Supervised Contrastive Learning for Generalizable and Explainable DeepFakes Detection

[Paper]
Ying Xu, Kiran Raja, Marius Pedersen

Introduction:

We propose a generalizable detection model that can detect novel and unknown/unseen DeepFakes using a supervised contrastive (SupCon) loss. We obtain the highest accuracy of 78.74% using proposed SupCon model and an accuracy of 83.99% with proposed fusion in a true open-set evaluation scenario where the test class is unknown at the training phase.

Framework:

How to use:

main_supcon.py
main_linear.py

Just remember two trains needed to be conducted.
