Abstract

大语言模型（LLM）与视觉语言模型（VLM）已在众多任务中展现出卓越性能。然而，随着其应用日益广泛，这些模型在忠实性、安全性和可解释性方面的根本局限性逐渐暴露。本次报告，Vidal教授将提出一个统一视角，探讨如何通过原则性模型干预与可解释决策框架应对这些挑战。Vidal教授首先将介绍简约概念工程（PaCE），该方法通过选择性消除模型内部不良激活来提升忠实度与对齐性，在保留语言能力的同时有效缓解幻觉与偏见表述问题。随后，将阐述信息追踪（IP）框架——一种基于可解释设计理念的预测系统，通过一系列用户可理解的信息化查询取代不透明的推理过程，在保持预测准确性的同时生成简洁解释。在文本、视觉及医疗领域的实验结果表明，这些方法能在不牺牲性能的前提下显著提升系统透明度，研究成果共同为构建兼具强大能力、忠实性与人类价值对齐的人工智能系统指明重要方向。

Large Language Models (LLMs) and Vision Language Models (VLMs) have achieved remarkable performance across a wide range of tasks. However, their growing deployment has exposed fundamental limitations in faithfulness, safety, and transparency. In this talk, Prof. Vidal will present a unified perspective on addressing these challenges through principled model interventions and interpretable decision-making frameworks. He first introduces Parsimonious Concept Engineering (PaCE), an approach that improves faithfulness and alignment by selectively removing undesirable internal activations, mitigating hallucinations and biased language while preserving linguistic competence. Prof. Vidal then present Information Pursuit (IP), an interpretable-by-design prediction framework that replaces opaque reasoning with a sequence of informative, user-interpretable queries, yielding concise explanations alongside accurate predictions. Results across text, vision, and medical tasks illustrate how these ideas advance transparency without sacrificing performance. Together, these contributions point toward a broader direction for building AI systems that are powerful, faithful, and aligned with human values.
