주로 연구하는 분야는 데이터 사이언스, 강화학습, 딥러닝 입니다.
크롤링과 텍스트마이닝은 현재는 취미로 하고있습니다 :)
크롤링을 이용해서 인기있는 커뮤니티 글만 수집해서 보여주는 마롱이라는 앱을 개발하였고
전국의 맛집리스트와 블로그를 수집해서 맛집 추천 앱도 만들었었죠 :) (시원하게 말아먹..)
지금은 인공지능을 연구하는 박사과정생입니다.

いろいろな練習を進めるというメリットがあります。そのような面にもかかわらず問題があります。説明をするときに具体的に表現をせずに"これが、それが、これをこう"代名詞をたくさん書いて表現します。したがって、画面上のマウスポインタを一生懸命見ながら、どのような操作とアクションをとるかを詳しく見ていく必要があります。 明らかに存在する名称と技法などを共有して説明するという感じではなく、自分がすることを実演するのを録画して見せてくれる感じです。これは、今後新しい講座を作成する場合は、必ず改善すべき部分と考えられます。このため、受講生の立場で疲労度が上昇し、内容的に整理が難しいという点があります。
