Checklist ROAI 2024 County Stage · Task 2
Points Classifier
Romanian title: Problema 2
Learn an unknown axis-parallel rectangle from labelled 2D points in three scenarios with different training-set sizes.
The task
Points (X, Y) with 0 ≤ X, Y ≤ 100 are labelled 1 if they lie inside an unknown axis-parallel rectangle (boundary included) and 0 otherwise. From labelled training points, the contestant must build a classifier for any point of the square.
There are three independent scenarios, each hosted as a Kaggle competition and possibly using a different rectangle: 100, 1,000 and 5,000 training examples, each with 5,000 test examples.
