To achieve smooth real-world interaction between people and computers, we developed a system that displays a three-dimensional
computer-graphic human-like image from the waist up (anthropomorphic software robot: hereinafter “robot”) on the display,
that interactively sees and hears, and that has fine and detailed control functions such as facial expressions, line of sight,
and pointing at targets with its finger. The robot visually searches and identifies persons and objects in real space that
it has learned in advance (registered space, which was our office in this case), manages the history information of the places
and times it found objects and/or persons, and tells the user, indicating their three-dimensional positions with line of sight
and its finger. It interactively learns new objects and persons with line of with their names and owners. By using this function,
the robot can engage in simple dialogue (do a task) with the user.

This paper proposes a new, efficient algorithm for extracting similar sections between two time sequence data sets. The algorithm,
called Relay Continuous Dynamic Programming (Relay CDP), realizes fast matching between arbitrary sections in the reference
pattern and the input pattern and enables the extraction of similar sections in a frame synchronous manner. In addition, Relay
CDP is extended to two types of applications that handle spoken documents. The first application is the extraction of repeated
utterances in a presentation or a news speech because repeated utterances are assumed to be important parts of the speech.
These repeated utterances can be regarded as labels for information retrieval. The second application is flexible spoken document
retrieval. A phonetic model is introduced to cope with the speech of different speakers. The new algorithm allows a user to
query by natural utterance and searches spoken documents for any partial matches to the query utterance. We present herein
a detailed explanation of Relay CDP and the experimental results for the extraction of similar sections and report results
for two applications using Relay CDP.

This paper describes a musical instrument identification method that takes into consideration the pitch dependency of timbres of musical instruments. The difficulty in musical instrument identification resides in the pitch dependency of
musical instrument sounds, that is, acoustic features of most musical instruments vary according to the pitch (fundamental
frequency, F0). To cope with this difficulty, we propose an F0-dependent multivariate normal distribution, where each element of the mean vector is represented by a function of F0. Our method first extracts 129 features (e.g.,
the spectral centroid, the gradient of the straight line approximating the power envelope) from a musical instrument sound
and then reduces the dimensionality of the feature space into 18 dimension. In the 18-dimensional feature space, it calculates
an F0-dependent mean function and an F0-normalized covariance, and finally applies the Bayes decision rule. Experimental results of identifying 6,247 solo tones of 19 musical instruments
shows that the proposed method improved the recognition rate from 75.73% to 79.73%.

This paper aims at constructing a music composition system that composes music by the interaction between human and a computer.
Even users without special musical knowledge can compose 16-bar musical works with one melody part and some backing parts
using this system. The interactive Genetic Algorithm is introduced to music composition so that users’ feeling toward music
is reflected in the composed music. One chromosome corresponds to 4-bar musical work information. Users participate in music
composition by evaluating composed works after GA operators such as crossover, mutation, virus infection are applied to chromosomes
based on the evaluation results. From the experimental results, it is found that the users’ evaluation values become high
over the progress of generations. That is, the system can compose 16-bar musical works reflecting users’ feeling.

We have developed a real-time gesture recognition system whose models can be taught by only one instruction. Therefore the
system can adapt to new gesture performer quickly but it can not raise the recognition rates even if we teach gestures many
times. That is because the system could not utilize all the teaching data. In order to cope with the problem, averages of
teaching data are calculated. First, the best frame correspondence of the teaching data and the model is obtained by Continuous
DP. Next the averages and variations are calculated for each frame of the model. We show the effectiveness of our method in
the experiments.

This paper proposes an automatic indexing method named PAI (Priming Activation Indexing) that extracts keywords expressing
the author’s main point from a document based on the priming effect. The basic idea is that since the author writes a document
emphasizing his/her main point, impressive terms born in the mind of the reader could represent the asserted keywords. Our
approach employs a spreading activation model without using corpus, thesaurus, syntactic analysis, dependency relations between
terms or any other knowledge except for stop-word list. Experimental evaluations are reported by applying PAI to journal/conference
papers.

When building a large and complex system, such as satellites, all sorts of risks have to be managed if it were to be successful.
For risks in the design of an artifact, various reliability analysis techniques such as FTA or FMEA have been employed in
the engineering domain. However, risks exist as well in the development process, and they could result in a failure of the
system. In this paper, we present an approach to discovering risks in development process by collecting and organizing information
produced during development process at low cost. We describe a prototype system called IDIMS, and show how it can be used
to discover risks from e-mail communications between developers. The motivation of our work is to overcome thecapture bottleneck problem, and utilize now wasted information to improve development process.

View-based approach for learning and recognition of 3D object and its pose detection was proved to be affective and efficient,
except its high learning cost. In this research, we propose a virtual learning approach which generates learning samples of
views of an object from its 3D view model obtained by motion-stereo method. From the generated learning sample views, features
of high-order autocorrelation are extracted, and discriminant feature spaces for object recognition and pose detection are
built. Recognition experiments on real objects are carried out to show the effectiveness of the proposed method.

In an artificial market approach with multi-agent systems, the static equilibrium concept is often used in market systems
to approximate continuous market auctions. However, differences between the static equilibrium concept and continuous auctions
have not been discussed in the context of an artificial market study. In this paper, we construct an artificial market model
with both of them, namely, the Itayose and Zaraba method, and show simple characteristic differences between these methods
based on computer simulations. The result indicates the further need to model the market system by studying artificial markets.

We propose a notion of a real-world knowledge medium by presenting our ongoing project to build a guidance system for exhibition
tours. In order to realize a knowledge medium usable in the real world, we focus on the context-awareness of users and their
environments. Our system is a personal mobile assistant that provides visitors touring exhibitions with information based
on their spatial/temporal locations and individual interests. We also describe an application of knowledge sharing used in
the actual exhibition spaces.

Chance discoveries for making decisions in complex real world 总被引:1,自引:0,他引:1
Yukio Ohsawa 《New Generation Computing》2002,20(2):143-163
Chance discovery is to become aware of a chance and to explain its significance, especially if the chance is rare and its
significance is unnoticed. This direction matches with various real requirements in human life. This paper presents the significance,
viewpoints, theories, methods, and future work of chance discovery. Three keys for the progress are extracted from fundamental
discussions on how to realize chance discovery: (1) communication, (2) imagination, and (3) data mining. As an approach to
chance discovery, visualized data mining methods are formalized as tools aiding chance discoveries on the basis of these keys.

This paper presents new object-spatial layout-route based hybrid map representation and global localization approaches using
a stereo camera. By representing objects as high-level features in a map, a robot can deal more effectively with different
contexts such as dynamic environments, human-robot interaction, and semantic information. However, the use of objects alone
for map representation has inherent problems. For example, it is difficult to represent empty spaces for robot navigation,
and objects are limited to readily recognizable things. One way to overcome these problems is to develop a hybrid map that
includes objects and the spatial layout of a local space. The map developed in this research has a hybrid structure that combines
a global topological map and a local hybrid map. The topological map represents the spatial relationships between local spaces.
The local hybrid map combines the spatial layout of the local space with the objects found in that space. Based on the proposed
map, we suggest a novel coarse-to-fine global localization method that uses object recognition, point cloud fitting and probabilistic
scan matching. This approach can accurately estimate robot pose with respect to the correct local space.

In this paper, we propose a framework for enabling for researchers of genetic algorithms (GAs) to easily develop GAs running
on the Grid, named “Grid-Oriented Genetic algorithms (GOGAs)”, and actually “Gridify” a GA for estimating genetic networks,
which is being developed by our group, in order to examine the usability of the proposed GOGA framework. We also evaluate
the scalability of the “Gridified” GA by applying it to a five-gene genetic network estimation problem on a grid testbed constructed
in our laboratory.

Management of telecommunication network requires quick, continuous and decentralized allocation of network bandwidth to various
sorts of demands. So as to achieve the efficient network resource allocation, this paper describes a market-based model combining
futures market with the agent-based approach. That is, utilization time is divided into many timeslots, and futures markets
in hereafter use of bandwidth are opened. In our model, all market participants (software agents) observe only market prices
and decide to buy or sell bandwidth trying to maximize their utilities over time so that they can secure enough network resources.
The authors discuss network resource allocation through simulation using the proposed model.

In this paper, we propose as a new challenge a public opinion channel which can provide a novel communication medium for sharing
and exchanging opinions in a community. Rather than simply developing a means of investigating public opinion, we aim at an
active medium that can facilitate mutual understanding, discussion, and public opinion formation. First, we elaborate the
idea of public opinion channels and identify key issues. Second, we describe our first step towards the goal using the talking
virtualized egos metaphor. Finally, we discuss a research agenda towards the goal.

Theaccumulation strategy consists of generalizing a function over an algebraic data structure by inclusion of an extra parameter, anaccumulating parameter, for reusing and propagating intermediate results. However, there remain two major difficulties in this accumulation strategy.
One is to determinewhere andwhen to generalize the original function. The other, surprisingly not yet receiving its worthy consideration, is how to manipulate
accumulations. To overcome these difficulties, we propose to formulate accumulations ashigher order catamorphisms, and provide several general transformation rules for calculating accumulations (i.e., finding and manipulating accumulations)
bycalculation-based (rather than a search-based) program transformation methods. Some examples are given for illustration.

An Efficient Support Vector Machine Learning Method with Second-Order Cone Programming for Large-Scale Problems 总被引:1,自引:1,他引:0
In this paper we propose a new fast learning algorithm for the support vector machine (SVM). The proposed method is based
on the technique of second-order cone programming. We reformulate the SVM's quadratic programming problem into the second-order
cone programming problem. The proposed method needs to decompose the kernel matrix of SVM's optimization problem, and the
decomposed matrix is used in the new optimization problem. Since the kernel matrix is positive semidefinite, the dimension
of the decomposed matrix can be reduced by decomposition (factorization) methods. The performance of the proposed method depends
on the dimension of the decomposed matrix. Experimental results show that the proposed method is much faster than the quadratic
programming solver LOQO if the dimension of the decomposed matrix is small enough compared to that of the kernel matrix. The
proposed method is also faster than the method proposed in (S. Fine and K. Scheinberg, 2001) for both low-rank and full-rank
kernel matrices. The working set selection is an important issue in the SVM decomposition (chunking) method. We also modify
Hsu and Lin's working set selection approach to deal with large working set. The proposed approach leads to faster convergence.

Recently, life scientists have expressed a strong need for computational power sufficient to complete their analyses within
a realistic time as well as for a computational power capable of seamlessly retrieving biological data of interest from multiple
and diverse bio-related databases for their research infrastructure. This need implies that life science strongly requires
the benefits of advanced IT. In Japan, the Biogrid project has been promoted since 2002 toward the establishment of a next-generation
research infrastructure for advanced life science. In this paper, the Biogrid strategy toward these ends is detailed along
with the role and mission imposed on the Biogrid project. In addition, we present the current status of the development of
the project as well as the future issues to be tackled.

AgentTeamwork is a grid-computing middleware system that dispatches a collection of mobile agents to coordinate a user job
over remote computing nodes in a decentralized manner. Its utmost focus is to maintain high availability and dynamic balancing
of distributed computing resources to a parallel-computing job. For this purpose, a mobile agent is assigned to each process
engaged in the same job, monitors its execution at a different machine, takes its periodical execution snapshot, moves it
to a lighter-loaded machine, and resumes it from the latest snapshot upon an accidental crash. The system also restores broken
inter-process communication involved in the same job using its error-recoverable socket and mpiJava libraries in collaboration
among mobile agents.
We have implemented the first version of our middleware including a mobile agent execution platform, error-recoverable socket
and mpiJava API libraries, a job wrapper program, and several types of mobile agents such as commander, resource, sentinel,
and bookkeeper agents, each orchestrating, allocating resources to, monitoring and maintaining snapshots of a user process
respectively. This paper presents AgentTeamwork’s execution model, its implementation techniques, and our performance evaluation
using the Java Grande benchmark test programs.
