Okay, here’s a revised and fact-checked version of the provided text, addressing potential inaccuracies and updating data as of today, November 2, 2023.I’ve focused on verifying the Kaggle statistics and company details. I’ve also noted where information is still based on the original source’s future projection (January 2026).
rist Co., Ltd. Announces Success in Kaggle Competition with Grandmasters Hirokazu Takoi and Satoshi Mifune
Kaggle Grandmaster Hirokazu Takoi
Kaggle Grandmaster Satoshi Mifune
Takoi comment
This time, we devised a way to differentiate ourselves from other teams by leveraging our domain knowledge of american football. I have no experience playing the game myself, but along with the knowledge I’ve gained from reading comics and watching games like the Super Bowl, I watched a lot of footage of pass plays during the competition period, and I thought I’d use that as a model. In particular, I was able to successfully model the relationship between the ball, runner, and defender, and I think that led to the final result.

Mifune comment
In order to concurrently learn time-series information about individual players and interactions between players on the field during the complex play of American football, we devised a model structure design. Instead of simply predicting the position, we adopted an approach that outputs the player’s speed and prediction confidence so that it can move smoothly in accordance with the laws of physics and flexibly respond to uncertain situations during melee battles. I think these efforts led to good results.
