Distributed Asymptotic Minimization of Sequences of Convex Functions by a Broadcast Adaptive Subgradient Method
No full textWe propose a non-hierarchical decentralized algorithm for the asymptotic minimization of possibly time-varying convex functions. In our method, each agent in a network has a private, local (possibly time-varying) cost function, and the objective is to minimize asymptotically the sum of these local functions in every agent (this problem appears in many different applications such as, among others, motion planning, acoustic source localization, and environmental modeling). The algorithm consists of two main steps. First, to improve the estimate of a minimizer, agents apply a particular version of the adaptive projected subgradient method to their local functions. Then the agents exchange and mix their estimates using a communication model based on recent results of consensus algorithms. We show formally the convergence of the resulting scheme, which reproduces as particular cases many existing methods such as gossip consensus algorithms and recent decentralized adaptive subgradient methods (which themselves include as particular cases many distributed adaptive filtering algorithms). To illustrate two possible applications, we consider the problems of acoustic source localization and environmental modeling via network gossiping with mobile agents

Adaptive Projected Subgradient Method and Its Applications to Signal Processing Problems (Plenary Talk by Isao Yamada)
No full textAdaptation and learning over complex networks
No full textThe topic of this special issue of IEEE Signal Processing Magazine is timely and deals with a subject matter that has been receiving immense attention from various research communities, and not only within the signal processing community. Extensive research efforts on information processing over graphs exist within other fields such as statistics, computer science, optimization, control, economics, machine learning, biological sciences, and social sciences. Different fields tend to emphasize different aspects and challenges; nevertheless, opportunities for mutual cooperation are abundantly clear, and the role that signal processing plays in this domain is of fundamental importance. This is because, in all these fields, there is growing interest in performing inference and learning over graphs, such as deducing relationships from interconnections over social networks, modeling interactions among agents in biological networks, performing resource allocation distributively, passing information over networks, optimizing utility functions over graphs, adapting and learning over graphs, etc. Commonalities and significant signal processing run across all these applications. The articles in this special issue help highlight this interplay among disciplines and the significant role that signal processing plays in this domain
Introduction to the issue on adaptation and learning over complex networks
No full textThe topic of this special issue is timely and deals with a subject matter that has been receiving immense attention from various research communities, and not only within the signal processing community. Extensive research efforts on
information processing over graphs exist within other fields such as statistics, computer science, optimization, control,
economics, machine learning, biological sciences, and social sciences. Different fields tend to emphasize different aspects and challenges; nevertheless, opportunities for mutual cooperation are abundantly clear and the role that signal processing plays in this domain is of fundamental importance.

The articles in this special issue report on up-to-date advances in the broad area of information processing over graphs
Reading Yamada Eimi
No full textThe Japanese novelist Yamada Eimi has published many controversial and
popular books. As she herself lives openly and controversially in the same way
that she writes, Yamada Eimi the person is often confused with the narrators of
her stories. This essay is not only a reading of her texts, but also an analysis of
how "Yamada Eimi," the author, is embedded into these texts and then consumed
by the reader.
Starting first with two examples of diametrically opposed readings by the
North American critics Richard Okada and Kuwahara Yasue, I then outline my
reading which falls somewhere in between Okada's and Kuwahara's. Several
Japanese readings of Yamada's writings indicate that Yamada creates her own
world with its own value system and then draws the readers into this system. In
Chapter One, a close reading of three of Yamada's works shows that this system is
an aesthetic code that defines the behaviour, dress and attitude of the female
characters in the stories. Chapter Two then shows how this code is communicated
to the readers. The homosocial "sister" relationships that allow this
communication are also part of how the readers are drawn in. In Chapter Thriee I
combine the aesthetic code with the "sister structure" to illustrate how the reader
is also included in a sister relationship with Yamada Eimi.. Back full circle, I then
show how different readings of the same texts become possible.Arts, Faculty ofAsian Studies, Department ofGraduat
