However, an exact factorization is rarely found in the literature. In this paper, we introduce a new algorithm named XBMaD (Xorbased Boolean Matrix Decomposition) where the addition operator is defined as the exclusive OR (Xor).

An evaluation comparing XBMaD and classic ORbased methods suggested that XBMAD performed equal or in most cases more accurately and faster.
