一类基于非线性PCA和深度置信网络的混合分类器及其在PM2.5浓度预测和影响因素诊断中的应用
A Kind of Deep Belief Networks Based on Nonlinear Features Extraction with Application to PM2.5 Concentration Prediction and Diagnosis
摘要
Abstract
To build a classifier model of high dimensional data,the traditional deep brief networks (DBN) modeling method suffers from large network load and high algorithm complexity.In this work,the data dimension is reduced based on the nonlinear PCA (NPCA),then a new DBN classifier with nonlinear feature extraction pre-processing mechanism is proposed where the nonlinear feature is extracted as the network input to the DBN.With the entropy theory,the advantage of the improved DBN is proved in terms of network structure and algorithm complexity.A PM2.5 concentration prediction and diagnosis problem is employed to exemplify applications of the proposed methods.Compared with the traditional classifier,it shows the advantage of the proposed method in modeling accuracy and convergence speed.关键词
