A Fiat–Shamir Transformation From Duplex Sponges
演讲人：Michele Orrù [CNRS] 时间： 14:00-15:00, Mar 12, 2026 (Thu)地点： RM 1-222, FIT Building内容：We study a new Fiat-Shamir transformation based on an ideal permutation that minimizes permutation calls and aligns more closely with deployed systems. We show concrete bounds for soundness, knowledge soundness, and zero knowledge, revealing that indifferentiability -- the standard notion used ...

Scaling Trust without Trusting
演讲人：Binyi Chen时间：14:00-15:00, Feb 28, 2026 (Sat)地点： RM 1-222, FIT Building内容：In an era of AI and digitalization, we face a dual challenge in building trust while preserving privacy. For example, social platforms are flooded with unverifiable AI-generated content, and online services require users to excessively expose their personal data. Zero-Knowledge Succinct Proofs (ZK-SNARKs) ...

Rationality of multi-agent learning and uncertainty quantification for the generative models
演讲人：Yian Ma (马易安) [University of California, San Diego]时间：13:30-15:00, Dec 26, 2025 (Fri)地点：RM 1-222, FIT Building内容：In the first part of the talk, I will discuss an interesting phenomenon in multiagent learning, that the mixed Nash equilibria are uniformly stable if and only if they are collectively rational. This justifies the effusive use of multi-agent learning systems and r...

Pointwise Generalization in Deep Neural Networks
演讲人：Yunbei Xu [NUS]时间：11:00-12:00, Dec 23, 2025 (Tue)地点：RM 1-222, FIT Building内容：We address the fundamental question of why deep neural networks generalize by establishing a pointwise generalization theory for fully connected networks. This framework resolves long-standing barriers to characterizing the rich, nonlinear feature-learning regime and builds a new statistical foundation...
