There are no pre-defined statistical methods to find the most favourable value of K. Choosing a very small value of K leads to unstable decision boundaries. Value of K can be selected as k = sqrt (n). where n = number of data points in training data Odd number is preferred as K value. Most of the time below approach is followed in industry.The base algorithm uses Euclidean distance to find the nearest K (with K being our hyperparameter) training set vectors, or “neighbors,” for each row in the test set.
