  • Taguchi, Chihiro; Sakai, Yusuke; Watanabe, Taro (Association for Computational Linguistics, 2021-06)
    We introduce a Cyrillic-to-Latin transliterator for the Tatar language based on subword-level language identification. The transliteration is a challenging task due to the following two reasons. First, because modern Tatar ...
  • Higashiyama, Shohei; Utiyama, Masao; Watanabe, Taro; Sumita, Eiichiro (Association for Computational Linguistics, 2021-06)
    Morphological analysis (MA) and lexical normalization (LN) are both important tasks for Japanese user-generated text (UGT). To evaluate and compare different MA/LN systems, we have constructed a publicly available Japanese ...

    Recently, cyberattacks on Controller Area Network (CAN) which is one of the automotive networks are becoming a severe problem. CAN is a protocol for communicating among Electronic Control Units (ECUs) and it is a de-facto ...
  • Harada, Koji; Arai, Ismail; Kashihara, Shigeru; Fujikawa, Kazutoshi (ACM, 2020-11)
    In search and rescue (SAR) operation, the potential of Unmanned Aerial Vehicles (UAVs) gathers great attention. Existing studies have made various experiments to find victims by a UAVs with a single sensor, e.g., one of ...
  • Chauque, Euclides; Arai, Ismail; Fujikawa, Kazutoshi (IEEE, 2020-12-16)
    Online applications adoption, and success are driven by a multitude of factors among them the service response time. This is natural as users tend to prefer a faster service than a slower. However, it is challenging to ...
  • Kibrom Desta, Araya; Ohira, Shuji; Arai, Ismail; Fujikawa, Kazutoshi (2020-11-27)
    CAN uses no authentication and encryption mechanisms for secure communication. To solve the security issues of the CAN bus, a deep learning-based intrusion detection systems have been proposed. But due to the high dimensional ...
  • Zhou, Hangyu; Fujimoto, Yuichiro; Kanbara, Masayuki; Kato, Hirokazu (ACM, 2020-10)
    In this paper, factors with positive effects in the playback of virtual reality (VR) presentation in training are discussed. To date, the effectiveness of VR public speaking training in both anxiety reduction and skills ...
  • Alessandro, Luchetti; Edoardo, Parolin; Isidro, Butaslac; Fujimoto, Yuichiro; Kanbara, Masayuki; Paolo, Bosetti; Mariolino, De Cecco; Kato, Hirokazu (IEEE, 2020-12-16)
    The purpose of this study is to analyze the different kinds of ex- proprioceptive visual cues on an Augmented Reality (AR) system during gait exercise, on top of understanding which cues provide the best visualizations in ...
  • Tainaka, Keishi; Fujimoto, Yuichiro; Kanbara, Masayuki; Kato, Hirokazu; Moteki, Atsunori; Kuraki, Kensuke; Osamura, Kazuki; Yoshitake, Toshiyuki; Fukuoka, Toshiyuki (IEEE, 2020-11-13)
    Augmented reality (AR) systems support complex tasks like assembly by overlaying task-related content onto the real world. In recent years, the effort of designing and developing assembly task support systems in AR decreased ...
  • Butaslac, Isidro III; Luchetti, Alessandro; Parolin, Edoardo; Fujimoto, Yuichiro; Kanbara, Masayuki; De Cecco, Mariolino; Kato, Hirokazu (Springer, Cham, 2020-08-31)
    The aim of this work is to facilitate the application of Augmented Reality (AR) in rehabilitative clinics to support the therapist by providing real-time AR visualizations. The feasibility of AR as a support tool in ...
  • Arai, Ismail; Kametani, Masahiro; Honda, Norihiko; Akiyama, Toyokazu (IEEE, 2020-10-13)
    With the spreading of digital tachographs for transportation systems, IoT is coming to route bus fields as well. The primary purpose is to make an operation of route buses efficient by glancing over the status of the bus ...
  • Inoue, Naoki; Fujimoto, Yuichiro; Plopski, Alexander; Okahashi, Sayaka; Kanbara, Masayuki; Hsu, Hsiu-Yun; Kuo, Li-Chieh; Su, Fong-Chin; Kato, Hirokazu (Springer, Cham, 2020-07-10)
    The motor control of individual fingers is an important part of daily life, but there are many people who have difficulty with it, such as elderly people and stroke patients. While continuous rehabilitation is necessary ...
  • Ohira, Shuji; Araya, Kibrom Desta; Kitagawa, Tomoya; Fujikawa, Kazutoshi; Arai, Ismail (IEEE, 2020-07-17)
    Controller Area Network (CAN) is one of the in-vehicle network protocols that is used to communicate among Electronic Control Units (ECUs) and has been de-facto standard. CAN is simple and has several vulnerabilities such ...
  • Rach, Niklas; Matsuda, Yuki; Yasumoto, Keiichi; Minker, Wolfgang (European Language Resources Association, 2020-05)
    We present an approach to evaluate argument search techniques in view of their use in argumentative dialogue systems by assessing quality aspects of the retrieved arguments. To this end, we introduce a dialogue system that ...
  • Kubo, Hiroyuki; Tokoi, Kohe; Mukaigawa, Yasuhiro (Association for Computing Machinery, 2015-07)
