Center node: "the vc dimension of similarity hypotheses spaces"
  Abstract: Given a set $X$ and a function $h:X\longrightarrow\{0,1\}$ which labels each element of $X$ with either $0$ or $1$, we may define a function $h^{(s)}$ to measure the similarity of pairs of points in $X$ according to $h$. Specifically, for $h\in \{0,1\}^X$ we define $h^{(s)}\in \{0,1\}^{X\times X}$ by $h^{(s)}(w,x):= \mathbb{1}[h(w) = h(x)]$. This idea can be extended to a set of functions, or hypothesis space $\mathcal{H} \subseteq \{0,1\}^X$ by defining a similarity hypothesis space $\mathcal{H}^{(s)}:=\{h^{(s)}:h\in\mathcal{H}\}$. We show that ${{vc-dimension}}(\mathcal{H}^{(s)}) \in \Theta({{vc-dimension}}(\mathcal{H}))$.
