title: Pseudo-dimension of real-valued functions
body: <p>For a set of real-valued functions <em>F = {f:X->R}</em>, How to calculate the *Pseudo-dimension of F?</p>
  
  <p>providing with an example will help my understanding. like cases 
  where <em>X</em> = {(x,y,z): <em>0</em>&lt;<em>x</em>&lt;<em>a</em>,0&lt;<em>y</em>&lt;<em>b,0</em>&lt;<em>z</em>&lt;<em>c</em>}</p>
  
  <p>*Pseudo-dimension is a generalization of VC-dimension</p>
