Research and Implementation of Machine Learning Classifier Based on KNN

Abstract Machine learning classifier is an important part of pattern recognition system; it is also an important research field of machine learning. The main research object of this paper is K data mining (KNN, K Nearest Neighbor) classification method, using KNN to classify the data, and compare the classification results. The research work of this paper mainly discusses the implementation of KNN-based machine learning classifier, mainly focusing on the theoretical analysis of K-data mining, algorithm implementation, and implementing KNN-based machine learning classifier.
