Reducing Noise in Labels and Features for a Real World Dataset: Application of NLP Corpus Annotation Methods
Authors: Rebecca J. Passonneau, Cynthia Rudin, Axinia Radeva, Zhi An Liu
Venue: Proceedings of the 10th International Conference on Computational Linguistics and Intelligent Text Processing (2009)

This paper illustrates how a combination of information extraction, machine learning, and NLP corpus annotation practice was applied to a problem of ranking vulnerability of structures (service boxes, manholes) in the Manhattan electrical grid. By adapting NLP corpus annotation methods to the task of knowledge transfer from domain experts, we compensated for the lack of operational definitions of components of the model, such as serious event. The machine learning depended on the ticket classes, but it was not the end goal. Rather, our rule-based document classification determines both the labels of examples and their feature representations. Changes in our classification of events led to improvements in our model, as reflected in the AUC scores for the full ranked list of over 51K structures. The improvements for the very top of the ranked list, which is of most importance for prioritizing work on the electrical grid, affected one in every four or five structures.

Development of an agent-based system for manufacturing control and coordination with ontology and RFID technology
Authors: Ruey-Shun Chen, Mengru (Arthur) Tu
Venue: Expert Systems with Applications: An International Journal (2009)

Integrating physical objects with the corresponding enterprise applications any time any where is the essential issue for a real-time enterprise. This study proposes a multi-agent system framework called agent-based manufacturing control and coordination (AMCC) system, a agent-based framework using ontology and RFID technology to monitor and control dynamic production flows and also to improve the traceability and visibility of mass customization manufacturing processes. The capabilities offered by multi-agent systems to respond to RFID events in real-time and a broad class of agent design and coordination issue regarding just in time (JIT) and just in sequence (JIS) manufacturing processes are also exploited in this study. To validate the proposed framework, case study of a bicycle manufacturing company is used to demonstrate how the proposed framework can benefit its JIT production. Finally, an example prototype system is implemented to demonstrate the concept of the proposed framework.
Brief paper: Optimal allocation of heterogeneous resources in cooperative control scenarios
Authors: Brandon J. Moore, Jorge Finke, Kevin M. Passino
Venue: Automatica (Journal of IFAC) (2009)

This paper introduces a mathematical framework for the study of resource allocation problems involving the deployment of heterogeneous agents to different teams. In this context, the term heterogeneous is used to describe classes of agents that differ in the basic functions they can perform (e.g., one type of agent searches for targets while another type engages those targets). The problem is addressed in terms of optimization using concepts from economic theory and the proposed algorithm was designed to ensure asymptotic stability of the optimal solution.
Motivated by information: information about online collective action as an incentive for participation
Authors: Judd Antin
Venue: Proceedings of the ACM 2009 international conference on Supporting group work (2009)

This paper describes research focused on understanding the relationships between operational knowledge about how online collective action systems work and participation in those systems. Specifically, I use qualitative interviews to examine knowledge about online systems that form public goods, questioning whether the notions of public goods and social dilemmas are relevant and meaningful for individuals making real-world participation decisions. This paper also describes concurrent experimental research focused on exploring the relationship between knowledge about one's own and others' competence to contribute to collective goals as a factor in participation decisions.
Experimenting Advanced Visualization in the Operational Context of Transportation Networks: The VENN Project
Authors: J. Assfalg, E. Vicario, P. Neel, J. M. Tanneau
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

Large transportation networks (e.g., electric power and telephone traffic networks) require continuous supervision to ensure safe and economical operation. Humans involved in this task are requested to provide continuous and real-time feedback to an unpredictable system on the basis of a large and heterogeneous information volume. Effective visualization is an essential component to keep the pace in the current practice and open the way to new tasks of increasing complexity.Due to a number of "good reasons", mainly concerned with critical requirements of availability and reliability, but also with the need of a high degree of users' control on the system, the evolution of human computer interfaces in this context is quite slow and conservative. The state of the art is thus still in the move between tabular alphanumeric displays and 2D graphic WIMP (Windows Icons Menus Pointers) interfaces, and by far from a full exploitation of current means provided by multimedia and graphics technology.The main objective of the VENN (Virtual Environment for Network Navigation) project is to investigate and experiment applicability of advanced visualization techniques, and notably of 3D graphics, in the operational context of the control room of dispatching centers of electricity power and telephone traffic transportation networks. Results of the research are expected to promote industrial practice by highlighting directions of development for a next generation of user interfaces for the supervision of transportation networks.
Gene Expression Programming Based on Subexpression Library and Clonal Selection
Authors: Siqing Xue, Jie Wu
Venue: Proceedings of the 3rd International Symposium on Advances in Computation and Intelligence (2008)

Gene expression programming (GEP) is a recently developed evolutionary computation method for model learning and knowledge discovery. Sometimes it is not easy when use GEP to solve too complex problem, so enhancing the algorithm learning capability is necessary. This paper proposes an immune principle based GEP algorithm (iGEP), which combines gene library and clonal selection algorithm. The gene library is composed of subexpressions of GEP expression selected from the process of evolution. The proposed algorithm introduces some new features, including the best subexpression of GEP expression is selected as the solution of the problem, and some segments of gene library are used for hypermutation and receptor editing. In terms of convergence rate and computational efficiency, the experimented results on some benchmark problems of the UCI repository show that iGEP outperforms the standard GEP.
Robust interconnect communication capacity algorithm by geometric programming
Authors: Jifeng Chen, Jin Sun, Janet Meilin Wang
Venue: Proceedings of the 2009 international symposium on Physical design (2009)

This paper proposes a new model for interconnect communication capacity in the presence of process variations. Different from previous research works, this model, for the first time, reveals the dependency of interconnect communication capacity on its parasitic parameters. A new method based on Uncertainty Ellipsoid Method (UEM) is applied to optimize the interconnect capacity considering random parameters variations. This new approach incorporates both spatial correlations of intra-die width and parameters variations in the optimization procedure. As is well known, process variation introduces perturbations in the transfer function of interconnect networks. The perturbed transfer function in turn causes variations in the Bit Error Rate (BER). Becoming random, the perturbed BER leads to a changing communication capacity. Based on robust communication theory, we propose a new capacity model which is a function of interconnect geometric parameters. With the help of Geometric Programming (GP) procedure, we use the new model to conduct optimization with regard to the design parameters. Experimental results show that the new model provides less than 7:3% mean square error in capacity prediction comparing with Monte-Carlo method. Based on this bit error value, GP technique is applied to determine the optimal solution, which in return guides the fabrication of interconnects.
Proceedings of the 2nd International Workshop on Systems and Networking Support for Health Care and Assisted Living Environments
Venue: International Workshop on Systems and Networking Support for Health Care and Assisted Living Environments (2008)

It is our pleasure to welcome you to the Second ACM SIGMOBILE International Workshop on Systems and Networking Support for Healthcare and Assisted Living Environments (HealthNet 08), co-located with ACM MobiSys 2008. We have put together an excellent technical program that we hope you will enjoy, and that you will be able to take advantage of the diverse group of people that have come together for HealthNet 08. The motivation for creating the first HealthNet workshop in 2007 has not changed. We still face daunting challenges as the world's population grows older and healthcare costs continue to skyrocket. To address these challenges, it will be necessary to combine efforts not only from many areas of computer science, including networking, distributed systems, security, data management, HCI and middleware, but also from the medical community. To this end, we are delighted to present a keynote speaker, Dr. John Luo, who is a nationally recognized expert in mobile technology and medicine and who has received numerous awards for his pioneering use of technology in medicine. We hope this keynote will begin to break down the barriers between medicine and technology by bringing key researchers together in one forum and linking the two communities. We received a total of 23 submissions from 5 countries with papers from Asia, Canada, and the United States. These papers cover diverse topics from architectures and protocols to case-studies and real-world experiences. The selection of papers for this year's program was carried out by a 17 member international technical program committee. As a result of our review and discussion phase, a total of 6 full papers were accepted for presentation at the workshop, which corresponds to a competitive acceptance rate of 26%. Additionally, we accepted 4 demonstrations and 6 short papers to be presented as posters during the workshop.
Identification of ambiguous queries in web search
Authors: Ruihua Song, Zhenxiao Luo, Jian-Yun Nie, Yong Yu, Hsiao-Wuen Hon
Venue: Information Processing and Management: an International Journal (2009)

It is widely believed that many queries submitted to search engines are inherently ambiguous (e.g., java and apple). However, few studies have tried to classify queries based on ambiguity and to answer ''what the proportion of ambiguous queries is''. This paper deals with these issues. First, we clarify the definition of ambiguous queries by constructing the taxonomy of queries from being ambiguous to specific. Second, we ask human annotators to manually classify queries. From manually labeled results, we observe that query ambiguity is to some extent predictable. Third, we propose a supervised learning approach to automatically identify ambiguous queries. Experimental results show that we can correctly identify 87% of labeled queries with the approach. Finally, by using our approach, we estimate that about 16% of queries in a real search log are ambiguous.
Probabilistic Dependencies in Linear Hierarchies of Decision Tables
Authors: Wojciech Ziarko
Venue: Transactions on Rough Sets IX (2008)

The article is a study of probabilistic dependencies between attribute-defined partitions of a universe in hierarchies of probabilistic decision tables. The dependencies are expressed through two measures: the probabilistic generalization of the Pawlak's measure of the dependency between attributes and the expected certainty gain measure introduced by the author. The expected certainty gain measure reflects the subtle grades of probabilistic dependence of events. Both dependency measures are developed and it is shown how they can be extended from flat decision tables to dependencies existing in hierarchical structures of decision tables.
Development of applications with service-oriented architecture for grid
Authors: Vladimir Dimitrov
Venue: Proceedings of the 9th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing (2008)

Service-Oriented Architecture (SOA) is an approach for development of highly distributed integrated enterprise applications. Development of SOA applications needs of: process orchestration software; mediation software for message exchange; and repositories for registration and discoveries of services. Grid is service-oriented; it has repositories for service definition and discovery; but still there are no wide accepted mechanisms for orchestration and mediation.

Authors: Yi-Fan Wang, Ding-An Chiang, Mei-Hua Hsu, Cheng-Jung Lin, I-Long Lin
Venue: Expert Systems with Applications: An International Journal (2009)

A major concern for modern enterprises is to promote customer value, loyalty and contribution through services such as can help establish a long-term, honest relationship with customers. For purposes of better customer relationship management, data mining technology is commonly used to analyze large quantities of data about customer bargains, purchase preferences, customer churn, etc. This paper aims to propose a recommender system for wireless network companies to understand and avoid customer churn. To ensure the accuracy of the analysis, we use the decision tree algorithm to analyze data of over 60,000 transactions and of more than 4000 members, over a period of three months. The data of the first nine weeks is used as the training data, and that of the last month as the testing data. The results of the experiment are found to be very useful for making strategy recommendations to avoid customer churn.
Design for a common world: On ethical agency and cognitive justice
Authors: Maja Velden
Venue: Ethics and Information Technology (2009)

The paper discusses two answers to the question, How to address the harmful effects of technology? The first response proposes a complete separation of science from culture, religion, and ethics. The second response finds harm in the logic and method of science itself. The paper deploys a feminist technoscience approach to overcome these accounts of neutral or deterministic technological agency. In this technoscience perspective, agency is not an attribute of autonomous human users alone but enacted and performed in socio-material configurations of people and technology and their `intra-actions'. This understanding of agency is proposed as an alternative that opens up for the reconfiguration of design and use for more ethical effects, such as the cultivation of cognitive justice, the equal treatment and representation of different ways of knowing the world. The implication of this approach is that design becomes an adaptive and ongoing intra-active process in which more desirable configurations of people and technology become possible.
Developing embodied agent-based user interface by using interactive drama markup language
Authors: Zeng-Wei Hong, Kai-Yi Chin, Jim-Min Lin
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

Current researches of ECA-based user interfaces focus on how to script the behaviors of ECAs to resemble a real person, such as VHML, CML, AML, MPML, TelMeA, etc. They propose high-level scripting languages and development kits to support users scripting ECA-based user interfaces. However, we think that a scripting language must be concerned about creating ECA animation and user interfaces of the underlying software application. In other words, an appropriate ECA markup language should enable users to create avatars and represent layout of typical user interfaces with simple widgets, for example buttons. In this paper, we propose a XML-based interactive drama markup language (IDML) that allows users to create ECA-based user interfaces and GUIs with a set of buttons. Furthermore, IDML uses the concept of Interactive drama to create branching narrations that enables the audience to affect an ECA's behaviors when the audience interacts with the ECA, and enables the ECA will present different dialogue according to the audience's action. In order to give the general user's relief from learning XML, we design an authoring tool to provide visual windows consisted of GUI widgets to facilitate generations of interactive dramas in IDML.
A New Non-Linear Algorithm for 3D Reconstruction from Straight-line Optical Flow
Authors: Zhen Chen, Ming Li, Shao-feng Jiang, Shui-gen Wei, Yu Wang
Venue: Proceedings of the 2009 International Asia Conference on Informatics in Control, Automation and Robotics (2009)

This paper presents a new mathematical definition of straight-line optical flow. By using 21 straight-line optical flows in 3 consecutive image frames, a set of equations about 3D motion parameters are established to obtain 12 motion parameters of 3D object and coordinates of the 3D straight line. Usually, it is difficult to find the 21 straight lines on correspondence. In this paper, a minimum of 6 straight-line optical flows in 3 consecutive image frames is required to obtain 12 motion parameters of 3D object and coordinates of the 3D straight line, by solving non-linear equations. With the parameters and coordinates a 3D scene can be reconstructed.
Attribute-Based Ranking and Selection of Robots for Task Assignment
Authors: Bibhuti Bhusan Choudhury, Bibhuti Bhusan Biswal, Rabindra Narayan Mahapatra
Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

The selection of robot for a particular application is a critical issue and it depends on large number of parameters. With changing product design parameters, improving robot technology the problem of robot selection has been of concern to users. This problem has become more difficult in recent years due to increasing complexity, available features, and facilities offered by different robots. A systematic procedure is developed in this work for selection of robot manipulators based on their attributes. This procedure can be used to standardize the robot selection procedure when the user needs to use the robot for a particular application. Subsequently, the selection procedure proceeds to rank the alternatives in the shortlist by employing the attribute based specification method. This is an attempt to create an exhaustive procedure by identifying maximum possible number of attributes. The coding scheme and the ranking procedures are illustrated with example.
A constant-density approach for incompressible multi-phase SPH
Authors: X. Y. Hu, N. A. Adams
Venue: Journal of Computational Physics (2009)

A constant-density approach, which corrects intermediate density errors by adjusting the half-time-step velocity with exact projection, is proposed for the multi-phase SPH method developed in our previous work [X.Y. Hu, N.A. Adams, An incompressible multi-phase SPH method, J. Comput. Phys. 227 (2007) 264-278]. As no prescribed reference pressure is required, the present approach introduces smaller numerical viscosity and allows to simulate flows with unprecedentedly high density ratios by the projection SPH method. Numerical examples for Taylor-Green flow, capillary waves and for Rayleigh-Taylor instability are presented and compared to theoretical solutions or references from the literature.
Sum-Product Decoding of BCH Codes
Authors: Haruo Ogiwara, Kyouhei Shimamura, Toshiyuki Shohon
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper proposes methods to improve soft-input and soft-output decoding performance of BCH codes by sum-product algorithm (SPA). A method to remove cycles of length four (RmFC) in the Tanner graph has been proposed. However, the RmFC can not realize good decoding performance for BCH codes which have more than one error correcting capability. To overcome this problem, this paper proposes two methods. One is to use a parity check matrix of the echelon canonical form as the starting check matrix of RmFC. The other is to use a parity check matrix that is concatenation (ConC) of multiple parity check matrices. For BCH(31,11,11) code, SPA with ConC realizes Eb/No 3.7 dB better at bit error rate 10-5 than the original SPA, and 3.1 dB better than the SPA with only RmFC.
Analysis and Identification of Wiener-Hammerstein System in Frequency Domain Using Two-Tone Measurements for Nonlinear RF Transmitters
Authors: Hyunchul Ku
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper presents analysis and identification method of Wiener-Hammerstein system to characterize a nonlinear RF transmitter in fundamental frequency zone. A two-tone signal is used to analyze and identify a Wiener-Hammerstein model. A RF signal is converted to baseband-equivalent complex signal, and Wiener-Hammerstein model is considered to have a baseband equivalent complex polynomial and linear filters. For a two-tone input signal, closed form descriptions of the output signal in the time domain and frequency domain are developed using a newly suggested nonlinearly modulated two-tone phasors (NMTP). The relationship between frequency terms of input and output signals in RF transmitters are represented with linear matrix-vector equation based on NMTP analysis. An advantage of the proposed method is its simplicity using closed form analysis and linear approximation. In addition, we can model a wideband system with relatively narrowband measurements by sweeping two-tone signal. The prediction of spectral regrowth and the predistortion performance for WiBro 1FA signal demonstrate the validity of the proposed approach in identifying the nonlinear RF transmitters.
