    We propose an interactive image editing system that has a confirmation dialogue strategy using an entropy-based uncertainty calculation on its generated images with Deep Convolutional Generative Adversarial Networks (DCGAN). ...
  • Tanaka, Hiroki; Iwasaka, Hidemi; Matsuda, Yasuhiro; Okazaki, Kosuke; Nakamura, Satoshi (IEEE, 2021-04-27)
    Goal: Although automated social skills training has been proposed to enhance human social skills, the following two aspects have not been adequately explored: what types of feedback are effective from virtual agents and ...
  • Nakasai, Keitaro; Hata, Hideaki; Matsumoto, Kenichi (IEEE, 2018-10-22)
    Eclipse, an open source software project, acknowledges its donors by presenting donation badges. However, the effect of this strategy is unknown. We found that donation badges are appealing for donors and organizers because ...
  • Okada, Joji; Ishio, Takashi; Sakata, Yuji; Inoue, Katsuro (情報処理学会, 2018-06-15)
    レガシーなメインフレームシステムには,拡張子が存在せずプログラミング言語が不明なソースコードファイルが多数存在する.レガシーシステムを分析する際には各ソースコードファイルのプログラミング言語を判定する必要があるが,これを手作業で行うと多大な労力が必要となってしまう.本研究ではプログラミング言語の判定作業を支援するために,手作業で判定すべきファイルの代表をクラスタリングによって選出する手法を提案する.正確な判定を支援するため,提案手法はパ ...
