	abstract = {<p>In previous papers [4, 6] we have claimed that for each function which is efficiently Turing computable there exists a deep and sparse network which approximates it arbitrarily well. We also claimed a key role for compositional sparsity in this result. Though the general claims are correct some of our statements may have been imprecise and thus potentially misleading. In this short paper we wish to formally restate our claims and provide definitions and proofs.</p>
