Study on the social divide using a reinforcement learning MAS model

ITO Nao, MAEDA Yoshinobu

IEICE technical report 107 ( 368 ) 73 - 76 2007.11

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In recent years, a "social divide" such as income and professim divides, has noticed as one kind of social issue. It is defined that, in the divided groups, the member belonged to one group cannot move on any other groups. Such fixation of social careers causes non-activation of ecomomy. In this study, we suggested the dynamic economic model described by a multi agent system, and tried to understand mechanisms how the social divide emerges in the model. Particularly we discussed how achieved a good balance between fairness and efficiency in the model.

Participation-type agent-based simulation of group formation and minority exclusion

MAEDA Yoshinobu, NAGASAWA Miwako

IEICE technical report 107 ( 273 ) 7 - 12 2007.10

Language：English Publisher：The Institute of Electronics, Information and Communication Engineers

Bullying is one of social problems and we have to solve this problem for happiness and well-being of the individuals. It is very important for junior high school students that, to make friends, they find conunon sense of values, such as similar interests, same hobbies, and some kind of common activity or striving. However, a few students who cannot find the common sense of values are capable to be the minority, or the potential victim of the bullying. To describe such phenomena, we proposed the formalized agent-based model of both the group formation and minority exclusion to clarify the appearance of the minority. Secondly, in order to model real organizations and social phenomena as hybrid multi-agent systems consisting of both human and machine agents, we upgraded the model to a participation type, so-called, multi-agent system model with making the gaming simulation possible. Thus, an actual player could interact the machine agent, or agent, who worked by the stochastic rules of the model. We examined the availability in both university students and a junior high school student, and obtained similar results so as to be shown by the formalized agent-based model.

Behavior of a coupled system of circuit models reproducing action potentials

HAYAKAWA Akinori, MAEDA Yoshinobu

IEICE technical report 106 ( 413 ) 7 - 10 2006.12

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

A coupled system of nonlinear differential equation models that reproduce action potential form shows chaotic complex behaviors and acceleration phenomena. In this report, we investigated behaviors of electronic circuit models reproducing action potentials, proposed by Maeda et al. The electronic circuit model is effective in discussing relation between simultaneously dynamics and power consumption (or energy consumption), whereas the differential equation model contributes to the analysis of dynamics. When the coupled resistance is relatively small, a coupled system of this electronic circuit model shows acceleration phenomena with low power consumption, and, as such, shows that the synchronized period is small and the power consumption is reduced in the coupled system. Conversely, when the coupled resistance becomes large, the synchronization collapses and progressive wave is observed. We investigated the generation of the progressive wave in relation to the peristaltic motion, from the viewpoint of the power consumption.

Group formation dynamics in the interaction of agent model

OHTAKI Makiko, MAEDA Yoshinobu

IEICE technical report 106 ( 413 ) 11 - 16 2006.12

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

School bullying is one of the most important problem we must solve, but we have never found clues of solution. This study examines a school bullying by MAS (Multi-Agent System) method, based on an assumption that the bullying emerges from perspective of student-student interaction [9]. In the report, we presented two improved models based on the original model [9], "Teacher-agent added model" and "Substituted conformity model". Then, by simulating these models, we proposed to understand group formation dynamics and the bullying structure.

Route Selection Software for the Visually Impaired using Relative Position Measurement Approach

KOUMO Yutaro, MIYAJI Takaaki, MAEDA Yoshinobu, MIYAKAWA Michio

IEICE technical report 106 ( 408 ) 17 - 22 2006.11

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

We have developed the AHP-GIS-based travel assist system for the visually impaired of especially the 40% who are almost staying home (Hikikomori). The Hikikomori visually impaired people have low self-efficacy on travel because their guide helpers in traveling lead them to the destination safely. Then, it is few for the Hikikomori visually impaired to have opportunity of self-determination on travel. The visually impaired should decide, or advise equally the guide helper, when determining the travel route. This system developed tends to assist the self-determination of the Hikikomori visually impaired. In this report, we suggest that, in the AHP or the decision-making process of the system, a relative position measurement approach should be available in comparison with the other approaches.

Fluorescent light communication: a study of waveform characteristics and decoding methods

KOBAYASHI Suguru, MAKINO Hideo, LIU Xiaohan, KUDO Jumpei, MAEDA Yoshinobu

2006 ( 116 ) 101 - 108 2006.11

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

Indoor pedestrian navigation systems using a location based service will be as useful as the better known 'GPS' outdoor systems. We have been studying a position based system using fluorescent light communication. In this paper we describe how to extract location signals from fluorescent light using digital signal processing. The first step is to calculate the optimal sampling frequency for the signal processing. This is followed by an analysis of the characteristics of the received waveform from the fluorescent light. Based on the analyses of the waveform characteristics we used a decoding method with a sampling frequency of 2MHz at the 1.5m distance between a photo sensor and the fluorescent. Our experiments confirmed the suitability of the method and the error rate of each decoded bit was less than 10^<-4> in all combinations of 8 bit length transmission signal patterns.

Development of an Indoor-outdoor Information Input Program as a Pedestrian Location Guidance System

TAKAMI Ryo, MAKINO Hideo, MAEDA Yoshinobu

2006 ( 116 ) 109 - 116 2006.11

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

A pedestrian location guidance system will make it possible to guide a person using GPS position information, using visible light communication or RFID. To prepare guidance data for the system, we have developed an indoor-outdoor information input program. The program uses GIS data as the outdoor layer and CAD (Computer Aided Design) data as the indoor layer to delimit the data area. However, there are many kinds of CAD data formats; so we handled them as bitmaps, and used image processing to improve the accuracy of the indoor information database. Experimentally, we confirmed an improvement of the accuracy of the indoor information database.

Development of an Indoor-outdoor Speech Input Program as an Universal Location Guidance System

TAKAMI Ryo, MAKINO Hideo, MAEDA Yoshinobu

IEICE technical report. ME and bio cybernetics 105 ( 304 ) 31 - 34 2005.9

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

An universal location guidance system will make it possible to guide a person using (GIS/GPS) position information, coupled through a visible light communication method or RFID. To prepare guidance data for the system, we have developed an indoor-outdoor speech input program. The program uses GIS data as the outside, or external layer and CAD data as the indoor or internal layer to localize the data area. Experimentally, the first step is to create the information database. The first component of the data base is the specification of the guidance information data at each layer and then the input of the speech information data. Secondly, we confirmed that we could receive speech guidance to each position.

MIYAJI Takaaki, MAEDA Yoshinobu, MAKINO Hideo

IEICE technical report. Welfare Information technology 105 ( 186 ) 15 - 20 2005.7

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

To encourage a travel of the negative blind persons for going out, so-called Hikikomori, we have developed the AHP(Analytic Hierarchy Process)-GIS(Geographic Information System)-based travel assistive system for the visually impaired. In this system the users can select a travel route from several available routes reflecting their favorite. We would like to promote their self-efficacies for travel using this sort of decision-making opportunity, presented by our AHP-GIS system. In this report, the factor analysis was introduced to a road database of the AHP-GIS system to find the above available routes. Eventually we showed the validity of this method in the Bandai district of Niigata city.

Multi-agent simulation on a school bullying emerged from the mobbed group

ANEZAKI Kazuya, MAEDA Yoshinobu, MAKINO Hideo

IEICE technical report. Welfare Information technology 105 ( 186 ) 61 - 66 2005.7

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

A school bullying is a serious problem in the world. In order to vanish the school bullying, it is necessary to consider it from various fields such as the school counseling, the psychological sociology and the mathematical engineering. We set the mobbed classroom model (multi-agent system) in the personal computer to consider the bullying problem from the viewpoint of the mathematical engineering. In our model, every agent (students) has the several value formulated and interacts randomly with the other agents. Although our model was simple, the agents found a unique agent out as a heterogeneous person. In this report, we report that if the agent interacts, not randomly but friendly, the bullying problem can be reduced.
