In this paper, we show that we can obtain a good baseline performance for Question Answering (QA) by using only 4 simple features. Using these features, we contrast two approaches used for a Maximum Entropy based QA system. We view the QA problem as a classification problem and as a reranking problem. Our results indicate that the QA system viewed as a reranker clearly outperforms the QA system...

Social networking sites, such as Facebook, have gained immense popularity as communication platforms and as advertising tools. Generation Yers have a strong need to engage with others and make connections-digitally and in person. This paper examines the Facebook behavior of Generation Y by means of a self-administered survey of 383 university students. The purpose of this research was to determ...

The aim in this paper is to show how to use the 2.5D facial surface normals (needle-maps) recovered using shape from shading (SFS) to improve the performance of gender classification. We incorporate principal geodesic analysis (PGA) into SFS to guarantee the recovered needle-maps is a possible example defined by a statistical model. Because the recovered facial needlemaps satisfy data-closeness...

this presentation analyses the histological types, relative incidences, age, sex and anatomical distributions of one hundred and seventy-nine biopsy proven tumors of the spinal canal from a general hospital in iran. particular attention is paid to differences in the relative incidence of these tumors compared with that in various published reports and the statistics from several eastern countri...

An efficient approach to recognize the parameter of weighted-type fractional Fourier transform signals based on higher-order cumulant is proposed. Due index additivity transform, statistical features different weighted domains could be jointly considered, overcome problem ambiguity arising from existing estimation methods cumulant. This method can improve ability blind signal recognition no mat...
