Dynamic System Adaptation by Constraint Orchestration

For Paradigm models, evolution is just-in-time specified coordination conducted by a special reusable component McPal. Evolution can be treated consistently and on-the-fly through Paradigm's constraint orchestration, also for originally unforeseen evolution. UML-like diagrams visually supplement such migration, as is illustrated for the case of a critical section solution evolving into a pipeline architecture.Comment: 19 page

Formalizing Adaptation On-the-Fly

AbstractParadigm models specify coordination of collaborating components via constraint control. Component McPal allows for later addition of new constraints and new control in view of unforeseen adaptation. After addition McPal starts coordinating migration accordingly, adapting the system towards to-be collaboration. Once done, McPal removes obsolete control and constraints. All coordination remains ongoing while migrating on-the-fly, being deflected without any quiescence. Through translation into process algebra, supporting formal analysis is arranged carefully, showing that as-is and to-be processes are proper abstractions of the migrating process. A canonical critical section problem illustrates the approach

Adaptive management of applications across multiple clouds:the SeaClouds approach

How to deploy and manage, in an efficient and adaptive way, complex applications across multiple heterogeneous cloud platforms is one of the problems that have emerged with the cloud revolution. In this paper we present context, motivations and objectives of the EU research project SeaClouds, which aims at enabling a seamless adaptive multi-cloud management of complex applications by supporting the distribution, monitoring and migration of application modules over multiple heterogeneous cloud platforms. After positioning SeaClouds with respect to related cloud initiatives, we present the SeaClouds architecture and discuss some of its aspect, such as the use of the OASIS standard TOSCA and the compatibility with the OASIS CAMP initiative

Contextual Adaptation. Human Functioning as Dynamic Interaction: A Social Work Perspective

Despite the recent development of theories in the social sciences that define human development and functioning in an integrated, nuanced and complex manner, the social work concept of “person-in-environment” remains outdated and limited. This is in part due to the “person” and “environment”--the biological, psychological, and social environments--being defined in distinction from one another. In order to remain current and effective in arguing on behalf of a clear professional voice in the field, social workers must not only engender but also promote a fundamental practice perspective that addresses complexity. A reformulation of “person-in-environment” can help social workers more fully realize the desire to unite under the common professional mandates requiring that both a “person-in-environment” perspective and a full biopsychosocial picture be taken into clinical accounts. To meet this aim I develop the concept of contextual adaptation, a new definition of “person-in-environment” reliant on tenets of nonlinear dynamic systems theory, specifically chaos theory. Nonlinear dynamic systems theory offers a unique opportunity for social workers to retain the core potentiality and utility of “person-in-environment,” that which enables them to account for the importance of environment, but reformulate it so as to create a more viable concept. Contextual adaptation is defined as a biopsychosocial process allowing for an integrated focus on the influence and management of the overlapping contexts of self, interpersonal experience, and sociocultural demands. Human development and functioning are established as a spectrum of adaptive behavior based on the regulation of the needs and requirements of internal processes, relational experience, and external influence

A few-shot learning method for tobacco abnormality identification

Tobacco is a valuable crop, but its disease identification is rarely involved in existing works. In this work, we use few-shot learning (FSL) to identify abnormalities in tobacco. FSL is a solution for the data deficiency that has been an obstacle to using deep learning. However, weak feature representation caused by limited data is still a challenging issue in FSL. The weak feature representation leads to weak generalization and troubles in cross-domain. In this work, we propose a feature representation enhancement network (FREN) that enhances the feature representation through instance embedding and task adaptation. For instance embedding, global max pooling, and global average pooling are used together for adding more features, and Gaussian-like calibration is used for normalizing the feature distribution. For task adaptation, self-attention is adopted for task contextualization. Given the absence of publicly available data on tobacco, we created a tobacco leaf abnormality dataset (TLA), which includes 16 categories, two settings, and 1,430 images in total. In experiments, we use PlantVillage, which is the benchmark dataset for plant disease identification, to validate the superiority of FREN first. Subsequently, we use the proposed method and TLA to analyze and discuss the abnormality identification of tobacco. For the multi-symptom diseases that always have low accuracy, we propose a solution by dividing the samples into subcategories created by symptom. For the 10 categories of tomato in PlantVillage, the accuracy achieves 66.04% in 5-way, 1-shot tasks. For the two settings of the tobacco leaf abnormality dataset, the accuracies were achieved at 45.5% and 56.5%. By using the multisymptom solution, the best accuracy can be lifted to 60.7% in 16-way, 1-shot tasks and achieved at 81.8% in 16-way, 10-shot tasks. The results show that our method improves the performance greatly by enhancing feature representation, especially for tasks that contain categories with high similarity. The desensitization of data when crossing domains also validates that the FREN has a strong generalization ability

The Funambulist Papers, Volume 1

This book is a collection of thirty-five texts from the first series of guest writers’ essays, written specifically for The Funambulist weblog from June 2011 to November 2012. The idea of complementing Lambert’s own texts on his blog with those written by others originated from the idea that having friends communicate with each other about their work could help develop mutual interests and provide a platform to address an audience. Thirty-nine authors of twenty-three nationalities were given the opportunity to write essays about a part of their work that might fit with the blog’s editorial line. Overall, two ‘families’ of texts emerged, collected in two distinct parts in this volume. The first part, The Power of the Line, explores the legal, geographical and historical politics of various places of the world. The second part, Architectural Narratives, approaches architecture in a mix of things that were once called philosophy, literature and art. This dichotomy represents the blog’s editorial line and can be reconciled by the obsession of approaching architecture without care for the limits of a given discipline. This method, rather than adopting the contemporary architect’s syndrome that consists in talking about everything but being an expert in nothing, attempts to consider architecture as something embedded within (geo)political, cultural, social, historical, biological, and dromological mechanisms that widely exceed what is traditionally understood as the limits of its expertise
