Successfully deploying these models often requires both task-specific customization and rigorous auditing of their behavior. In this talk, I will begin by introducing a customization method called <i>Prefix-Tuning</i>, which adapts language models by updating only 0.1% of their parameters. Next, I will address the need for robust auditing by presenting a Frank-Wolfe-inspired algorithm for red-teaming language models, which provides a principled framework for discovering diverse failure modes. Finally, I will rethink the root cause of these control challenges, and propose a new generative model for text, called <i>Diffusion-LM</i>, which is controllable by design. </div><div><br></div><div><b>Bio: </b>Xiang Lisa Li is a PhD candidate at Stanford University, where she is advised by Percy Liang and Tatsunori Hashimoto. Her research focuses on developing methods to make language models more capable and controllable. Lisa is supported by the Two Sigma PhD fellowship and Stanford Graduate Fellowship and is the recipient of an EMNLP Best Paper award.</div><div><br></div><div><b><br></b></div><div><b><img id="<A0C6ED97-9439-473D-9421-43DA5BB02586>" src="cid:19DE68E6-AEA0-4DA8-A0EC-267EC3D1AF77" alt="Image 1.jpeg" class="Apple-web-attachment Singleton" style="opacity: 1;"><br></b></div><div><div><b><br></b></div><div><b>Host: Haifeng Xu</b></div><div><b><br></b></div><div><b>---</b></div></div><div>
