knn classifier means

May 27, 2020 · KNN classifies the new data points based on the s imilarity measure of the earlier stored data points. For example, if we have a dataset of tomatoes and bananas. KNN will store similar measures like shape and color. When a new object comes it will check its similarity with the color (red or …

    Jun 18, 2020 · K-Nearest Neighbor or K-NN is a Supervised Non-linear classification algorithm. K-NN is a Non-parametric algorithm i.e it doesn’t make any assumption about underlying data or its distribution. It is one of the simplest and widely used algorithm which depends on it’s k value(Neighbors) and finds it’s applications in many industries like finance industry, healthcare industry etc
