV. The black dashed line represents threshold value r. The orange dots represent performance observations on the validation set per anchor, and the orange curve is an MMF-model fitted through these points. The blue dots represent performance observations on the train set per anchor, and the blue curve is a fitted MMF model. The dashed green line represents the optimistic extrapolation from the last anchors on the validation curve. If this optimistic extrapolation does not improve over threshold value r, it is unlikely that the learner will actually improve over this value, and the evaluation of the learner can be stopped early.
