This paper proposes an end-to-end deep hashing framework with category mask for fast video retrieval. We train our network in a supervised way by fully exploiting interclass diversity and intra-class identity. Classification loss is optimized to maximize inter-class diversity, while intra-pair is introduced to learn representative intra-class identity. We investigate the binary bits distributio...

IN practice, intra-ocular tumours are vaguely classified as gliomata if they originate in the retina, or as melanomata if they have originated in the choroid and contain brown pigment that does not give the iron reaction. Those attempting greater precision place most of the gliomata in the more restricted group of retinoblastomata. The problem, however, is not so simple, for on closer examinati...

Feature selection is a critical task in both sentiment classification and topical text classification. However, most existing feature selection algorithms ignore a significant contextual difference between them that sentiment classification is commonly depended more on the words conveying sentiments. Based on this observation, a new feature selection method based on matrix factorization is prop...

Our aim was to assess the reproducibility and the reliability of the Weber classification system for fractures of the ankle based on anteroposterior and lateral radiographs. Five observers with varying clinical experience reviewed 50 sets of blinded radiographs. The same observers reviewed the same radiographs again after an interval of four weeks. Inter- and intra-observer agreement was assess...

INTRODUCTION Starting with a vast number of unstructured or semi-structured documents, text mining tools analyze and sift through them to present to users more valuable information specific to their information needs. The technologies in text mining include information extrac-In this chapter, we share our hands-on experience with one specific text mining task — text classification [Sebastiani, ...

background: research supports that in vitro fertilization causes anxiety and that anxiety can continue into the resulting pregnancy. most women who have ivf will have a less invasive treatment for infertility prior to ivf; however, it is unclear if specific less invasive treatment cycles impact anxiety that is experienced in the pregnancy resulting from ivf. methods: a prospective study was con...
