Two Toshiba Researchers Achieve the Rank of “Kaggle Competition Grandmaster”
-Recognition of continuous excellent results on the world’s largest AI competition platform-

Kawasaki, Japan–Two researchers at Toshiba Corporation, Yasuhiro Ohkawa and Tomoki Uchiyama, have been certified as “Kaggle Competition Grandmasters” in Kaggle *1, the largest- competition platform in the field of AI worldwide. Kaggle Competition Grandmaster is the highest title given to individuals who consistently obtain superior results in the Kaggle Competition. To date, this title has been awarded to only 395 out of roughly 200,000 participants, representing the extremely limited top tier of competitors *2. Ohkawa and Uchiyama participated in the Kaggle Competition individually, focusing mainly on the fields of image recognition and image analysis, and have continually achieved high rankings. Both were recognized as Kaggle Competition Grandmasters after receiving their fifth gold medal each. Furthermore, Ohkawa ranked 11th (highest ranking 9th) and Uchiyama ranked 8th in the overall Kaggle Competition standings from among the roughly 200,000 participants *3.
