Quantum walk for k-nearest neighbor

WebEnter the email address you signed up with and we'll email you a reset link. WebThe K-nearest neighbor (KNN) classifier is one of the simplest and most common classifiers, yet its performance competes with the most complex classifiers in the literature. The core of this classifier depends mainly on measuring the distance or similarity between the tested examples and the training examples.
