报告题目:VC dimension and its applications Ⅳ
报告摘要: This series is an introduction to Vapnik–Chervonenkis dimension (VC dimension for short). VC dimension is a measure for combinatorial complexity of a family of sets, playing a pivotal role in learning theory and computational geometry. We will focus on its applications in extremal combinatorics, starting with the classics e.g. Sauer–Shelah lemma, its use in epsilon-net etc. We aim to also survey some recent results utilizing VC dimension including topics like chi-boundedness in structural graph theory and chromatic thresholds in extremal graph theory.
