In unsupervised learning, an unbiased uniform sampling strategy is typically used, in order that the learned features faithfully encode the statistical structure of the training data. In this work, we explore whether active example selection strategies — algorithms that select which examples to use, based on the current estimate of the features — can accelerate learning. Specifically, we invest...

xml is a language for describing markup languages for structured data. A growing number of applications that process xml documents are transformers, i.e., programs that convert documents between xml languages. Unfortunately, the current proposals for transformers are complex general-purpose languages, which will be unappealing as the xml user base broadens and thus decreases in technical sophis...

the purpose of the study was to verify, through the use of an experimental method, the assumption that the ‘economic human’ pays more attention to the externality he/she causes as the strength of externality increases. we used a social-experiment design within an undergraduate classroom to test assumptions, using statistical method. a lakeside plant was used as an example. our results confirmed...

the radio magnetotelluric (rmt) method is one of the most widely used electromagnetic (em) methods which employs artificial time varying electric and magnetic fields at the surface of the earth for imaging conductivity. the radiomagnetotelluric method proposed by goldstein and strangway (1975) is based on measuring one set of horizontal electrical and perpendicular magnetic components. after th...

In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...
