Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

No full textThe availability of efficient software implementations of neural network algorithms is a key task in the development phase to evaluate the network results in real cases. In this letter we address the problem of optimizing the sequential algorithm for the Boltzmann Machine (BM). We present a solution which is based on the locality properties of the algorithm and enables a very efficient computation of the cost difference between two configurations. Since the algorithm performance depends on the number of accepted state transitions in the annealing process, we formulate a theoretical procedure to estimate the acceptance probability of a state transition. In addition, we provide experimental data on a well-known optimization problem (TSP) to have a numerical verification of the theory, and to show that the proposed solution obtains a speedup between 3 and 4 in comparison with the traditional algorithm
Clustered Boltzmann machines: Massively parallel architectures for constrained optimization problems
No full textDESIGN OF A MASSIVELY PARALLEL SIMD ARCHITECTURE FOR THE BOLTZMANN MACHINE
No full textThe Boltzmann Machine represent an interesting computation paradigm that can be applied in several fields such combinatorial optimization, pattern recognition and knowledge representation. Although Boltzmann Machine has been proved to give high quality results, its application in real problems has been limited by the heavy computational load it requires mainly due to the sequential nature of the simulated annealing algorithm needed for equilibrating the network. Thank to a parallel algorithm, we have developed, Boltzmann Machine features can now be exploited by using a parallel machine. We describe the design of a first prototype of a parallel SIMD architecture that supports the Boltzmann Machine and allows a speedup of N where N is the number of the processing nodes
Variations on the Author
Get PDF“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
