Pour les collègues francophones, vous saviez que le FID était tout cassé ? Moi non plus. Pourtant, si on s'y prend bien, on peut calculer le FID avec moins de 1000 images. J'en parlerai au GRETSI fin août : hal.science/hal-05142942 👀

Évaluation des générateurs d'images à partir de peu d'exemples : calculer le FID avec 10 fois moins d'images, c'est possible
La distance Inception de Fréchet (Fréchet Inception Distance ou FID) est une métrique standard pour l'évaluation des modèles génératifs images. Construite sur la distance de Wasserstein, le FID mesure...

🚗 Ever wondered if an AI model could learn to drive just by watching YouTube? 🎥👀 We trained a 1.2B parameter model on 1,800+ hours of raw driving videos. No labels. No maps. Just pure observation. And it works! 🤯 🧵👇 [1/10]

Airborne #LiDAR has revolutionized the study of ancient rainforest civilizations by seeing through dense canopies. Yet archaeologists still annotate their data manually. Introducing Archaeoscape at #NeurIPS2024 —the first deep learning-scale, open-access archaeological dataset🧵👇
