The K-Nearest Neighbor (K-NN) algorithm is one of the simplest methods for solving classification problems; it often yields competitive results and has significant advantages over several other data mining methods.

People in data mining never test with the data they used to train the system. You can see why we don’t use the training data for testing if we consider the nearest neighbor algorithm.
Here, the k-Nearest Neighbor Algorithm Pseudo Code is framed using a function kNN() which takes a single test sample or instance, x as argument and returns a 2-D Vector containing the prediction result as the 1st element and the value of k as the 2nd element.
The “K” is KNN algorithm is the nearest neighbors we wish to take vote from. Let’s say K = 3. Hence, we will now make a circle with BS as center just as big as to enclose only three datapoints on the plane. Refer to following diagram for more details:
Nearest neighbor is a special case of k-nearest neighbor class. Where k value is 1 (k = 1). In this case, new data point target class will be assigned to the 1 Where k value is 1 (k = 1). In this case, new data point target class will be assigned to the 1 st closest neighbor.
A k-nearest-neighbor algorithm, often abbreviated k-nn, is an approach to data classification that estimates how likely a data point is to be a member of one group or the other depending on what group the data points nearest to it are in.
