Implementation of Wyner-Ziv coding based on successive quantization
No full textWyner-Ziv 編碼為一失真壓縮技術，其利用解碼器所能得到的附加資訊(side information)來幫助解碼。我們提出一個能實現的編碼設計方法。同時我們也根據連續式量化架構提出一個量化演算法以用來實現二次高斯(QuadraticGaussian) Wyner-Ziv 編碼。我們使用的編碼架構會使用兩組獨立的成分編碼器(component code)。而利用隨機編碼(random coding)分析，這個編碼架構已經被證明可以達到Wyner-Ziv 邊界(Wyner-Ziv bound)。
我們會利用能夠趨近通道容量(capacity)的通道編碼(channel code)以及能夠趨近資料率失真邊界的訊號源編碼(source code)來實現我們提出的編碼設計方式。和現存的箱式(binning)編碼設計比起來，我們提出的編碼設計方法以及量化演算法有著合理的複雜度以及良好的表現。Wyner-Ziv coding is a lossy compression technique which uses the decoder side information to help reconstruction. We propose a practical code design methodology and a quantization algorithm inspired by successive quantization
to solve the Wyner-Ziv problem in quadratic Gaussian case. Our coding structure uses two independent component codes and this coding structure has been proven to achieve the Wyner-Ziv bound by the random coding analysis.
We also implement it with existing rate-distortion-bound-achieving quantizer and capacity-achieving channel code. Compared to the existing binningbased design approaches, our design methodology and quantization algorithm have reasonable complexity with good performance

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
