A key challenge in the realization of autonomous vehicles is the machine’s ability to perceive its surrounding environment. This task is tackled through a model that partitions vehicle camera input into distinct semantic classes, by taking into account visual contextual cues. The use of structured machine learning models is investigated, which not only allow for complex input, but also arbitrar...

A Spatio-temporal data model for biodiversity is growing importance to the biodiversity data management, forest and environment control. Spatio-temporal data models have received much attention in the database research community because of their practical importance and interesting challenges they pose. This paper is discussed upon the research activities of selecting, designing, implementing t...

A major challenge in supervised sentence compression is making use of rich feature representations because of very scarce parallel data. We address this problem and present a method to automatically build a compression corpus with hundreds of thousands of instances on which deletion-based algorithms can be trained. In our corpus, the syntactic trees of the compressions are subtrees of their unc...

considering the importance of the impact of subsidy reform on the agricultural sector, the study aimed at understanding consequences of changes in the rates of production subsidy using general equilibrium model based on input-output table in the year 2001.the study conducted based on three scenarios containing step, down and finally removed rates of production subsidy. the effects on production...

We study a structured output learning setting where both the sample size and dimensions of the feature vectors of both the input and output are very large (possibly infinite in the latter case), but the input and output feature representations are nonnegative and very sparse (i.e. the number of nonzero components is finite and their proportion to the dimension is close to zero). Such situations...

A cornerstone of professional education is the practicum, "a setting designed for the task of learning a practice. In a context that approximates a practice world, students learn. . . by undertaking projects that simulate and simplify practice; or they take on real-world projects under close supervision" (Schön 1987, 37). In the healthcare professions, one of the ways the practicum is reified i...

With the increasing integration between information systems and the work systems they support, methods that focus on computerized aspects of information systems but skim over the work system are increasingly inadequate. To address work system issues, systems analysis and design methods should apply general principles that help in assessing likely positive and negative impacts of conceivable cha...
