We validate the system through a user study where twenty two people, including undergraduates, graduates and faculty, used CenceMe continuously over a three week period in a campus town. The correct selection of performance metrics is one of the most key issues in evaluating classifier's performance. From this perspective, BNS was the top single choice for all goals except precision, for which Information Gain yielded the best result most often. Experimental results demonstrate that the proposed algorithm exhibits superior performance compared with the existing algorithms on JAFFE, CK+, and BU-3DFE datasets. Based on definitions, We first classify seven most widely performance metrics into three groups, namely threshold metrics, rank metrics, and probability metrics.

Everyday low prices and free delivery on eligible orders. Experimental results on a range of datasets show that our framework can improve duplicate detection accuracy over traditional techniques. A person seeking someone else's attention is normally able to quickly assess how interruptible they are. Experimental results show the reasonableness of classifying seven common used metrics into three groups. "... A person seeking someone else's attention is normally able to quickly assess how interruptible they are. "... Computers understand very little of the meaning of human language. In this work, algorithms are developed and evaluated to detect physical activities from data acquired using five small biaxial accelerometers worn simultaneously on different parts of the body. Although many performance metrics have been proposed in machine learning community, no general guidelines are available among practitioners regarding which metric to be selected for evaluating a classifier's performance. Based on these simulated sensors, we construct statistical models predicting human interruptibility and compare their predictions with the collected self-report data. This assessment allows for behavior we perceive as natural, socially appropriate, or simply polite. We report performance measurements that characterize the computational requirements of the software and the energy consumption of the CenceMe phone client. "...

In this paper, we present a framework for improving duplicate detection using trainable measures of textual similarity. In text domains, effective feature selection is essential to make the learning task efficient and more accurate. 31, No. … There are currently three broad classes of VSMs, based on term–document, word–context, and pair–pattern matrices, yielding three classes of applications. This can be useful for helping practitioners enhance understanding about the different relationships and groupings among the performance metrics. Our goal in this survey is to show the breadth of applications of VSMs for semantics, to provide a new perspective on VSMs for those who are already familiar with the area, and to provide pointers into the literature for those who are less familiar with the field. At the same time, weighting the MB-LBPUH feature can remove the data unbalance from a fusion feature. Recently, the volume of XML documents keeps explosively increasing in various kinds of web applications. Large open source developments are burdened by the rate at which new bug reports appear in the bug repository. The machine scores were validated against a “gold standard” of ratings, that is, those assigned by two human raters. The results show that although some activities are recognized well with subject-independent training data, others appear to require subject-specific training data. However, for essays with widely divergent human ratings, the scoring models were disadvantaged owing to the inherent unreliability of the human scores. Title.
