://blog.sciencenet.cn/blog-460603-785098.htmlClassification is an important data mining algorithm. The purpose of classification is to construct a classification function or a classification model (i.e., a classifier) that maps data objects to a given category through a classifier. The main evaluation indexes of classifier are accuracy rate (Precision), recall rate (Recall),Fb-score, ROC, AOC and so on. In the study, accuracy (correct rate) was used t

dimensionality reduction techniques. Of course, the final accuracy and loss rate is also related to the selected data analysis model. Therefore, the final dimensionality reduction rate and the accuracy of the comparison is carried out in three models, the three models are: Decision tree, neural network and naive Bayesian.By running an optimized cycle, the optimal cycle termination means that low latitude and high accuracy depend on the seven dimensionality reduction methods and the best classif
