In many decision problems, there are two levels of choice: The first one is strategic and the second is tactical. We formalize the difference between both and discuss the relevance of the bandit literature for strategic decisions and test the quality of different bandit algorithms in real world examples such as board games and card games. For exploration-exploitation algorithm, we evaluate the Upper...
Nowadays people's life become more rich and convenient than before, but the obesity also become a problem with people. One cause of obesity is lack of exercise. Although the reason is known by people and the method of keeping health is self maintenance, but it is hard for most people, especially the elderly people. Because of this, we design a daily exercise support application, which is based on...
Knowledge on the social web presupposes to gather information about its current and potential users and document their relationships, interests and needs. A recent branch of sociology, the Actor-Network Theory or ANT, states that relations among human and nonhuman actors are equally important to comprehend social phenomena. Since scientists are potential users of huge computational support, their...
We propose a method to judge a walker's intention around pedestrian lights by using fuzzy rules. We detect pedestrian object in a movie of crosswalk area by using the code book method and acquire contour information. To improve the processing speed in this stage, we use parallel processing technique based on CUDA (Compute Unified Device Architecture). Now, we remove shadow which causes shape distortion...
In the aftermath of several recent catastrophic intelligence failures, the U.S. Government commissioned a series of studies to evaluate analytic methods and tradecraft. Those reports made specific recommendations to address consistent and systematic errors known as judgment biases found in all forms of analysis: predictive, estimative, and forensic. To correct for bias, a small number of methodological...
In this paper we describe a phonetic classification of Japanese puns (dajare). Basing on real life examples gathered from available sources (books, Internet), we divided Japanese puns into 12 groups with numerous subgroups, according to phonetic changes that occur within them. This classification was prepared for the NLP purpose, i.e. to be used in humor processing. Its usefulness was shown in a research...
Emotion estimation from sentences is helpful in semantic analysis and human-computer interaction. People sometimes express their emotions directly and sometimes describe experiences that produce various emotions. Emotion estimation requires both verbal expressions. We believe Japanese onomatopoeias could serve as a landmark of emotions. In this study, multiple raters judged emotions found in 324 onomatopoeias...
As human interfaces enhanced by augmented reality (AR) and ubiquitous service environments begin to take hold in society, researches are undertaken on daily life support services that focus on the availability of life logs. This paper presents an intelligent mirror (IM) system that is intended to assist the user with fashion coordination based on his/her clothes life logs. A clothes life log used...
In this paper, we built a behavior model for the Ubiquitous Display (UD) to provide a situation oriented service to the users in a large-scale public facility. The UD is a mobile-projection robot to support the user with visual information. If the UD provides a service in a public facility, we should assume the possible situations previously. According to the situation, the model should be built in...
Through this project, successful applicants from Korea and China will be accepted into the Graduate School of Engineering Master's Course, that was established in April 2011, at Nagasaki University. They will be trained to become highly skilled professionals with practical knowledge who can contribute to solving water environment conservation issues, including sustainable water use, in East Asia.
Web based machine translation is now public ally available to Internet users. To address its effectiveness in assisting people in real translation task, this paper presents a controlled user study on how human choose and modify MT results during translating the paper titles. It reveals the translation quality of MT system in certain aspects through an analysis of the translator log.
With rapid development of information and communication technology, human behavior has extended to mobile internet. In this paper, we studied posting behavior of micro-blog users in mobile internet. Statistical results suggest that there exist significant negative correlation between inter-event time and social concern. This means that users' interest in posting micro-blogs is influenced by social...
In order to keep the awareness of the problem without fading the experience of past disaster, it is effective to reexperience it with high presence sensation. in this study, earthquake disaster experience system that records the scene of the disaster and represents it with high presence sensation was developed. in this method, the scene of the real world is recorded using virtual sphere model and...
Although recent studies show that both topological structures and human dynamics can strongly affect information spreading on social networks, the complicated interplay of the two significant factors has not yet been clearly described. In this work, we find a strong pair wise interaction based on analyzing the weighted network generated by the short message communication dataset within a Chinese tele-communication...
Occupancy determination of a large room, such as university campus room, using pyroelectric infrared (PIR) sensors is difficult because PIR sensors are inherently insensitive to humans that are motionless and it is difficult to achieve 100% coverage even with multiple sensors. To overcome these problems, the authors propose using particle filtering of networked multiple PIR sensor data to improve...
The recent advances made in high throughput genomic sequencing allow researchers to accurately determine the genetic make-up of an individual. Sharing this data across research institutes has proven to be challenging as the amount of data and available bandwidth cause large delays. Here, we present a network of dynamic lightpaths dedicated to the life sciences which connects research groups within...
Functional modeling has been widely researched in the past decades and is considered to be effective in assisting concept design. However, construction of substantial design repository with abundant knowledge maintenance is still a problem. in this paper, we propose a model and approach for retrieve functional knowledge from existing products. First, we propose the functional knowledge retrieval model...
Chair comfort is an important design element of the modern life. in this study, a method based on the signal of posture transform was discussed to predicting subjective perceptions of long-term chair comfort. the signal of sEMG in the procedure of mutual transformation during six representative posture was recorded, then analysis of correlation between the change of subject comfort and the index of...
Along with the development of Internet technology, more and more design need to engage with the human elements. in this paper we first focus on the characteristics of Internet product and user requirement, then on this basis of user research, we build up a humanized system of Internet product design and a specific design method, at last we introduce the concept of emotional design and emphasize the...
With the advance of natural user interface technology, studies on detecting human movement and gestures have been conducted. Among these studies, sleep recognition is significant for energy saving as human's special behavior. This paper proposes a novel approach using a depth sensor and camera for increasing sleep recognition accuracy. Several potential errors of sensing gestures when sleeping are...
