泛函尺度律：大模型尺度现象的动力学解释
演讲人： 吴磊 【北京大学】时间：14:00-15:00, Oct 24, 2025 (Tue)地点：吕大龙楼701会议室内容：大模型尺度律揭示：性能随训练数据规模和计算量的增长呈现出可预测的幂律提升。这一规律深刻推动了现代人工智能的发展，但长期停留在经验观察层面，缺乏理论理解。为探究其成因，我们引入幂律核回归（power-law kernel regression）这一简化模型，作为理论原型来抽象尺度现象的关键机制。基于该模型的动力学推导，我们提出泛函尺...

Generalized Planar and Toric Codes as High-Efficiency Quantum Memories
演讲人：陈昱安 [北京大学]时间： 16:00-17:00, Oct 21, 2025 (Tue)地点：RM S327, MMW Building内容：The Kitaev toric code remains a benchmark for fault-tolerant quantum computation, yet standard techniques for increasing its logical dimension—lattice surgery, punctures, or concatenation—incur substantial qubit overhead. I will present a unified construction and analysis framework that alleviates ...
