While they carry much information, it becomes more and more difficult to manually process it. Our work represents small steps towards automatic knowledge extraction from medical documents using deep learning and similarity based methods. Our goal here is to identify in an unsupervised manner relations between known medical concepts employing a deep learning strategy with Word2Vec. The current solution requires concepts annotations, as it evaluates the similarities between concepts to identify the relationship between them. The experiments suggest that the strategy we considered (to include the POS as part of the information associated to concepts and relation) represents an important step towards a fully unsupervised learning strategy. Although the POS tags alone are not good enough predictors, the addition of other meta-information and sufficient (quantitative and qualitative) training data may enhance the relation identification process, allowing for a meta learning strategy.","PeriodicalId":343658,"journal":{"name":"2016 IEEE 12th International Conference on Intelligent Computer Communication and Processing (ICCP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133291405","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 work, a solution is proposed to support the student's assessment process in physical education classes, through the use of accelerometry data collected from smartphones. This solution aims to deliver accurate and readily available information regarding student's activity using common technologies in order to develop a low-cost approach. To develop this solution, accelerometry data was collected from several students while performing a list of activities, using a smartphone and a developed mobile app. The collected accelerometry data is used for activity information extraction such as energy expenditure and activity recognition. This information is displayed in a developed web application along with analytic charts and student information. The student accelerometry data is summarized and made available as a means to aid and complement the teacher's assessment process and grading system. By engaging the students in the new class assessment system, the authors also hope to promote the practice of healthy exercise habits, by providing the students with visual information about their activity and allowing them to compare statistics between each other and, perhaps more importantly, evaluate their own evolution.","PeriodicalId":343658,"journal":{"name":"2016 IEEE 12th International Conference on Intelligent Computer Communication and Processing (ICCP)","volume":"3 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113971981","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}

Due to its running time and quality performance in real situations the semi global matching algorithm is often used. The biggest disadvantage of the semi global approach is its large memory footprint. On the other hand, block matching stereo is leaner when it comes to memory consumption and therefore it is commonly used in applications where we do not have many resources, in order to obtain coarse depth information of the environment. The poor quality performance of such algorithms make them impractical for many real life applications. In this paper we focus on improving the quality of the classical block matching (BM) stereo method by proposing a novel approach which tackles the problem of stereo matching for slanted and fronto-parallel surfaces by using different types of binary masks on the matching window. Another improvement consists in the usage of different types of local constraints in the generation of the winning disparity for a specific position, such that possible outliers are eliminated from the start. The validation of our results has been done on the KITTI stereo benchmark dataset.","PeriodicalId":343658,"journal":{"name":"2016 IEEE 12th International Conference on Intelligent Computer Communication and Processing (ICCP)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128313299","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}

Classic examples of networks include transport networks, the immune system, human brain and social networks. Given a certain grouping of nodes into communities, a good measure is needed to evaluate the quality of the community structure based on the definition that a strong community has dense intra-connections and sparse outside community links. This paper investigates several fitness functions in an evolutionary approach to community detection in complex networks. Moreover, these fitness functions are used to study dynamic networks using an extended evolutionary algorithm designed to handle changes in the network structure. Computational experiments are performed for several real-world networks which have a known community structure and thus can be evaluated. The obtained results confirm the ability of the proposed method to efficiently detect communities for both static and dynamic complex networks.","PeriodicalId":343658,"journal":{"name":"2016 IEEE 12th International Conference on Intelligent Computer Communication and Processing (ICCP)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126170958","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}

The input data for the algorithm is gathered from a stereo camera and is processed as a disparity image. Each column of the disparity image is segmented based on its relative extreme points. The idea is inspired from a time series compression article which presents a method for segmenting data measured at equal intervals of time (time series): electro cardiograms, monthly stocking-exchanges, etc. The novelty of the method consists in adapting an idea used in a different area of interest for an image recognition purpose. Compared to existing algorithms in the driving assistance field that share the same goal, the proposed method achieves great adaptability and a linear time performance. The adaptability of the method is worth mentioning as it gives good results both on precise data gathered with a lidar scanner and on noisy disparity inferred with a stereo camera. The algorithm filters most of the errors of measurement while preserving the points of interest that delimit the road, objects or sky. Because the filtering steps preserve the data of interest, additional post-processing steps are no longer required thus minimizing the time complexity.","PeriodicalId":343658,"journal":{"name":"2016 IEEE 12th International Conference on Intelligent Computer Communication and Processing (ICCP)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123467614","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}
