Question

I’m completely new to the k-nearest neighbor classifier algorithm. Can someone please give me a link to a good tutorial/lecture that gives a dataset so that I can apply k-nearest neighbor to it.

I really really need to learn this but due to lack of examples it’s making this task very difficult.

Answer 1

I recommend the Iris plant dataset.

This is perhaps the best known database to be found in the pattern recognition literature. Fisher’s paper is a classic in the field and is referenced frequently to this day. (See Duda & Hart, for example.) The data set contains 3 classes of 50 instances each, where each class refers to a type of iris plant. One class is linearly separable from the other 2; the latter are NOT linearly separable from each other.
