* What is a machine learning competition?

This is a machine learning development method that is attracting attention in recent years. It involves publishing specific challenges and related data and calls on the wider public to develop models to solve them, in order to develop models with higher accuracy and apply them to actual systems.

New talent with outstanding ideas and technologies will be discovered in this kind of competition, and it offers opportunities to participate in the government's system development projects. By doing so, it is also expected to promote efficient innovation and system development.

The AI x Trademark: Image Search Competition is about teaching machines using data from similar figurative trademarks to develop models that predict similar images out of numerous existing figurative trademarks and comparing the accuracy of the results. Submitted models will be screened, and winners will be awarded.

The opening ceremony will be live streamed on YouTube on the competition's start date (November 26, 2021 [Fri.]).
