It is shown that the Vapnik-Chervonenkis (VC-) dimension of the set of half-spaces in $\\mathbb{R}^n$ generated by $k$-sparse vectors is bounded below by $k \\lg (n/k)$ and above by $2k \\lg (n/k)$, plus some round-off terms. By coupling this estimate with well-established results in PAC learning theory, we show that a consistent algorithm can recover a $k$-sparse vector with $O(k \\lg (n/k))$ measurements, given only the signs of the measurement vector.
