Proposes a theoretical model for analysis of classification methods, in which the teacher knows the classification algorithm and chooses examples in the best way possible. The authors apply this model using the nearest-neighbor learning algorithm, and develop upper and lower bounds on sample complexity for several different concept classes. For some concept classes, the sample complexity turns out to be exponential even using this best-case model, which implies that the concept class is inherently difficult for the NN algorithm. The authors identify several geometric properties that make learning certain concepts relatively easy. Finally the authors discuss the relation of their work to helpful teacher models, its application to decision tree learning algorithms, and some of its implications for experimental work
