Excited to share our paper “When Are Concepts Erased from Diffusion Models?” at @NeurIPSConf! We introduce two conceptual models for erasure mechanisms in diffusion models, and a suite of probes to recover supposedly forgotten concepts. Project website: unerasing.baulab.info

In our #ICLR2025 paper, we introduce WIND 🌬️ A method that embeds a distortion watermark directly in the diffusion noise! Our method ensures that the watermark in one image does not reveal information about the watermark in other images 🤫 📝 arxiv.org/abs/2412.04653 (1/5)

My team with @Yuvlem won🥇first place in the defense track of the Capture The Flag-LLM Challenge at @satml_conf. In the competition, each team hides a secret in an LLM context, and other teams try to discover it. Here's how we used ideas from Judo and Cooking to do it👇 🧵1/11

The @satml_conf LLM CTF has come to an end! 🥇Huge congrats to the defender winning team Hestia (@NivCohenHuji @Yuvlem) whose top defense was broken only once, and the attacker winning team @WreckTheLine (@adragos_ @sijsu @FetchDEX @y011d4 @ca7ir) who broke all defenses!
