报告题目：Barron Space for Graph Convolution Neural Networks

主讲人：孙颀彧教授

时间：2024年6月5日（周三）下午4:30-5:30

地点：花江校区慧谷4号楼3楼310报告厅

报告摘要：

In this talk, we introduce a Barron space of functions on a compact domain of graph signals, discuss its various properties, such as reproducing kernel Banach space property and universal approximation property. We will also discuss well approximation property of functions in the Barron space by outputs of some graph convolution neural networks, and learnability of functions in the Barron space from their random samples.
