WebMar 17, 2024 · We’ll now declare a class called KNN having the Scikit-Learn API syntax in mind. The class will have the following methods: __init__ (k) – the constructor, stores the value for the number of neighbors (default is 3) and for the training data, which is initially set to None. _euclidean_distance (p, q) – implements the formula from above. WebOct 19, 2024 · KNN is an acronym for K-Nearest Neighbor. It is a Supervised machine learning algorithm. KNN is basically used for classification as well as regression. KNN does not assume any underlying parameters i.e. it is a non-parametric algorithm. Steps followed by KNN algorithm It initially stores the training data into the environment.
