- Yandong Wen, Mahmoud Al Ismail, B. Raj, Rita Singh. 2018. Optimal Strategies for Matching and Retrieval Problems by Comparing Covariates. Abstract: In many retrieval problems, where we must retrieve one or more entries from a gallery in response to a probe, it is common practice to learn to do by directly comparing the probe and gallery entries to one another. In many situations the gallery and probe have common covariates -- external variables that are common to both. In principle it is possible to perform the retrieval based merely on these covariates. The process, however, becomes gated by our ability to recognize the covariates for the probe and gallery entries correctly.
