โœจ With CrossAtlas, we: ๐Ÿ–ฅ๏ธ Compare projections for XR-to-desktop collaboration ๐Ÿ‘ฅ Study 48 participants across three spatial layouts ๐Ÿ’ก Find equirectangular stays more robust as curvature increases

๐Ÿšจ New paper alert! ๐Ÿšจ Can you believe it? Flawed thinking helps reasoning models learn better! Injecting just a bit of flawed reasoning can collapse safety by 36% ๐Ÿ˜ฑ โ€” but we teach large reasoning models to fight back ๐Ÿ’ช๐Ÿ›ก๏ธ. Introducing RECAP ๐Ÿ”„: an RL post-training method that trains models to override unsafe reasoning, reroute to safe & helpful answers, and stay robust โ€” all without extra training cost. โœจ Safer reasoning ๐Ÿค– โœจ Stronger jailbreak resistance ๐Ÿ”“ โœจ Lower overrefusal ๐Ÿ™… โœจ Preserved core reasoning capability ๐Ÿง  #LLM #ReasoningModels #RLHF #AISafety #Alignment #MachineLearning

โ€œI did it to make my presentations look humorous. Nobody at MIT taught us DEI or respect.โ€ - Excuse given by MIT Media Lab researcher who has received many recognitions. NOTE: Most MIT Media Lab researchers I know are highly respectful and morally upright.
Mitigating racial bias from LLMs is a lot easier than removing it from humans! Canโ€™t believe this happened at the best AI conference @NeurIPSConf We have ethical reviews for authors, but missed it for invited speakers? ๐Ÿ˜ก

๐Ÿ˜Ž Our paper on the LLM safety landscape has been accepted at @NeurIPSConf 2024! #Safety #LLM #MachineLearning
LLM safety alignment can be easily compromised by finetuning with only a few adversarially designed training examples. ๐Ÿ˜ฒ Why? Are all open-source LLMs equally vulnerable to finetuning? How fast does the model start to break during finetuning? ๐Ÿค”
