  • Analyzing an influence of collecting broken robots in large-scale structure assembly though a cooperation among multiple robots, Masayuki Otani, Hiroyuki Sato, Kiyohiko Hattori, Keiki Takadama, IEEJ Transactions on Electronics, Information and Systems, IEEJ Transactions on Electronics, Information and Systems, 133(9), 12 - 1737, 2013 , Refereed
    Summary:This paper focuses on the distributed control of the multiple robots which may be broken and investigates how the robots complete their task by collecting broken robots through the simulation of the large-scale structure assembly. For this purpose, we conduct multiagent simulation for collecting broken robots under the different failure rate of robots. Through the intensive simulations, we have revealed that a collection of broken robots before completing their own task (i.e., deploying their panel) is more effective than after complete their own task. ©2013 The Institute of Electrical Engineers of Japan.
  • Recommender System for Clarifying User's Preference by Showing Other Categories' Items, Keiki Takadama, Fumiaki Sato, Masayuki Otani, Kiyohiko Hattori, Hiroyuki Sato, Tomohiro Yamaguchi, Transactions of the Japanese Society for Artificial Intelligence, Transactions of the Japanese Society for Artificial Intelligence, 28(2), 210 - 219, 2013 , Refereed
    Summary:The paper proposes a novel recommender system which supports users to clarify the most appropriate preference by recommending other categories' items that almost meet the attributes selected by users. Such an advantage is achieved by both the preference concretization of users and the preference change of users. To investigate the effectiveness of the proposed system, we conducted the human-subject experiments and found that the proposed system supports users to find their desirable items by clarifying their preference. Concretely, the following implications have been revealed: (1) the proposed recommender system with both the serendipity and decision buttons enables users to clarify their preference by comparing items which are classified in different categories (2) in detail, the item recommendation based on the selected item attributes contributes to clarifying the users' preference through a change of their preference, while the item recommendation based on the item characteristic contributes to clarifying the users' preference through a concretization of their preference and (3) the proposed recommender system with the decision button succeeds the further clarification of the preference of users who have already clarified it. keywords: recommender system, awareness, decision support, human-agent interaction, preference clarification, category. © 2013, The Japanese Society for Artificial Intelligence.

    Summary:This paper focuses on the distributed control of multiple robots that may be broken and investigates recovery capability, which means how robots can complete assembly, when some are broken, through the assembly of a different-scale solar-powered satellite. We thus conduct simulation at different failure rates of robots that use our proposed deadlock avoidance. Through intensive simulation, we show that (1) our proposed method with no information sharing keeps high recovery capability and (2) this method is robust against differences in structure scale.
  • Robustness to bit inversion in registers and acceleration of program evolution in on-board computer, Tomohiro Harada, Masayuki Otani, Yoshihiro Ichikawa, Kiyohiko Hattori, Hiroyuki Sato, Keiki Takadama, Journal of Advanced Computational Intelligence and Intelligent Informatics, Journal of Advanced Computational Intelligence and Intelligent Informatics, 15(8), 1175 - 1185, 2011 , Refereed
    Summary:This paper focuses on an on-board computer (OBC) that evolves computer programs through bit inversion and targets analyzing robustness against bit inversion in registers. We also propose a new method that can change the number of computer programs dynamically. Intensive experiments revealed the following: (1) Correct programs can be maintained even in bit inversion in registers in addition to bit inversion in instructions. (2) Our proposal accelerates program evolution by increasing the population size, i.e., the number of programs, within fixed memory size.
