simd computers and collection-oriented languages, like C , are designed to perform the same computation on each data item or on just a subset of the data. Subsets of processors or data items are implemented via an activity bit and a stack of activity bits when subsets of subsets are supported. We present an implementation of activity stacks based on counters. At a given stack depth n, the numbe...

The DARE architecture is an emotion-based agent model. This model is based on a double-representation of stimuli: a complex representation, oriented towards recognition, and simple one, oriented towards feature extraction. These two representations are associated and stored in the agent memory. This paper describes a formalization of an indexing mechanism. Given a new stimulus, the goal of this...

validation is an important enterprise especially when a test is a high stakes one. demographic variables like gender and field of study can affect test results and interpretations. differential item functioning (dif) is a way to make sure that a test does not favor one group of test takers over the others. this study investigated dif in terms of gender in the reading comprehension subtest (35 i...

Previous evidence has suggested a functional-anatomic dissociation between conscious and nonconscious processing during retrieval where early visual regions BA17/18 are associated with nonconscious processing and late visual regions BA19/37 are associated with conscious processing. However, evidence for this dissociation has only been observed using a limited number of experimental paradigms. I...

Collaborative filtering aims to make use of users’ feedbacks to improve the recommendation performance, which has been deployed in various industry recommender systems. Some recent works have switched from exploiting explicit feedbacks of numerical ratings to implicit feedbacks like browsing and shopping records, since such data are more abundant and easier to collect. One fundamental challenge...

Utility-oriented mining which integrates utility theory and data is a useful tool for understanding economic consumer behavior. Traditional algorithms high-utility patterns (HUPs) applies single/uniform minimum threshold (minutil) to obtain the set of HUPs, but in some real-life circumstances, specific products may bring lower utilities compared with others, their profit offer vital information...

equating test scores is an important issue in large scale testing. almost all standardized tests have several forms which vary in difficulty. new forms are written and added every year. when the items in different forms of a test vary in difficulty, direct comparison of test-takers who have taken different forms and are at the same ability level is not possible; hence, the issue of test fairnes...
