Style-specific training of a stroke-based recognizer (Extended Abstract)

Two components of the on-line word recognition system developed at the NICI [2, 1] were specialized on each of the three styles: the Kohonen stroke network representing strokes, and the transition network representing occurrences of sequences of strokes. The top-word recognition performance of these specialized agents was compared to that of a recognizer trained on all data (a lumped recognizer). The results reported in this paper show that for agents with a specialized transition network, similar recognition performances are achieved as with the lumped recognizer. For agents with both networks tuned, significant improvements..
Artificial Intelligence
No full textThis report introduces a general formulation of relational behaviours for cooperative real robots and an example of its implementation using the pass between soccer robots of the Middle-Sized League of RoboCup. The framework supports explicit teamwork between two team mates. This implies that both participants know from each other that they are committed to the relational behaviour and that they will not quit without informing the other team members first. The formulation is based on the Joint-Commitment Theory by Cohen and Levesque [2]. The implementation of the pass concerns furthermore the development of two primitive behaviours, the intercept and aimAndPass behaviour, and the introduction of heuristics to support coordinated execution. This implementation is supported by past work on soccer robots navigation. Results of experiments with real robots under controlled situations (i.e., not during a game) are presented to illustrate the described concepts. The framework provides an easy way for implementing relational behaviours and takes care of synchronized execution. Acknowledgement A short word of thanks for those who have been helping me during this graduation research. The main part of this project has been done at the Institute for Systems and Robotics, of the Instituto Superior Técnico in Lisbon Portugal. I would like to thank my supervisor overthere, prof. dr. Pedro Lima, for all his advice and efforts. It is too much to mention all members of the SocRob-group personally, so I thank you all in general for the cooperation in both professional and friendly way. Then, from the Department of Artificial Intelligence of the University of Groningen, I got good advice and guidance from prof. dr. Lambert Schomaker, my internal supervisor. I also want to thank dr. Rineke Verbrugge for revising this report. And I should mention the other students in room 155 and the ping-pong table overthere. Of course I have family and friends who are absolutely valuable at all moments
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
