Happy to share that our paper “ARIA: Adversarially Robust Image Attribution for Content Provenance” (arxiv.org/abs/2202.12860) is published at the #CVPR2022 Workshop on Media Forensics 🕵️ So why does adversarially robust content provenance matter? A paper thread below! 🧵1/n

Fake news and misinformation are major societal problems that we're excited to address through our image and video provenance AI research – at @cvssp_research and with Adobe and the Content Authenticity Initiative (CAI). Details in-thread for our 2021 papers at ICCV, CVPR, CVMP

Maybe I should just do a recap of all the awesome @streamlit Drawable Canvas apps for its first anniversary 🙂 "Compositional Sketch Search" - an algorithm for searching image collections using free-hand sketches 😳 App: share.streamlit.io/alexblck/… by @AlexBlackAI

Here is my new blog post on flow-based deep generative models. Different from GAN or VAE, these model explicitly learn the probability density function of the real data using normalizing flows. lilianweng.github.io/lil-log…
