A Statistical Model for Automatic Extraction of Korean Transliterated Foreign Words

引用

International Journal of computer Processing of Languages 2003年第1期16卷 41-62页

作者： JONG-HOON OH KEY-SUN CHOI Computer Science Division Department of EECS Korea Terminology Research Center for Language and Knowledge Engineering (KORTERM) Korea Advanced Institute of Science and Technology (KAIST) 373-1 Kusong-Dong Yusong-Gu Taejon 305-701 Korea

In this paper, we will describe a Korean transliterated foreign word extraction algorithm. In the proposed method, we reformulate the foreign word extraction problem as a syllable-tagging problem such that each syllable is tagged with a foreign syllable tag or a pure Korean syllable tag. Syllable sequences of Korean strings are modelled by Hidden Markov Model whose state represents a character with binary marking to indicate whether the syllable is part of a transliterated foreign word or not. The proposed method extracts a transliterated foreign word with high recall rate and precision rate. Moreover, our method shows good performance even with small-sized training corpora.

Informal presentations are a lightweight means for fast and convenient communication of ideas. People communicate their ideas to others on paper and whiteboards, which afford fluid sketching of graphs, words and other expressive symbols. Unlike existing authoring tools that are designed for formal presentations, we created SketchPoint to help presenters design informal presentations via freeform sketching. In SketchPoint, presenters can quickly author presentations by sketching slide content, overall hierarchical structures and hyperlinks. To facilitate the transition from idea capture to communication, a note-taking workspace was built for accumulating ideas and sketching presentation outlines. Informal feedback showed that SketchPoint is a promising tool for idea communication. Copyright 2003 ACM.

Modeling of motor control on manual tracking for developing a handmovement-compensation technique

Artificial Life and Robotics 2003年第3期7卷 112-117页

Skillful motor control by humans is achieved by the appropriate motor commands generating from the central nervous system. An internal model in the cerebellum may contribute to the realization of accurate motor control. In this work, a model of human motor control of manual tracking to move a visible target was constructed based on experimental data from a visual tracking test with normal healthy adults and with patients with cerebellar ataxia. A compensation method to improve the motor function of patients was also developed by using the model.

By employing the simple but robust Chorin Turkel preconditioning method, we ex- tend the widely used reactive Roe flux scheme to low speed applications. The derivations of the Chorin Turkel preconditioning for unsteady reacting flows is briefly introduced and a modified Roe flux expression similar to the original reactive Roe flux format is obtained for the first time. An axisymmetric confined methane-air laminar diffusion flame simulation with two-step global reaction mechanism is carried out using the scheme. An analysis shows results compare well with experimental measurements. © 2003 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.

Noise-induced unstable dimension variability and transition to chaos in random dynamical systems

引用

Physical Review E 2003年第2期67卷 026210-026210页

作者： Ying-Cheng Lai Zonghua Liu Lora Billings Ira B. Schwartz Department of Mathematics Center for Systems Science and Engineering Research Arizona State University Tempe Arizona 85287 Departments of Electrical Engineering and Physics Arizona State University Tempe Arizona 85287 Department of Mathematical Sciences Montclair State University Upper Montclair New Jersey 07043 Plasma Physics Division Naval Research Laboratory Code 6792 Washington DC 20375

Results are reported concerning the transition to chaos in random dynamical systems. In particular, situations are considered where a periodic attractor coexists with a nonattracting chaotic saddle, which can be expected in any periodic window of a nonlinear dynamical system. Under noise, the asymptotic attractor of the system can become chaotic, as characterized by the appearance of a positive Lyapunov exponent. Generic features of the transition include the following: (1) the noisy chaotic attractor is necessarily nonhyperbolic as there are periodic orbits embedded in it with distinct numbers of unstable directions (unstable dimension variability), and this nonhyperbolicity develops as soon as the attractor becomes chaotic; (2) for systems described by differential equations, the unstable dimension variability destroys the neutral direction of the flow in the sense that there is no longer a zero Lyapunov exponent after the noisy attractor becomes chaotic; and (3) the largest Lyapunov exponent becomes positive from zero in a continuous manner, and its scaling with the variation of the noise amplitude is algebraic. Formulas for the scaling exponent are derived in all dimensions. Numerical support using both low- and high-dimensional systems is provided.

A new procedure for registering brain MRI from different individuals with large anatomical differences is presented, and applied to the registration of images of patients with a brain tumor with an atlas. The key steps are the implantation of a synthetic tumor in the atlas and a novel robust image registration technique. Application of this procedure to the determination of abnormalities in the electrical activity of patients with brain tumors is presented as well.

Most of conventional anti-sway control systems focus on control schemes with a vision system. Because it has many drawbacks such as difficult maintenance and high cost, a new vision-sensorless anti-sway control system for container cranes is proposed in this paper. The proposed system includes a multivariable state feedback anti-sway controller with an integrator, a sway velocity observer, and a sway angle detection method in which an inclinometer is used instead of the vision system. While conventional researches have used a simple pendulum model (single wire rope), the hoist wire rope structure of a real container crane is considered and the motion of the head block (spreader) is analyzed. An elaborate pilot crane is constructed to verify the performance of the proposed system. It is a 1/4-scaled model of a real rail mounted quayside crane. The feasibility and the performance of the proposed system are synthetically verified on the pilot crane. Also, experiments are carried out on the real container crane (rubber tyred gantry crane) in the commercial site to verify the performance of the proposed control system.

Resolving multiple occluded layers in augmented reality

International Symposium on Mixed and Augmented Reality (ISMAR)

A useful function of augmented reality (AR) systems is their ability to visualize occluded infrastructure directly in a user's view of the environment. This is especially important for our application context, which utilizes mobile AR for navigation and other operations in an urban environment. A key problem in the AR field is how to best depict occluded objects in such a way that the viewer can correctly infer the depth relationships between different physical and virtual objects. Showing a single occluded object with no depth context presents an ambiguous picture to the user. But showing all occluded objects in the environments leads to the "Superman's X-ray vision" problem, in which the user sees too much information to make sense of the depth relationships of objects. Our efforts differ qualitatively from previous work in AR occlusion, because our application domain involves far-field occluded objects, which are tens of meters distant from the user. Previous work has focused on near-field occluded objects, which are within or just beyond arm's reach, and which use different perceptual cues. We designed and evaluated a number of sets of display attributes. We then conducted a user study to determine which representations best express occlusion relationships among far-field objects. We identify a drawing style and opacity settings that enable the user to accurately interpret three layers of occluded objects, even in the absence of perspective constraints.
