The content of the competition was to detect the playerer helmet collision from a recorded video of American football. It was necessary to learn video data, annotation data for helmet rectangles, player tracking data, etc., and output the coordinates of the frame where the collision occurred and the target helmet.
Hirai achieve high accuracy by separating the detection of the helmet and the judgment of the collision as separate tasks and inferencing them multiple frames before and after the collision when making the judgment of the collision. He was able to win a Gold medal in this task. He also finished sixth among 459 teams from all over the world, despite his solo participation.

Hirai’s comment: “Work experience such as AI development for detecting humans and objects of robots and creation of AI models for video data led to this Gold medal award.

Global Walkers will continue to actively encourage participation in various competitions with the aim of improving the skills of young AI engineers. In addition, we will use these experiences to propose to client companies and solve problems.
* What is “Kaggle”?
Kaggle is a predictive modeling and analysis method-related platform where companies and researchers post data and statisticians and data analysts around the world compete for the optimal model. Competitions for various issues have been held since 2010, and we use machine learning to analyze / model issues that include actual data provided by companies, etc., and compete for prediction accuracy. Kaggle can participate in these competitions for free via the internet. Since it is free of charge, researchers and engineers from all over the world participate in the study of technology.
