🚨 New paper accepted to #ACL2025! We propose SudoLM, a framework that lets LLMs learn access control over parametric knowledge. Rather than blocking everyone from sensitive knowledge, SudoLM grants access to authorized users only. Paper: arxiv.org/abs/2410.14676… 🧵[1/6]👇
😴 Extending modality based on an LLM has been a common practice when we are talking about multimodal LLMs. ❓ Can it generalize to omni-modality? We study the effects of extending modality and ask three questions: arxiv.org/abs/2506.01872 #LLM #MLLM #OmniModality
Can LLM guardrails think twice before deciding? ✨ Check out our #ACL2025 paper: THINKGUARD — a critique-augmented safety guardrail! ✅ Structured critiques ✅ Interpretable decisions ✅ Robust against adversarial prompts 📑 arxiv.org/abs/2502.13458 🧵[1/n]
🚨 DPO works well on LLMs, but what happens when we apply it to VLMs/MLLMs? 🚀 Excited to introduce our #EMNLP2024 work on DPO for Multimodal LLMs! We identify the unconditional preference issues (where the model 𝐨𝐯𝐞𝐫𝐥𝐨𝐨𝐤𝐬 𝐯𝐢𝐬𝐮𝐚𝐥 𝐜𝐨𝐧𝐭𝐞𝐱𝐭), leading to severe…
🌟 Excited to present our #EMNLP2024 work: Monotonic Paraphrasing (MonoPara), a new approach to prompt optimization that enhances LLM generalization and robustness! 🌟
🚨Vision-Language Models (VLMs) are truly amazing. Ever wonder if their visual and textual "brains" always agree? I am excited to share our latest paper, where we tackle a critical challenge in VLMs, dubbed the 𝐜𝐫𝐨𝐬𝐬-𝐦𝐨𝐝𝐚𝐥𝐢𝐭𝐲 𝐩𝐚𝐫𝐚𝐦𝐞𝐭𝐫𝐢𝐜 𝐤𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞…
