Proceedings of the 22nd international conference on Machine learning
Venue: ACM International Conference Proceeding Series; Vol. 119 (2005)

This volume, which is also available online from http://www.machinelearning.org, contains the papers accepted for presentation at ICML-2005, the 22nd lnternational Conference on Machine Learning, which was held at the University of Bonn in Germany from August 7 to August 11, 2005. ICML is the annual conference of the lnternational Machine Learning Society (IMLS), and forms an international forum for the discussion and presentation of the latest results in the field of machine learning. This year, ICML was co-located with the 15th lnternational Conference on Inductive Logic Programming (ILP-2005), the proceedings of which are published by Springer Verlag in a separate volume. The papers in this volume were selected on the basis of a thorough review process. In the first round of reviewing, three program committee members produced individual reviews for a paper. Authors then had the opportunity to view those reviews and submit an author's reply to the reviewers. Led by the responsible area chair, the reviewers then engaged in a discussion about the paper, ultimately leading to the decision by the program chairs. In sum, of the 491 papers that were initially submitted, 62 were accepted immediately, and a further 81 were conditionally accepted and reconsidered after resubmission in a second round of reviewing. Of those 81 conditionally accepted papers, 72 were finally accepted, leading to a total of 134 accepted papers, which translates into an acceptance rate of 27.3 %. The author reply was a new feature of ICML this year, while the option of working with conditional accepts has already become a tradition. In addition to the presentations of the accepted papers, the ICML program included several other features. On the first and last day of the conference, 11 workshops and 6 tutorials on current topics of machine learning were held. For many of these, proceedings and/or presentation materials are available online from the ICML website. The other days of the conference each featured an invited talk by a prominent researcher as a program highlight. We were delighted that Johannes Gehrke of Cornell University, Michael Jordan of the University of California at Berkeley, and Gerhard Widmer of the University of Linz in Austria, agreed to deliver an invited talk. The abstracts of their talks are also published as part of these proceedings. Continuing a long standing tradition at ICML, all papers presented in a talk at the conference were also exhibited at evening poster sessions, giving everyone ample time to discuss the results in depth. In order to emphasize the co-location with ILP-2005, the program contained joint elements in both invited speakers, paper sessions, poster sessions, and tutorials. As usual, the scientific program was complemented by a social program, this time featuring an excursion to the scenic surroundings of the city of Bonn. During the conference best paper and best student paper awards were presented, the former being sponsored by NICTA, the later by the Machine Learning Journal.
Evaluation of subjective video quality of mobile devices
Authors: Satu Jumisko-Pyykkö, Jukka Häkkinen
Venue: Proceedings of the 13th annual ACM international conference on Multimedia (2005)

Subjectively perceived video quality is a critical factor when adopting new mobile video applications. When video is used in mobile networks the most important requirements are related to low bitrates, framerates and the screen size of mobile device. In two tests we investigated the effects of codecs and combinations of audio and video streams with low bitrates and different contents on the perceived video quality of mobile devices. The first test showed that the codec H.264 produced the most satisfying video quality, but the quality was not high enough for the presentation of textual information. In the second test, the audio-video ratio 32/128kbps was found to be the most pleasant, but there were content dependent variations.
A Rail-to-Rail I/O Operational Amplifier with 0.5% gm Fluctuation Using Double P-channel Differential Input Pairs
Authors: Zhiyuan Li, Mingyan Yu, Jianguo Ma
Venue: Proceedings of the 19th International Conference on VLSI Design held jointly with 5th International Conference on Embedded Systems Design (2006)

A new operational amplifier working with supply voltages 1.8V has been designed in SMIC 0.18- µm CMOS technology. The p-channel differential input pair and a level-shift p-channel differential input pair operate in weak inversion. A constant trans-conductance (within 0.5% of maximum fluctuation) based on current mode is ensured for the entire input common mode range by a simple and novel small signal control circuit that offsets second-order effects under constant tail current, such as variation of the slope factors of weak inversion transistors and finite output resistance. The class AB output stage biased by a new cross-coupling voltage level shifter has a full voltage swing and better high frequency performance. This circuit provides a 46MHz gain bandwidth for a power consumption of 0.6mW with 5pF load.
Performance analysis of network source coding algorithms
Authors: Zhen Zhang
Venue:  (2005)

The field of network source coding treats data compression in any environment comprising more than one encoder, more than one decoder, or both. Examples of network source codes include multi-resolution, multiple descriptions, multiple access, side information, and broadcast codes. Recent results developed in the literature include theoretical analysis and code design algorithms for both lossless and lossy algorithm in a variety of network environments. An asymptotically optimal lossy source coding algorithm will approach the rate-distortion limit as the encoding block length tends to infinity. For such an algorithm, when coding complexity is taken into account, the performance is measured by the redundancy of the algorithm which is defined as the difference between its expected performance and the rate-distortion function of the source. Motivated by the recent results in the redundancy of source coding for block codes and trellis codes, this dissertation has investigated the distortion redundancy of multi-resolution coding algorithms for successively refinable sources, the redundancy of multiple description coding algorithms in the case of no excess rate for the joint description, as well as the redundancy of coding time-descrete stationary Gaussian source after transformation and the redundancy estimation of universal trellis coding algorithms. Results in causal encoding of Markov source with its application to feedback networks are also included.The given theoretical investigations into network source code performance will provide valuable insight into code design. On the other hand, the redundancy analysis that we developed is a practical generalization of the Shannon source coding theorem to the more concrete cases.
A city guide agent creating and adapting individual sightseeing tours
Authors: Klaus ten Hagen, Marko Modsching, Ronny Kramer
Venue: Proceedings of the 5th International Conference on Intelligent Systems Design and Applications (2005)

Tourists deciding to explore a destination spontaneously and unprepared will have to walk and search on their own. This kind of investigation can be very uncomfortable as it often ends up in disarrangement. With today's agent technology, tourists can have their own intelligent guide taking care of the whole tour organisation and execution in time. This is the main objective of the Dynamic Tour Guide (DTG) - a mobile agent that selects attractions, plans an individual tour, provides navigational guidance and offers location based interpretation. Over all it consistently adapts the tour to a tourist's specific behaviour in order to provide any possible support via a mobile device.
Speaker Recognition Using Features Derived from Fractional Fourier Transform
Authors: Jinfang Wang, Jinbao Wang
Venue: Proceedings of the Fourth IEEE Workshop on Automatic Identification Advanced Technologies (2005)

As the generalization of the classical Fourier transform, fractional Fourier transform(FRFT) is introduced into the field of speaker recognition in this paper. The individual feature sets derived from fractional Fourier transform achieve the excellent recognition success rate which goes up to the extent a little higher than the counterparts of the classical MFCC parameters when applied in the GMM classifiers. In addition, the computation efficiency of the feature extraction process arrives at the acceptable level which completely matches the one of MFCC parameter acquirement.
C(I)IP Task Description and a Proposal for a Substitute of National C(I)IP Policies
Authors: Bernhard M. Hammerli
Venue: Proceedings of the First IEEE International Workshop on Critical Infrastructure Protection (2005)

The development of critical infrastructures in the past 20 years brought ICT into nearly every component, increased the complexity enormously, and centralized service production for cost optimization. The overall security level and crisis preparedness has decreased at the same time. Countermeasures in the form of C(I)IP plans are being discussed on political side and also from the technical side e.g. in the form of sector-specific cyber security and CERT efforts. However, in between these two ends C(I)IP middleware is missing. This paper proposes to approach the specification of this middleware through an Extraordinary Situation Service Level Agreement (ES SLA) mechanism, which defines key performance indicators (KPI) and parameters for good C(I)IP practice. The ES SLA is intended as a step in solving problems such as missing national C(I)IP policy, missing CI(I)IP middleware specification, lack of motivation to approach the C(I)IP task and an incomplete C(I)IP view of stakeholders. Moreover, procedures for KPI definition and perspectives on how ES SLA could work are given.
Ab-initio simulations on growth and interface properties of epitaxial oxides on silicon
Authors: C. J. Först, C. R. Ashman, K. Schwarz, P. E. Blöchl
Venue: Microelectronic Engineering (2005)

The replacement of SiO2 by so-called high-k oxides is one of the major challenges for the semiconductor industry to date. Based on electronic structure calculations and ab-initio molecular dynamics simulations, we are able to provide a consistent picture of the growth process of a class of epitaxial oxides around SrO and SrTiO3. The detailed understanding of the interfacial binding principles has also allowed us to propose a way to engineer the band-offsets between the oxide and the silicon substrate.
3G Mobile Phone Applications in Telemedicine - A Survey
Authors: Kazuaki Yamauchi, Wenxi Chen, Daming Wei
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

In this paper, we will review current 3G mobile phone applications in telemedicine. Mobile phones are the backbone of mobile communications and have experienced explosive growth. 3G mobiles provide a next generation mobile phone service that aims to offer high-speed 2Mb/s communication using high transmission efficiency in the high frequency 2GHz band. This offers a groundbreaking way to use mobile phones. Mobile phone service became ubiquitously available throughout Japan as 3G mobile phone offers major advantages for interactive video traffic. With the emergence of mobile phone networks, a number of systems which use mobile phones to transfer vital signs such as electrocardiogram (ECG) and heart rate have increased instead of early mobile medical system using satellites to establish communications between remote sites and base hospitals. Applications of mobile phone have become diversified and derive many services. It is predicted that the proportion of 3G mobile phones would overtake that of 2G mobile phones by 2006.
Low Power Bluetooth for Headset Applications, invited
Authors: Christian Cojocaru
Venue: Proceedings of the Fifth International Workshop on System-on-Chip for Real-Time Applications (2005)

Bluetooth headsets demand high radio performance at extreme low power consumption. A Bluetooth (BT) transceiver implemented in a 0.5 ..m BiCMOS process is supplied at 1.8V and consumes less than 24mA when receiving and less than 18mA when transmitting. The receiver has -91dBm sensitivity and best-in-class blocker performance. Architecture, circuits and radio performance are reviewed. A Bluetooth headset based on this transceiver consumes 12mA in a 64kb/s HV3 voice link, has 10h talk time and weighs only 14g.
Configuring and managing a large-scale monitoring network: solving real world challenges for ultra-low-powered and long-range wireless mesh networks
Authors: Christophe Dugas
Venue: International Journal of Network Management (2005)

In creating wireless networking solutions suitable for deployment in harsh, unpredictable and widespread environments, we were confronted with a series of problems as yet unsolved by commercially available technologies. The purpose of this article is to describe how we addressed mission-critical customer requirements by developing a wireless technology explicitly for devices in ultra-low-power (ULP) and long-range wireless mesh networks. The key end-points in our target implementation are battery-operated devices located in hard-to-reach places, but which are nonetheless expected to offer a lifespan of several years without human intervention. We provide an overview of the technical requirements for building ULP networks, with a focus on configuration and management (including patent pending self-configuration and dynamic-routing features). This is followed by a case study of an existing 25,000-node wireless network deployed for an automatic meter reading (AMR) solution, and examples of provisioning individual nodes in complex real-world networks.
A Multi-Thread Processor Architecture Based on the Continuation Model
Authors: Takanori Matsuzaki, Satoshi Amamiya, Masaaki Izumi, Makoto Amamiya
Venue: Proceedings of the Innovative Architecture on Future Generation High-Performance Processors and Systems (2005)

We are developing the Fuce processor based on the dataflow computing model. Fuce means FUsion of Communication and Execution. In order to execute many threads with multiple thread execution units efficiently, the Fuce processor executes multiple threads using the exclusive multi-thread execution model. The core concept of the exclusive multi-thread execution model is continuation based multi-thread execution, which is derived from dataflow computing. The Fuce processor aims to fuse the intra-processor execution and inter-processor communication. The Fuce processor unifies processing inside the processor and communication with processors outside as events, and executes the event as a thread. In this paper, we introduce the architecture of the Fuce processor and evaluate the concurrency performance of a Fuce processor which we described in VHDL. As a result, we understood that the processor has concurrency capability when there is sufficient thread level parallelism.
Smart problem solving environment for medical decision support
Authors: Andrei Petrovski, John McCall
Venue: Proceedings of the 2005 workshops on Genetic and evolutionary computation (2005)

This paper presents a medical problem solving environment (PSE) designed for modelling, simulation, and optimisation of clinical cancer chemotherapy. In order to find optimal chemotherapeutic treatments, two population-based evolutionary algorithms -- Genetic Algorithms and Particle Swarm Optimisation -- have been applied, which can use web services and grid computing to evaluate potential solutions in a distributed and customizable manner. The versatility and robustness of these algorithms make the suggested problem solving environment scalable and adaptable to other problem domains.
Chained In-Order/Out-of-Order DoubleCore Architecture
Authors: Miquel Pericas, Adrian Cristal, Ruben Gonzalez, Daniel A. Jimenez
Venue: Proceedings of the 17th International Symposium on Computer Architecture on High Performance Computing (2005)

Complexity is one of the most important problems facing microarchitects. It is exacerbated by the application of optimizations, by scaling to higher issue widths and, in general, by increasing the size of microprocessor structures. This paper presents a new microarchitecture, the Chained In-Order/Out-of-Order DoubleCore Architecture (CIO2), designed to attack the problems of complexity and energy. The CIO2 architecture reorganizes the microarchitecture using the concepts of a centralized register file and the Future File. The resulting architecture decouples that program state from the execution units. The simplicity of the architecture enables the implementation of three optimizations with little effort: register file banking, writeback filtering and instruction pre-execution. These optimizations allow a reduction of up to 75% in register file energy consumption. Instruction pre-execution further allows around 40% of all integer instructions to execute in the in-order front-end, considerably reducing the activity of the power-hungry issue queues in the out-of-order back-end. Moreover, these improvements are achieved with a negligible performance loss.
Combined Mobility between H.323 Multimedia Systems and GPRS/IMT2000 Networks: Architecture & QoS Aspects
Authors: Leo Lehmann
Venue: Proceedings of the Joint International Conference on Autonomic and Autonomous Systems and International Conference on Networking and Services (2005)

This paper describes a reference architecture which enables a H.323 user, to get access to H.323 based Multimedia services also outside her/his corporate network domain via an IMT2000 based mobile network. The appropriate mechanisms to handle the mobility management between an H.323 based environment and IMT2000 based mobile networks (combined mobility) are explained. The article also considers the appropriate requirements to achieve defined conditions for an end to end service with a guaranteed quality. Furthermore the demand of corresponding Service Level Agreements between all involved parties is identified.
SmallConnection: designing of tangible communication media over networks
Authors: Hideaki Ogawa, Noriaki Ando, Satoshi Onodera
Venue: Proceedings of the 13th annual ACM international conference on Multimedia (2005)

The concept of "SmallConnection (abbr. SC)" is creating easy to operate tangible media for communication over networks. Focusing on the scenario where two intimate people live in distant places, we developed communication media that can be handled like tools, and can convey faint information such as light, wind and touch through the use of a robot technology. The goal of this project is to propose and prototype new media design for communication between two people. Through working 3 products derived from SC, we hope to widely propose a?future communication design using multimedia.
Model-Driven Visual Requirements Engineering
Authors: Helge Solheim, Frank Lillehagen, Sobah A. Petersen, Havard Jorgensen, Maria Anastasiou
Venue: Proceedings of the 13th IEEE International Conference on Requirements Engineering (2005)

This paper describes the requirements handling process of a set of research projects, the ATHENA IP, and how this process is supported by modeling and visualizing requirement structures. First, users and external stakeholders register requirements through easy-to-use web interfaces. Then developers and managers utilize an integrated modeling tool for visual classification, analysis, elicitation, and selection of requirements. In this paper, we show how advanced visualization techniques improve and support state-ofthe- art within requirements handling. This requirement handling system was first applied in the UEML project, and a variant of it is in day-today use by a commercial software vendor and its customers. We finally describe the overall experiences from use of the system.
An enhanced property of factorizing codes
Authors: Clelia De Felice
Venue: Theoretical Computer Science (2005)

The investigation of the factorizing codes C, i.e., codes satisfying Schützenberger's factorization conjecture, has been carried out from different viewpoints, one of them being the description of structural properties of the words in C. In this framework, we can now improve an already published result. More precisely, given a factorizing code C over a two-letter alphabet A = {a, b}, it was proved by De Felice that the words in the set C1 = C ∩ a*ba* could be arranged over a matrix related to special factorizations of the cyclic groups. We now prove that, in addition, these matrices can be recursively constructed starting with those corresponding to prefix/suffix codes.
Hidden Markov Models Combining Discrete Symbols and Continuous Attributes in Handwriting Recognition
Authors: Hanhong Xue Venu Govindaraju
Venue: IEEE Transactions on Pattern Analysis and Machine Intelligence (2006)

Prior arts in handwritten word recognition model either discrete features or continuous features, but not both. This paper combines discrete symbols and continuous attributes into structural handwriting features and model, them by transition-emitting and state-emitting hidden Markov models. The models are rigorously defined and experiments have proven their effectiveness.
X-Tolerant Test Response Compaction
Authors: Subhasish Mitra, Steven S. Lumetta, Michael Mitzenmacher, Nishant Patil
Venue: IEEE Design Test (2005)

Larger, denser designs lead to more defects; higher quality requirements and new test methods lead to an explosion in test data volume. Test compression techniques attempt to do more testing with fewer bits. This article summarizes one such method, X-compact, which addresses how unknowns, the bane of compression and logic BIST techniques, are eliminated.
Synchronizability of Conversations among Web Services
Authors: Xiang Fu Tevfik Bultan, Jianwen Su
Venue: IEEE Transactions on Software Engineering (2005)

We present a framework for analyzing interactions among Web services that communicate with asynchronous messages. We model the interactions among the peers participating in a composite Web service as conversations, the global sequences of messages exchanged among the peers. This naturally leads to the following model checking problem: Given an LTL property and a composite Web service, do the conversations generated by the composite Web service satisfy the property? We show that asynchronous messaging leads to state space explosion for bounded message queues and undecidability of the model checking problem for unbounded message queues. We propose a technique called synchronizability analysis to tackle this problem. If a composite Web service is synchronizable, its conversation set remains the same when asynchronous communication is replaced with synchronous communication. We give a set of sufficient conditions that guarantee synchronizability and that can be checked statically. Based on our synchronizability results, we show that a large class of composite Web services with unbounded message queues can be verified completely using a finite state model checker such as SPIN. We also show that synchronizability analysis can be used to check the realizability of top-down conversation specifications and we contrast the conversation model with the Message Sequence Charts. We integrated synchronizability analysis to a tool we developed for analyzing composite Web services.
Singular Homoclinic Bifurcations in a Planar Fast-Slow System
Authors: Feng Xie, Maoan Han, Weijiang Zhang
Venue: Journal of Dynamical and Control Systems (2005)

In this paper, a planar fast-slow system is considered. The existence of homoclinic orbits to a hyperbolic saddle or a saddle-node are proved by the rigorous mathematical analysis and geometric singular perturbation theory, and the corresponding bifurcation properties are analyzed. Moreover, the asymptotic approximations of curves of homoclinic orbits are obtained.
