Nevertheless, PLS separates variables insufficiently, thus it cannot provide accurate results in quality-related process monitoring. To make up for this deficiency, in this paper, an improved PLS is described in detail which promotes the performance of PLS based on the coefficient matrix between input and output measurements. According to the detection results of IPLS, the contributions plots of the square of T statistics is calculated to judge the faulty variables of the fault. Taking the Tennessee Eastman (TE) process as a description, it verifies the effectiveness of IPLS in quality-related fault detection and fault diagnosis.","PeriodicalId":6669,"journal":{"name":"2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"27 1","pages":"296-301"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91137466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then the Gaussian probability function is used to convert them into three probability matrices as the three-channel input of convolutional neural network. Finally the targets are divided into three categories: pedestrian, motor vehicle and non-motor vehicle. The experiments are performed with real data collected from different times and different scenarios, the results show that the proposed method can detect targets accurately, and the accuracy can reach 90%.

Based on kernel trick and the improved Fisher discrimination dictionary learning, this paper designs a dictionary learning algorithm that can effectively improve image classification performance. Kernel space transformation can learn non-linear structural information, which is very useful for image classification. The traditional kernel dictionary learning algorithm has high computational complexity, which is not conducive to practical application. We address this problem by proposing a sample preprocessing method based on Nystrom algorithm. By introducing the incoherent promoting terms into the Fisher discrimination dictionary learning model, we can obtain more discriminative coding coefficients while learning a structured dictionary. The effectiveness of the proposed kernel incoherent Fisher discrimination dictionary learning (KIFDDL) method is verified by the results of the classification experiments on several publicly image databases.","PeriodicalId":6669,"journal":{"name":"2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"5 1","pages":"143-148"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81696680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
