MeVer participation in Deepfake detection challenge
It has been almost 2 months since the final deadline for the challenge on the Kaggle platform. Competition organizers have just finalized the standings (13th of June 2020) in the private leaderboard. A Kaggle staff member mentioned in a discussion that competition organizers took their time to validate winning submissions and ensure that they comply with the competition rules. This process resulted in the disqualification of the top-performing team due to the usage of external data without proper license. This caused a lot of disturbance among the Kaggle community mainly because the competition rules were vague.
MeVer meets DeepTrace
Polychronis from the MeVer team had the opportunity to visit DeepTrace Labs, a company based in Amsterdam, focusing on deepfake detection. MeVer and DeepTrace have recently started collaborating on the problem of DeepFake detection, which MeVer faces in the context of the WeVerify project. As part of this collaboration, the two teams also joined forces to tackle the Kaggle’s DeepFake Detection Challenge. The goal of the challenge is to build effective solutions that can help detect DeepFakes and manipulated media. The final deadline for submissions is March 31, 2020.
