A classified dataset of about 40,000 photos is proposed, composed of both faces and objects, where it is possible to find examples of copy-move, splicing, and deepfake manipulations. For the FaceForensics dataset which was generated with Face2Face technique, and also inherently having larger variance between real and fake classes' images. The best model, developed by Selim . The governance of the challenge will be facilitated and overseen by the Partnership on AI's new Steering . For the purposes of this project, recall is an important metric as we’d rather have a false positive than a false negative. The accuracy of this model is much better than the baseline CNN as it has now cracked 90% with an almost equal recall. Found inside – Page 130The modified face images contain different types of artifacts and features. ... Also, the number of different subjects for the deep fake dataset is ... With little to no effort, people can easily learn how to generate deepfake videos with only a few victims or target images. Found inside – Page 192Using artificial images and algorithms, a Deepfake can be generated by almost anyone. ... It basically produces and image based upon the dataset. The CNN using a pretrained convolutional base was much more accurate, but only after retraining the pretrained convulational base. After analysing and modeling the data, we have come to the following results: Based on this analysis, we can offer the following recommendations: With more time, we can improve this project in the following ways: Please review the narrative of our analysis in our jupyter notebook or review our presentation, A mildly sarcastic, often enthusiastic Data Scientist based in central Florida. 1 University at Albany, State University of New York, USA Here, we used two small neuron Conv2D layers that are fed into a single Dense output layer. for . For all the models we extracted the output of the last layer before classification to see if the vectors are representative of the images. The DFDC dataset comprises a whopping 25 TB of raw footage, making it the largest publicly available deepfake dataset. Place all the saved models in the folder called models.
