The Application of Machine Learning Algorithms in Data Mining
Based on the two problems regarding data mining, this research puts forward a solution using machine learning algorithm. To begin with, large amount of data for the field test results of mobile terminals are used to receive the level signals so as to realize the positioning of the GSM mobile terminals in outdoor scenario. To solve these problems, this work proposes a three-stage positioning algorithm on the basis of support vector machine (SVM) and a k-nearest neighbor method, which largely improves the accuracy and speed of the positioning.
