In the compressive phase retrieval problem, the goal is to reconstruct a sparse or approximately k-sparse vector x ∈ R n given access to y = |Φ x |, where |v| denotes the vector obtained from taking the absolute value of v ∈ R n coordinatewise. In this paper we present sublinear-time algorithms for...
