The sparsity problem in collaborative filtering (CF) is a major bottleneck for most CF methods. In this paper, we consider a novel approach for alleviating the sparsity problem in CF by transferring useritem rating patterns from a dense auxiliary rating matrix in other domains (e.g., a popular movie rating website) to a sparse rating matrix in a target domain (e.g., a new book rating website). ...

BACKGROUND Urban and rural populations have different rates of psychotic illness. If psychosis exists as a continuous phenotype in nature, urban-rural population differences in the rate of psychotic disorder should be accompanied by similar differences in the rate of abnormal mental states characterized by psychotic or psychosislike symptoms. METHODS A random sample of 7076 individuals aged 1...

Since the early days of arti5cial intelligence, there has been interest in having a computer teach itself how to play a game of skill, like checkers, at a level that is competitive with human experts. To be truly noteworthy, such e7orts should minimize the amount of human intervention in the learning process. Recently, co-evolution has been used to evolve a neural network (called Anaconda) that...

BACKGROUND Abattoir condemnations may play an important role in a food animal syndromic surveillance system. Portion condemnation data may be particularly useful, as these data can provide more specific information on health outcomes than whole carcass condemnation data. Various seasonal, secular, disease, and non-disease factors have been previously identified to be associated with whole carca...

A novel approach to high level synthesis of AsIcs based on a data driven execution model is presented. The synthesis procedure is directed at prodncing highly parallel Aslcs providing high throughput through pipelining. The major benefits of our approach are its potential for higher speed, ease of design, ease of verification and testing.

Objective: To review the evidence regarding the usefulness of patient demographic characteristics, driving history, and cognitive testing in predicting driving capability among patients with dementia and to determine the efficacy of driving risk reduction strategies. Methods: Systematic review of the literature using the American Academy of Neurology’s evidence-based methods. Recommendations: F...

1 Abstract This paper describes a control system for industrial applications with a custom protocol and communication system. The project has been partially supported by the Spanish initiative for the microelectronics promotion (GAME initiative) and also by a private company. Two ASICs have been developed using synthesis, high-level design and macrocell integration techniques. Finally the syste...
