The Rakuten-Viki Global TV Recommender Challenge has finally come to a successful closure on the 16 September 2015. Six Teams (Team Merlion, Team GM, Team Haipt, Team Pritish,Team Gbenedek & Team Lenguyenthedat) were invited to present publicly in front of a pool of audiences and the judges. Rakuten was generous enough to make the presentation opened to public for the first time ever in DEXTRA history. We were also honored to have Mr Kiren Kumar, Director, Infocomms & Media Singapore Economic Development Board to give a welcoming speech on that evening.
After a long deliberation, the judges’ votes were unanimous, they voted that Team Merlion (Duan Rubing, Liu Yong, Yang Xulei, Rick Goh, Hu Nan, Tan Yong Kiam, Wu Zhen Zhou, Yang Feng) were the winners for the challenge. Winning team Merlion employed an elegant algorithm that performs outstandingly in both public and private leaderboards, identified and engineered very useful features, as well as discovered and visualised some key insights from the data provided.
