From sensors to structures: unsupervised language learning
Authors: James T. Oates
Venue:  (2008)

Children are facile at acquiring the structure and meaning of their native tongues. The ease with which they become language experts belies the complexity of the underlying task &ndash; learning from a raging sea of information. Computational approaches to learning aspects of language typically reduce the problem to learning syntax alone, learning a lexicon alone, or learning semantics alone. These simplifications have led to disconnected solutions and some unreasonable assumptions about inputs to their algorithms. This dissertation addresses the language learning problem for an embodied robot embedded in a rich environment. We present a pair of theoretical contributions and realize them through a suite of algorithmic contributions. Our first theory posits that language learning systems that rely exclusively on syntax can exploit semantics to improve their success. Similarly, systems that learn semantics can exploit syntax to improve their success. We demonstrate this approach through a life-long learning system, and prove a series of theoretical results identifying a class of learnable context-free languages.When learning syntax, most algorithms expect complete knowledge about the language&rsquo;s alphabet (or lexicon). When learning a lexicon, most algorithms never consider the usage of the lexical items when acquiring the lexicon. We relax this assumption and utilize this new information, respectively, in our second theoretical contribution: bootstrapping learning tasks. We introduce a bootstrapped approach to learning a lexicon and a grammar for a class of regular languages. Using phonetic transcriptions of natural language, we report on experimental results for this bootstrap. We also extend our approach to learning both syntax and semantics through bootstrapping the two, using limited knowledge about semantics to infer additional knowledge about syntax, and limited knowledge about syntax to infer additional knowledge about semantics. Finally, the ultimate goal of this research is to ground all learning in real-valued sensor data. We present a set of algorithms that point toward new approaches to incorporating real-valued data into our bootstrap learning systems.

Box invariance in biologically-inspired dynamical systems
Authors: Alessandro Abate, Ashish Tiwari, Shankar Sastry
Venue: Automatica (Journal of IFAC) (2009)

A dynamical system is box invariant if there exists a box-shaped positively invariant region. We show that box invariance can be checked in cubic time for linear and affine systems, and that it remains decidable for classes of nonlinear systems of interest (with polynomial structure). We present results on the robustness of box invariance for linear systems using spectral properties of Metzler matrices. We also present sufficient conditions for establishing box invariance of switched and hybrid systems. In general, we argue that box invariance is a characteristic of many biologically-inspired dynamical models.
First experiences with a classroom recording system
Authors: Paul E. Dickson, W. Richards Adrion, Allen R. Hanson, David T. Arbour
Venue: Proceedings of the 14th annual ACM SIGCSE conference on Innovation and technology in computer science education (2009)

This paper describes our experiences with the first partial deployment of Presentations Automatically Organized from Lectures (PAOL), a lecture recording system developed and tested at the University of Massachusetts Amherst. PAOL automatically records all information presented during lectures using any combination of computer, whiteboard, and overhead presentation and compiles the captured lectures into indexed presentations. We discuss lessons learned from this deployment that have application in lecture recording specifically and classroom technology in general. We also discuss our initial evaluation of created presentations as determined by a small focus group study.
XPL the eXtensible presentation language
Authors: A. Santangelo, A. Gentile, G. Vella, N. Ingraffia, M. Liotta
Venue: Mobile Information Systems (2009)

The last decade has witnessed a growing interest in the development of web interfaces enabling both multiple ways to access contents and, at the same time, fruition by multiple modalities of interaction (point-and-click, contents reading, voice commands, gestures, etc.). In this paper we describe a framework aimed at streamlining the design process of multi-channel, multimodal interfaces enabling full reuse of software components. This framework is called the eXtensible Presentation architecture and Language (XPL), a presentation language based on design pattern paradigm that keeps separated the presentation layer from the underlying programming logic. The language supplies a methodology to expedite multimodal interface development and to reduce the effort to implement interfaces for multiple access devices, by means of using the same code. This paper describes a methodology approach based on Visual Design Pattern (ViDP) and Verbal Design Pattern (VeDP), offering examples of multimodal and multichannel interfaces created with the XPL Editor.
A new evidential trust model for open communities
Authors: Jin Wang, Huai-Jiang Sun
Venue: Computer Standards Interfaces (2009)

Open communities allow anonymous members to join and leave anytime, in which interactions commonly take place between parties who have insufficient information about each other. The openness brings risk to both the service provider and consumer. Trust is an important tool in human life, as it enables people to get along with strangers. It is accepted that trust management is a potential way to solve the above problem in computational systems. A trust management mechanism can assist members in the open community to evaluate each other and decide which and whether to interact. It provides an incentive to a good behavior and gives a punishment to a malicious behavior. The representation of trust in current computational trust and reputation models can be classified into four categories. We present a new evidential trust model based on the Dezert-Smarandache theory, which has a higher expressiveness than the trust models based on the Dempster-Shafer theory of evidence. We propose a smooth and effective approach of trust acquisition. The general rule of combination of the Dezert-Smarandache theory is used for trust aggregation. We consider that trust is transitive and present a rule of trust transitivity for our model. Lastly, we evaluate our model experimentally.
An overview of privacy improvements to k-optimal DCOP algorithms
Authors: Rachel Greenstadt
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 2 (2009)

For agents to be trusted with sensitive data, they must have mechanisms to protect their users' privacy. This paper explores the privacy properties of k-optimal algorithms: those algorithms that produce locally optimal solutions that cannot be improved by changing the assignments of k or fewer agents. While these algorithms are subject to large amounts of privacy loss, they can be modified to reduce this privacy loss by an order of magnitude. The greatest improvements are achieved by replacing the centralized local search with a distributed algorithm, such as DPOP.
An SVD analysis of equispaced polynomial interpolation
Authors: John P. Boyd, Alan M. Sousa
Venue: Applied Numerical Mathematics (2009)

Runge showed more than a century ago that polynomial interpolation of degree N on a uniform, evenly-spaced grid may diverge as N->~. Here, we present a new angle on polynomial interpolation and the Runge Phenomenon by performing an SVD analysis of the interpolation matrix. We prove that the observed exponential-with-N error growth of the Runge Phenomenon requires that at least the smallest singular value of the interpolation matrix must decay to zero exponentially fast with N, and the matrix condition number @k must grow exponentially with N. Experimentally, four-fifths of the singular values are O(1); the remaining one-fifth of singular values decay exponentially fast with increasing mode number j. The corresponding U modes of the SVD factorization are well approximated by Hermite functions. SVD filtering, which is a common strategy for coping with ill-conditioned matrices by omitting modes of tiny singular value, gave errors no smaller than 7% for Runge's exemplary f(x). Any similar anti-Runge strategy that is based on treating the ''good'' modes (of O(1) singular values) differently from the ''bad'' modes of small singular value is likely to fail because these two groups of modes are strongly coupled. A better strategy for exploiting the SVD factorization remains elusive.
Proposal and analysis of biologically-inspired symbiotic P2P file-sharing networks
Authors: Tohru Morimoto, Naoki Wakamiya, Masayuki Murata
Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

Recently, various overlay networks have been widely deployed over physical IP networks. Since selfish behavior of overlay networks to satisfy demands of their applications and users often conflicts with each other, performance of the overall network system and quality of service offered to users easily deteriorate. To tackle the problem, our research group proposes the framework called overlay network symbiosis based on the biological symbiosis model where different bacteria coexist in the shared medium. In the overlay network symbiosis, overlay networks directly and/or indirectly interact with each other through the shared environment and accomplish cooperative or collaborative control. In this paper, as an example of biologically-inspired symbiotic overlay networks, we propose a mechanism that enables different P2P file-sharing networks to cooperate and live together with mediation of a portal server. In our proposed mechanism, the portal server provides users with transparent utilization of multiple P2P file-sharing networks by handling search requests and shared files in place of users. Through numerical analysis, we showed that the proposed mechanism improved the hit ratio of search requests in comparison to the scenario where P2P file-sharing networks were independent.

Optimization of tag reading performance in generation-2 RFID protocol
Authors: Chonggang Wang, Mahmoud Daneshmand, Kazem Sohraby
Venue: Computer Communications (2009)

Radio frequency identification (RFID) provides a non-line-of-sight (NLOS) and contactless approach for object identification. But if there are multiple tags in the range of an RFID reader, tag collision can take place due to radio signal interference and therefore an anti-collision algorithm is required to resolve collisions. Recently, EPCglobal RFID generation-2 (Gen-2) protocol [EPCglobal Specification, EPCTM radio-frequency identity protocols class-1 generation-2 UHF RFID protocol for communications at 860MHz-960MHz, version 1.0.9, January 2005. Available from: ] is proposed for ultra-high frequency (UHF) passive tags and is being deployed. Gen-2 designs a slotted random anti-collision algorithm, especially, an adaptive slot-counter (Q) selection algorithm. The integer-valued parameter Q in Gen-2 plays a critical role in tag collision resolution. This adaptive algorithm dynamically adjusts the value of Q based on the type of replies from tags. In this paper, we propose an optimal Q algorithm that determines the optimal values of Q according to the number of remaining tags and in turn to optimize tag identification speed (TIS) and query success rate (QSR), respectively. It's been demonstrated through extensive simulations that the proposed algorithm achieves higher TIS than Gen-2 adaptive Q algorithm.

Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part II (2009)

A feature extraction method of palmprint recognition based on Two-Dimensional Principal Component Analysis (2DPCA) is proposed in this work. A series of experiments were performed on the PolyU- Online- Palmprint ---Database with a nearest neighbor classifier and cosine distance. The recognition rate is 99.14%. The 2DPCA method has more recognition accuracy and more computationally efficient than PCA, especially in the small training samples. At the same time the selection of threshold has been researched in different application systems.
Control the Complex Networks with Different Dynamical Nodes by Impulse
Authors: Qunjiao Zhang, Junan Lu
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part II (2009)

This paper investigates the problem of stability in complex dynamical networks. Based on the stability theory for impulsive differential equations, an impulsive control scheme is proposed to achieve impulsive stability for complex dynamical networks with different dynamical nodes. The control strategy are generalized for the network models with diffusive and irreducible coupling matrix, and some criteria and corollary are derived to guarantee the network stability. Simulated examples are provided by using the chaotic Lorenz systems and Chua's circuit systems as nodes of the dynamical network, and the effectiveness of the proposed impulsive control are demonstrated finally.
The synthesis of biological molecules in the universe
Authors: Nigel Aylward
Venue: Proceedings of the international conference on Computational and information science 2009 (2009)

Theoretical chemistry is applied to describe in detail the formation of reactive intermediates in a primeval atmosphere composed of hydrogen, carbon monoxide and ammonia that at a suitable temperature could equilibrate to form a cascade of the biological molecules that allow molecular evolution. Of particular importance is the formation of porphin that can act as a powerful catalyst. The Faraday effect is invoked to explain the formation of the chirality of the L-amino-acids and D-sugars. Also described is the formation of the information molecules, the nucleic acid bases, the nucleosides, nucleotides and their polymerization to RNA and DNA. The formation of the terpenes allows the further formation of the glycerides. This atmosphere also leads to the formation of the vitamins. Most of the reactions appear to be exothermic except condensations involving carbon monoxide or ammonia. The reactions have been shown to be feasible from the overall enthalpy changes in the ZKE approximation at the HF and MP2 /6-31G* level.

Two Issues for an Ambient Reminding System: Context-Awareness and User Feedback
Authors: Nadine Richard, Seiji Yamada
Venue: Proceeding of the 2007 conference on Advances in Ambient Intelligence (2007)

Busy people would benefit from ambient, adaptive tools for reminding them what they have to do, depending on various contextual parameters. We are developing an adaptive and expressive agent, which learns when and how to notify users about self-assigned tasks and events. In this paper, we focus on two crucial issues for such a system: the selection of the input data set, and the design of an appropriate mechanism to get user feedback without being too intrusive. We describe in particular the inputs that encapsulate the current context of the agent: relative temporal distances, historical information about reminders and categories, and the context of both the user and the hosting device.
Application-specific quality of service constraint design in wireless sensor networks
Authors: Dharma P. Agrawal
Venue:  (2008)

A Wireless Sensor Network (WSN) is usually made up of hundreds or thousands of small sensors, for monitoring environmental changes or events in a given field. On the one hand, a WSN offers the advantages of self-organization, cost effectiveness, ease of deployment, and is widely applied in a broad range of military and civil applications. On the other hand, it has the limitations of low data rate, limited computing power, small sensing range, small transmission range, and limited battery power. Therefore, it is imperative to examine the fundamental limits and associated features of a WSN in performing its tasks. It can provide adequate guidelines in building a WSN with satisfactory Quality of Service (QoS).WSNs are usually deployed for various applications, and different applications may have different requirements. A general purpose WSN design can not fulfill the needs of all applications. Therefore, satisfying application-specific QoS WSN design is of paramount importance for practical sensor deployments. The aim of this dissertation is to outline the application-specific QoS constraints, and establish relationships between the QoS and the underlying network parameters. By analyzing and identifying the tradeoffs among them, optimal network parameters can be determined to direct practical WSN design. The topics covered in this dissertation include cost/energy efficient deployment in lattice WSNs, intrusion detection in heterogeneous random WSNs, intrusion detection in Gaussian distributed WSNs, range-free localization algorithm, and hops-based sleep scheduling algorithm. Directions for future works have also been outlined.
Multilingual and Localization Support for Ontologies
Authors: Mauricio Espinoza, Asunción Gómez-Pérez, Elena Montiel-Ponsoda
Venue: Proceedings of the 6th European Semantic Web Conference on The Semantic Web: Research and Applications (2009)

This demo proposal aims at providing support for the localization of ontologies, and as a result at obtaining multilingual ontologies. We briefly present an advanced version of LabelTranslator, our system to localize ontology terms in different natural languages. The current version of the system differs from previous works reported in [1,2] in that it relies on a modular approach to store the linguistic information associated to ontology terms. Additionally, it uses a synchronization method to maintain the conceptual and linguistic information updated.

Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

This study is both a qualitative and a quantitative approach of the nonlinear vibrations of the mechanical elastic systems with polynomial damping. It gives the physical and mathematical modelling and numerical simulation of the dynamics of one degree of freedom mechanical systems and shows the diagrams of the curves of different characteristics (amplitude, displacement, power) function of the polynomial coefficients of damping. It also shows the variation of the same characteristics function of the frequency of the harmonic force of excitation. The numerical simulation has done with the data of real technological equipment: an industrial conveyor driven by inertial vibrator which has tested in site by the specialists of The Research Centre of Machines, Mechanic and Technological Equipments - MECMET.
