IEEE Workshop on Machine Learning for Signal Processing

作者： George A. Papakostas Konstantinos I. Diamantaras Dept. Computer and Informatics Engineering EMaTTech Kavala Greece Dept. Information Technology TEI of Thessaloniki Sindos Greece

An efficient parallel implementation of the recently proposed Slackmin classification algorithm that minimizes the mean squared slack variables energy is proposed in this paper. The efficacy of the resulted scheme is demonstrated both in terms of accuracy and computation speed. The parallelization of the Slackmin algorithm is achieved in the framework of GPU programming. Based on this framework the “cuLSlackmin” algorithm for linear problems was implemented, by using the CUDA C/C++ programming model and proposed herein. The introduced parallel algorithm is making use of the advantages imposed by the GPU architecture and achieves high classification rates in a short computation time. A set of experiments with some UCI datasets have shown the high performance of the cuLSlackmin algorithm compared to the Slackmin, LIBSVM and GPULIBSVM algorithms. The high performance of cuLSlackmin algorithm makes it appropriate for big data classification problems.

It is known that the OWL 2RL Web Ontology Language Profile has PTime data complexity and can be translated into Datalog. However, the result of translation may consist of a Datalog program and a set of constraints in the form of negative clauses. Therefore, a knowledge base in OWL 2RL may be unsatisfiable. In the current paper we first identify a maximal fragment of OWL 2RL, called OWL 2RL+, with the property that every knowledge base expressed in OWL2RL+ can be translated to a Datalog program and hence is satisfiable. We then propose some extensions of OWL 2RL and OWL 2RL + that still have PTime data complexity. © 2014 Springer-Verlag Berlin Heidelberg.

International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIHMSP)

作者： Takayuki Ishihara Michiharu Niimi Dept. of Computer Science and Informatics Kyushu Institute of Technology Iizuka-shi Fukuoka Japan

The matrix barcodes known as Quick Response (QR) codes, which are enable us to import printed digital information into smart-phone or cell phone through its digital camera easily, are rapidly becoming widespread not only Japan but also Asia, Europe and America. However, an attacker is easily able to lead malicious web-sites by putting a unauthenticated QR code on a authenticated QR code. We propose a compatible 2d-code having tamper detection system with QR-code. In digital signature system, a hash value of a message is calculated firstly, and then the hash value is encrypted by a secret key which is a pair of public key cryptography system. Then, a sender sends the message and the encrypted hash value to a receiver. In the receiver side, the hash value of a sent message is calculated and the hash value with encrypted is decrypted using a public key which is a pair of public key cryptography system. The receiver can detect modification of the message by comparing the two hash values. The encrypted hash value is embedded by using Wet Paper code within cells of QR-codes. In this paper, we report the robustness of reading cells of QR code which plays an important role in our code and the state of the progress for the implementation of the proposed system.

Recent work has proposed an enhancement of Formal Concept Analysis (FCA) in a tunable, hybrid formal context including both numerical and nominal data [1]. This work introduces FCknn, that is a granular knn classifier based on hybrid concepts, whose effectiveness is demonstrated on benchmark datasets from the literature including both numerical and nominal data. Preliminary experimental results compare well with the results by alternative classifiers from the literature. Formal concepts are interpreted as descriptive decision-making knowledge (rules) induced from the data.

International Wireless Communications and Mobile Computing Conference, IWCMC

作者： C. Bouras V. Kapoulas K. Stamos N. Stathopoulos N. Tavoularis Computer Engineering and Informatics Dept. University of Patras Greece Computer Technology Institute and Press “Diophantus” Patras Greece

The main focus of this work is the effort to minimize the power consumption on mobile devices such as notebooks, netbooks, tablets, tablets, smartphones, etc. by adjusting the transmission power of the wireless card, thus extending the battery life. In order to achieve that, we provide a mechanism (which we call Signal Adaptation Mechanism - SAM) that optimizes the power depending on the quality of the connection. This mechanism measures the quality of the transmission and adjusts the transmission power accordingly, by utilizing an expanded array of metrics along the Received Signal Strength Indicator (RSSI), for more accurate estimation. It also aims at easy implementation on various wireless adapters. In order to evaluate, fine-tune and improve the mechanism, a list of experiments has been performed. These experiments were conducted on a real (as opposed to simulated) ad-hoc network, where the nodes of the networks followed varying moving patterns.

Although statistical graph comprehension has been investigated in cognitive psychology, it has not been reported in cognitive neuroscience. The study designed an experimental condition, i.e., a statistical graph (SG), and two control conditions, i.e., a text (ST) and a statistical graph with text (SGT), where the ST is a verbal description of the information from the SG, and the SGT is a mixed graph + textual description. We used fMRI to analyze the brain activity of 36 normal subjects while they passively view the statistical information presented in any of SG, ST, and SGT. The results indicate that statistical graph comprehension requires the involvement of both ventral and dorsal streams, with more dependence on the ventral stream than the dorsal. © 2014 Springer International Publishing.

Wireless sensor networks enable cost-effective data collection for tasks such as precision agriculture and environment monitoring. However, the resource-constrained nature of sensor nodes, which often have both limited computational capabilities and battery lifetimes, means that applications that use them must make judicious use of these resources. Research that seeks to support data intensive sensor applications has explored a range of approaches and developed many different techniques, including bespoke algorithms for specific analyses and generic sensor network query processors. However, all such proposals sit within a multi-dimensional design space, where it can be difficult to understand the implications of specific decisions and to identify optimal solutions. This paper presents a benchmark that seeks to support the systematic analysis and comparison of different techniques and platforms, enabling both development and user communities to make well informed choices. The contributions of the paper include: (i) the identification of key variables and performance metrics;(ii) the specification of experiments that explore how different types of task perform under different metrics for the controlled variables;and (iii) an application of the benchmark to investigate the behavior of several representative platforms and techniques. © Copyright 2014 ACM 978-1-4503-2722-0/14/06$15.00.

As computing becomes ubiquitous, researchers and engineers aim to exploit the potential of the pervasive systems in order to introduce new types of services and address inveterate and emerging problems. This process will, eventually, lead us to the era of urban computing and the Internet of Things; the ultimate goal being to improve our quality of life. But these concepts typically require direct and constant interaction of computing systems with the physical world in order to be realized, which inevitably leads to the introduction of a range of safety and privacy issues that must be addressed. One such important aspect is the fine-grained control of access to the resources of these pervasive embedded systems, in a secure and scalable manner. This paper presents an implementation of such a secure policy-based access control scheme, focusing on the use of well-established, standardized technologies and considering the potential resource-constraints of the target heterogeneous embedded devices. The proposed framework adopts a DPWS-compliant approach for smart devices and introduces XACML-based access control mechanisms. The proof-of-concept implementation is presented in detail, along with a performance evaluation on typical embedded platforms.

Fault localization in all-optical ring networks

Fault localization in all-optical ring networks

European Conference on Networks and Optical Communications (NOC)

作者： Mohammed L. Ali Pin-Han Ho János Tapolcai Dept. of Electrical and Computer Engineering University of Waterloo Canada Dept. of Telecommunications and Media Informatics Budapest University of Technology and Economics Hungary

The paper investigates dual-link fault localization in all-optical ring networks using optical probes (called monitoring bursts). By defining a single monitoring node (MN) in the ring that initiates and terminates a set of monitoring trails (m-trails), the MN can localize any dual-link fault by inspecting the on-off status of the launched optical bursts. We investigate relevant problems in the proposed fault monitoring approach, including m-trail allocation, burst launching time scheduling, and node switch fabric configuration, where constructions are developed to derive optimal solutions and are further examined in numerical experiments. 2(|Ej| - 1) m-trails and at most (2δ + L)(|E| - 1) + δ(|E| - 2) of monitoring delay are required for dual-link fault localization from a single MN in a ring with|E| links, where δ is the burst propagation delay along a unidirectional link and L is the burst length.
