Optimizing affinity-based binary hashing using auxiliary coordinates

NeurIPS 2016 Ramin RaziperchikolaeiMiguel Á. Carreira-Perpiñán

In supervised binary hashing, one wants to learn a function that maps a high-dimensional feature vector to a vector of binary codes, for application to fast image retrieval. This typically results in a difficult optimization problem, nonconvex and nonsmooth, because of the discrete variables involved... (read more)
