    KNN is a straightforward algorithm that stores every single accessible case and characterizes new cases taking into account a similarity or closeness measure. KNN is a non-parametric lazy learning algorithm. By non-parametric technique, it implies that that it does not make any presumptions on the fundamental information appropriation

    classification using nearest neighbors - matlab & simulink

    A default k-nearest neighbor classifier uses a single nearest neighbor only. Often, a classifier is more robust with more neighbors than that. Change the neighborhood size of Mdl to 4, meaning that Mdl classifies using the four nearest neighbors

    Jul 02, 2012 · The default behavior is to use majority rule. That is, a sample point is assigned to the class the majority of the k nearest neighbors are from. Use 'consensus' to require a consensus, as opposed to majority rule. When using the 'consensus' option, points where not all of the k nearest neighbors are from the same class are not assigned to one of the classes
