—In computer vision, image datasets used for classification are naturally associated with multiple lab.ls and comprised of multiple views, because each image may contain several objects (e.g. pedestrian, bicycle and tree) and is properly characterized by multiple visual features (e.g. color, texture and shape). Currently availab.e tools ignore either the lab.l relationship or the view complementary. Motivated by the success of the vector-valued function that constructs matrix-valued kernels to explore the multi-lab.l structure in the output space, we introduce multi-view vector-valued manifold regularization (MV3MR) to integrate multiple features. MV3MR exploits the complementary property of different features and discovers the intrinsic local geometry of the compact support shared by different features under the theme of manifold regularization. We conducted extensive experiments on two challenging, but popular datasets, PASCAL VOC’ 07 (VOC) and MIR Flickr (MIR), and validated the effectiveness of the proposed MV3MR for image classification.

Research questions in biodiversity are as diverse and heterogeneous as data are. Most metadata standards are mainly data-focused and pay little attention to the search perspective. In this work, we introduce a method to analyze the actual information need of biodiversity scholars based on two individual studies: (1) a series of workshops with domain experts and (2) an analysis of research and search questions collected in three different biodiversity projects. We finally present 12 high-level entities that appear in all kinds of biological data across the different sources evaluated.

Cloud robotics is a field of robotics which enables robots to benefit from the powerful computational, storage, and communication resources provided by the Cloud. This allows for smart and low-cost robots having brain in the Cloud. However, network latency and too much reliance on the Cloud could lead to a brainless robot. The need for a mediator is thus evident to coordinate the communication. In this paper, we propose a multi-process mediator framework for Cloud robotics, named CRC2. The proposed framework makes use of the smartphone resources and offers a service-based approach to establish and manage a collab.rative communication channel between robot and the Cloud. The proposed framework is lightweight and is focused to minimize communication latency. In addition, it automates robotic tasks execution and provides smartphone resources integration.

In this paper, Traveling Salesman Problem with Hotel Selection (TSPHS), an extension of the Traveling Salesman Problem (TSP) has been considered. A mathematical formulation has been presented in the framework of Mixed Integer Linear Programming (MILP). Subsequently, the problem has been formulated in the novel framework of tropical mathematics and a strategy to obtain exact solution has been proposed. The performance of the proposed solution, in terms of the optimality and computational time requirement, has been compared with the solution strategies availab.e in literature including traditional MILP. The results indicate that the proposed solution strategy not only leads to optimal results but also is computationally much more efficient.

Service-oriented computing has long outgrown the enterprise. Today, personal livingenvironments feature an increasing number of convenience-, health-and securityrelatedapplications provided by distributed interacting devices and services (oftencalled smart homes), which do not only support users but require management taskssuch as application installation, configuration and continuous maintenance. Thesetasks are becoming complex and error-prone. One way to escape this situation is toenable service platforms to configure and manage themselves. The approach presentedhere extends services with semantic descriptions to enable platform-independent autonomousservice level management and mediation using model driven architectureand autonomic computing concepts. It has been implemented as a semantic autonomicmanager, whose concept, prototypical implementation and evaluation are presented.

Non-intrusive load monitoring (NILM) is a popular approach to estimate appliance-level electricity consumption from aggregate consumption data of households. Assessing the suitability of NILM algorithms to be used in real scenarios is however still cumbersome, mainly because there exists no standardized evaluation procedure for NILM algorithms and the availab.lity of comprehensive electricity consumption data sets on which to run such a procedure is still limited. This paper contributes to the solution of this problem by: (1) outlining the key dimensions of the design space of NILM algorithms;(2) presenting a novel, comprehensive data set to evaluate the performance of NILM algorithms;(3) describing the design and implementation of a framework that significantly eases the evaluation of NILM algorithms using different data sets and parameter configurations;(4) demonstrating the use of the presented framework and data set through an extensive performance evaluation of four selected NILM algorithms. Both the presented data set and the evaluation framework are made publicly availab.e.

We are at the dawn of a huge data explosion therefore companies have fast growing amounts of data to process. For this purpose Google developed MapReduce, a parallel programming paradigm which is slowly becoming the de facto tool for Big Data analytics. Although to some extent its use is already wide-spread in the industry, ensuring performance constraints for such a complex system poses great challenges and its management requires a high level of expertise. This paper answers these challenges by providing the first autonomous controller that ensures service time constraints of a concurrent MapReduce workload. We develop the first dynamic model of a MapReduce cluster. Furthermore, PI feedback control is developed and implemented to ensure service time constraints. A feedforward controller is added to improve control response in the presence of disturbances, namely changes in the number of clients. The approach is validated online on a real 40 node MapReduce cluster, running a data intensive Business Intelligence workload. Our experiments demonstrate that the designed control is successful in assuring service time constraints. © IFAC.

The complexity of today's Internet environment means new law enforcement requirements are likely to introduce unanticipated security flaws. Political and law enforcement leaders in the U.S. and the U.K. have called for Internet systems to be redesigned to ensure government access to information even encrypted information. There are three general problems. First, providing exceptional access to communications would force a U-turn from the best practices now being deployed to make the Internet more secure. These practices include forward secrecy, where decryption keys are deleted immediately after use, so that stealing the encryption key used by a communications server would not compromise earlier or later communications. Second, building in exceptional access would substantially increase system complexity. Third, exceptional access would create concentrated targets that could attract bad actors. Moreover, law enforcement's stated need for rapid access to data would make it impractical to store keys offline or split keys among multiple key holders, as security engineers would normally do with extremely high-value credentials.

Ensuring the aspired outcome quality of network-based applications has ever implied an appropriate prognosis of the performance behavior the underlying communication structures will exhibit prior to potential optimization steps. However, the reliable forecast of correlative metrics is still a challenging task, especially in terms of wireless network systems that reject centralized or manual administration. In the context of our prospective self-management concept for autonomous analysis and control of volatile performance characteristics in Wireless Sensor networks (WSNs), we relate a common network property known as packet transfer delay to various adjustable parameters peculiar to such radio network technologies. Our hands-on experiments reveal the reproducible influence of packet size, backoff period, and number of active neighbor nodes on the medium access procedure and involved performance indicators. By means of a closed formulation of permutable weighted drivers, we investigate the average-case predictability of inter-node end-to-end delays for arbitrary configurations of given network parameters. We validate our prediction method against basic multi-hop networking scenarios while verifying its practicability on a typical resource-scarce WSN platform. Leveraging measurement-driven inspection and conditional modeling of network attributes based on regression analysis, yield field test results substantiate the high precision of our approach to the estimation of performance-related WSN properties as the basis for application-aware performance optimization subject to projected complements. © 2013 ACM.
