Diffusion Models

Speaker: Siyu Yao | Dept. of Philosophy, Shanghai Jiao Tong University

Abstract: 

Deep learning (DL) is a powerful scientific tool for classification, inference, and data emulation, but its opacity raises concerns about undermining epistemic virtues such as understanding and objectivity. Is it possible for scientists to retain understanding as DL permeates science? If so, what form of understanding is relevant? Throughout history, scientists often use complex “alien” tools effectively without full technical knowledge, relying on practical sense-making strategies.

Speaker: André Curtis-Trudel | Dept. of Philosophy, University of Cincinnati

Abstract: 

Recent philosophy frames this as “pragmatic understanding,” where scientists learn how to apply tools without fully grasping their inner workings. Drawing on interviews with astronomers using AI, we identify strategies of establishing pragmatic understanding, such as embedding AI into existing methods, interpreting outputs through domain reasoning, developing design heuristics, testing performance, tracking errors, and fostering interdisciplinary collaboration. These practices show that understanding is plural and context-dependent. We argue that high-quality pragmatic understanding depends on building a diverse, interconnected set of practices, enabling reliable and generalizable use of DL through ongoing methodological learning across domains.
