Recently, community search over graphs has gained significant interest. In applications such as analysis of protein-protein interaction (PPI) networks, citation graphs, and collaboration networks, nodes tend to have attributes. Unfortunately, most previous community search algorithms ignore attributes and result in communities with poor cohesion w.r.t. their node attributes. In this paper, we s...

Background: Nonmarket stated preferences valuation, especially discrete choice experiments (DCEs), is one of the commonly used techniques in the health sector. The primary purpose of this approach is to help select attributes and attributes-levels that are able to properly describe health care products or services. This study aimed at developing attributes and attributes-levels for basic health...

The face is an important part of the identity of a person. Numerous applications benefit from the recent advances in prediction of face attributes, including biometrics (like age, gender, ethnicity) and accessories (eyeglasses, hat). We study the attributes’ relations to other attributes and to face images and propose prediction models for them. We show that handcrafted features can be as good ...

The statistical notion of variable interaction is relevant to learning diiculty. This is substantiated by an empirical study that examines the relationship between concept variation and predictive accuracy, extended by analizing the variable interaction as a cause of concept variation. One of six learning systems empirically studied, MRP, exhibits a distinctive advantage ascribed to characteris...

Linear hierarchies, the classical pecking-order structures, are formed readily in both nature and the laboratory in a great range of species including humans. However, the probability of getting linear structures by chance alone is quite low. In this paper we investigate the two hypotheses that are proposed most often to explain linear hierarchies: they are predetermined by differences in the a...

Performance at Transportation Security Administration (TSA) airport checkpoints must be consistently high to skillfully mitigate national security threats and incidents. To accomplish this, Transportation Security Officers (TSOs) must exceptionally perform in threat detection, interaction with passengers, and efficiency. It is difficult to measure the human attributes that contribute to high pe...

Sight Quest is a location-based game for mobile camera devices that uses paper maps as game boards and is played in urban spaces. The players have to solve different quests requiring knowledge about geographic objects on the map as well as real and fictional attributes of these objects. The players move their mobile camera device like a magic lens over the map in order to make the attributes of...

The ubiquity of recommender systems has increased the need for higher-bandwidth, natural and efficient communication with users. This is increasingly filled by recommenders that support language interaction, often conversationally. Given inherent semantic subjectivity present in language, we argue modeling subjective attributes a critical, yet understudied, avenue AI research. We propose novel ...

BUILD-IT is a planning tool based on computer vision technology, supporting complex planning and composition tasks. It allows a group of people, seated around a table, to interact with objects in a virtual scene using real bricks. A plan view of the scene is projected onto the table, where object manipulation takes place. Hence, manipulation and display are coincident. A perspective view is pro...

Building on world-systems theory, simulation models of 5-line intersocietal networks were generated in an effort to understand systemic power hierarchies. The societal nodes were exclusively connected by three types of interaction: migration, warfare, and unequal trade. These networks can be considered “mixed relation” networks due to the ways in which these types of ties combine positive and n...
