WebMar 4, 2024 · $\begingroup$ Ah, yes, you are applying cross_val_score incorrectly. That function splits into folds, trains the model and predicts for each train/test split. Running it on your (trainX, trainY) gives the test-fold average score, and running it on your (testX, testY) again gives a test-fold average, with models trained on subsets of testX now.

WebNov 14, 2024 · The principle behind nearest neighbor classification consists in finding a predefined number, i.e. the ‘k’ — of training samples closest in distance to a new sample, which has to be classified. The label of the new sample will be defined from these neighbors. k-nearest neighbor classifiers have a fixed user defined constant for the number ...
