Various techniques like Magnetic Resonance Imaging (MRI), functional MRI (fMRI), and Positron emission tomography (PET) could be used to enumerate the loss of neurons in different parts of brain. In this paper we present a novel approach for detecting PD using brain MRI scans. Because of non-invasiveness and high resolution property, MRI is preferred over other techniques. For this study, the MRI images (healthy/PD patients) have been collected from Parkinson's Progression Markers Initiative (PPMI) organization. Research efforts have stated that Extreme Learning Machine (ELM) has better and accurate diagnosis ability. In this paper, PD diagnosis based on ELM-based method along with Genetic Algorithm feature subset selection has been proposed. The classifier uses voxel based morphometric features extracted from MRI. Since, the feature extracted are large in number, a feature subset selection technique using Genetic Algorithm is implemented. The performance of GA-ELM method is evaluated using classification accuracy, sensitivity, specificity. The results show that the classification accuracy obtained for ELM model is higher than the one obtained using SVM approach. Also GA-ELM classifier model produces a better generalization performance with high sensitivity and low misclassification rate.","PeriodicalId":354589,"journal":{"name":"2016 Second International Conference on Cognitive Computing and Information Processing (CCIP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129766967","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}

This paper focuses on a novel descriptor which can efficiently re-identify persons in varied views and change in illumination. The descriptors detect the features by dividing the person image into multiple parts. We use a combination of local and global feature descriptors to form a reliable descriptor. Performance evaluation is done on a benchmarking dataset.","PeriodicalId":354589,"journal":{"name":"2016 Second International Conference on Cognitive Computing and Information Processing (CCIP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129030751","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}

In this paper, the Random Forest regression model is used to predict popularity of articles from the Online News Popularity data set. The performance of the Random Forest model is investigated and compared with other models. Impact of standardization, regularization, correlation, high bias/high variance and feature selection on the learning models are also studied. Results indicate that, the Random Forest approach predicts popular/unpopular articles with an accuracy of 88.8%.","PeriodicalId":354589,"journal":{"name":"2016 Second International Conference on Cognitive Computing and Information Processing (CCIP)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125999082","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}
