EviDex: Chasing the Truth Before It Expires

In this episode of AI on the Hill in the Spotlight, host Vivian sits down with Shuang Cao, an AI researcher, to take a closer look at EviDex — a project focused on making sure AI systems give fresh, accurate answers instead of relying on outdated information. Shuang's work centers on building reliable, auditable AI systems, drawing on experience from research projects that have contributed to major international computer systems conferences. Together, Vivian and Shuang explore what it takes to keep AI current in a world where people turn to search engines, chatbots, and AI assistants for everything from schoolwork to health questions, why reliability matters so much as AI becomes part of everyday decision-making, and what responsible AI design looks like in practice. This episode highlights both the technical challenge of keeping AI up to date and the broader stakes for trust in the tools we rely on every day.
