Reasoning about Multiple Plans in Dynamic Multi-agent Domains (Extended Abstract)
No full text) Jonathan Gratch University of Southern California, Information Sciences Institute 4676 Admiralty Way, Marina del Rey, CA, 90292 [email protected] Introduction Classical planning algorithms such as TWEAK (Chapman, 1987) or SNLP (McAllester and Rosenblitt 1991) were developed to solve relatively simple problems in static, single-agent environments. Remarkably, recent applications have demonstrated that this basic technique, with modest extensions, can plan for large-scale, dynamic, multi-agent environments such as intelligent tutoring (Rickel and Johnson, 1997) and military planning (Wilkins and Myers, 1996; Hill et al., 1997). These planning "agents" go beyond the traditional focus on plan generation. These systems persist over extended time periods and demand a more dynamic approach to planning: goals change over time, plan generation must be interleaved with plan execution and plan repair. Systems that interact with other agents must distinguish between my activities, your activitie..
Supporting meetings in Virtual Worlds with enhanced Communication features
No full textWith the rapid growth in the use of computer for addressing our day to day needs and the increased use of technology in our daily life, we cannot imagine a day without the use of the internet for our routine needs. Today, without any doubt in our mind we can say that technology has taken over human lives completely. A new era of computing has evolved where computers and the internet have a huge impact on everyone‟s life. A lot of research has been done and is in process for generated tools and devices which will bring the world even closer. It started with telephone in the last century and since then till today there have been huge number of tools and devices that try to give the users who are geographically far away a sense of co-presence. The latest technology making rounds is the Virtual World technology. The popularity and impact of online virtual worlds is worth making a note of. It needs to be seen now, how does it really betters people lives. One such persistent virtual world is Second Life. The number of users and organizations associated with this world is impressive. It provides users with the right amount of collaborative content with a set of communication features. Second Life provides its users with unique meeting support which gives them a sense of co-presence achieved nowhere else. This thesis focuses upon the kind of meeting support, collaborative content and the communication features provided by the virtual world that will allow its users to avoid the need for travel and long distance meetings can be achieved successfully in such an environment. This will help the travel time to be converted to productive office time as well as the costs involved in such meetings can also be reduced drastically. Such kind of meetings will also prove eco-friendly as they will save on fuel consumption and benefit from reduced pollution
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Autonomous closed-loop biofeedback : an introduction and a melodious application
No full textThis chapter is from the forthcoming The Oxford Handbook of Affective Computing edited by Rafael Calvo, Sidney K. D'Mello, Jonathan Gratch, and Arvid Kappas. This chapter defines the core concepts surrounding biofeedback and denotes their relations. Subsequently, a closed-loop human-machine architecture is introduced in which a biofeedback protocol is executed. This architecture is brought from theory to practice via a personalized affective music player (AMP). Regression and kernel density estimation are applied to model the physiological changes elicited by music. The AMP was validated via a real-world evaluation over the course of several weeks. Results show that our autonomous closed-loop biofeedback system can cope with noisy situations and handle large interindividual differences in the music domain. The AMP augments music listening, where its techniques enable autonomous affect guidance. Our approach provides valuable insights for affective computing and autonomous closed-loop biofeedback systems in general.
