In this paper, we initiate the study of streaming and online MAP inference problems for Non-symmetric Determinantal Point Processes (NDPPs) and provide one-pass algorithms for solving these problems. In the streaming setting, data points arrive in an arbitrary order and the algorithms are constrained to use a single-pass over the data as well as sub-linear memory, and only need to output a valid solution at the end of the stream. The online setting has an additional requirement of maintaining a valid solution at any point in time. We design new algorithms for these problems with provable guarantees and show that empirically, they perform comparably or even better than state-of-the-art offline algorithm while using substantially lower memory.
