Independent draws from a $d$-dimensional spherical Gaussian distribution are distributed across users, each holding one sample. A central server seeks to distinguish between the two hypotheses: the distribution has zero mean, or the mean has $ell_2$-norm at least $varepsilon$, a pre-specified threshold. However, the users can each transmit at most $ell$ bits to the server. This is a distributed variant of the classic problem of detecting signal in white noise.
We study this distributed testing problem with and without the availability of a common randomness shared by the users. We design schemes with and without such shared randomness. We then obtain lower bounds for protocols with public randomness, which are tight when $ell=O(1)$. We finally conclude with several conjectures and open problems.
