This page introduces research projects going in our laboratory. You may join the project you are interested in, or you can start a new project based on thorough survey of literature.
The statement under the window “Stand on the shoulders of giants” comes from the statement mentioned by Isaac Newton: “If I have seen further it is by standing on ye sholders of Giants.” If you want to start a new project, there must be some papers that have common things. We should build our research work on the works of our predecessors.
Social Simulation Systems (SSS) have individual-level SSS, oranization-level SSS, government-level SSS, nation-level SSS, and world-level SSS. We can start to develop a small-level SSS, then try to develop a larger-level SSS. Otherwise we can develop a prototype SSS then develop a complicated SSS.
Social Simulation Systems: From Individual-Level SSS to World-Level SSS
World-level SSS tries to simulate an international network. Real-world-level SSS will have a number of agents who live in that world. Althogh we propose a prototype SSS, our goal is to develop real world trade among residents in the world.
Project on Market: Du Niso (2012-)
We develop an agent-based simulation model about signaling to avoid a market failure.
Project on Minority Game: Takuya Harada (2013-)
This project tries to find a phonomenon caused by a large number of agents in a minority game.
Nation-level SSS reveals effects of policies in a nation.
Project on Consumption Tax: Sho Sugiura (2014-)
This project tries to show a relationship between consumption tax increase and economic conditions.
Project on Pension System: Du Nisuo (2013-), Zhibin Chen (2007-2011), Daisuke Banjo (2005-2010)
This projects show a transition of pay-as-you-go pension system to generational pension system. We also try to show regional effects of pension systems.
Project on Policy Positions of Parties: Yusuke Chamoto (2005-2009)
This project shows transitions of political positions of parties based on voters political positions.
Govenment-level SSS examines policies in a local government or a region with several local communities.
Project on Airport Selection: Naoki Kasatani (2011-2013)
This project shows how to balance the number of travelers who uses several airports.
Project on Hospital Selection: Shintaro Tokura (2006-2010)
This project simulates medical institute selection of residents in a city.
Project on Voting Place Selection: Kenta Konishi (2007-2011)
This project proposes a multi-objective optimization approach to develop an optimized allocation of voting places to increase the voter turnout.
This level of SSS shows a mechanism of decision making of individuals.
Project on Facility Selection: Daichi Kotaka (2008-2010)
This project reveals a transition of facility selection based on the congestion of the facility. We develop a system based on behavioral economic data.
Project on Learning Agents: Takashi Nakamura (2002-2006), Yu Mizoguchi (2002-2006), Masatoshi Yamaguchi (2003-2007)
This project try to approach decision making process using neural networks, reinforcement learning and evolutionary computation.
Supporting Systems for SSS
Supporting systems for SSS includes systems of supporting parameter tuning of developed systems, parallell computing, distributed computing, and visual output processing.
Project on Large-Scale Computation: Takuya Harada (2013-), Yusuke Aoki (2006-2010), Yoshihisa Tanaka (2006-2010), Sen-ichi Morishita (2006-2010)
This project shows how to use a large-scale computing for social simulations with a large number of agents.
Project on Reconstruction of Attributes of Agents: Daiki Masui (2013-)
This project tries to reconstruct attributes of agents from statistics.
Project on Visualising SSS Outcomes: Goichi Morimoto (2008-2012)
This project shows a tool to visualize simulation outcomes using Google Earth.
Project on Natural Language Processing: Shoko Shirato (2002-2006)
This project tries to categorize documents written in natural language.
Project on Combinatorial Optimization Problems: Ryota Itai (2002-2006), Akinori Taki (2006-2010), Takuya Harada (2013-)
This project develops methods for combinatorial optimization prombels that frequently occur in social simulation problems.
