How to find the size of an ϵ-net of a vector space?
Taken from paper "A Universal Law of Robustness via isoperimetry" by Bubeck and Sellke.
Theorem 3. Let $\mathcal{F}$ be a class of functions from $\mathbb{R}^{d} \rightarrow \mathbb{R}$ and ...

Hitting sets for sets of VC dimension d
Let $S$ be a collection of sets of binary vectors (in $\{0,1\}^m$) $S_1, S_2, \dotsc, S_t$ (say $t = O(m^d)$) each of VC dimension $d$. What can be said about the size of a hitting set $S_\text{hit}$ ...

How intrinsic is the $d^d$ term in the running time for constructing $\varepsilon$-nets in range spaces of VC-dimension d?
An $\varepsilon$-net for a range space $(X,\mathcal{R})$ is a subset $N$ of $X$ such that $N\cap R$ is nonempty for all $R\in \mathcal{R}$ such that $|X\cap R| \ge \varepsilon |X|$.
Given a range ...
