Xinran Li, Chenhui Xiang · 2012
Data classification is an important task of data mining, and developing high-powered classification algorithm is one of the key procedures for data mining. This paper provides an improved K-nearest neighbor algorithm-correlation-based K-nearest neighbor algorithm. This new algorithm makes data classification base on the correlation calculation, and uses a modified probability to improve the computational speed and prediction accuracy. The experimental results show that the correlation-based K-nearest neighbor algorithm is more suitable to classify massive high-dimensional data sets while comparing with traditional K-nearest neighbor algorithm.
