Popis:	Attribute reduction is a topic of interest in data analysis. In particular, in formal concept analysis attribute reductions are associated with equivalence relations defined on concept lattices. In this paper, we study the equivalence relations induced by attribute reductions with the goal of characterizing when the equivalence classes are not convex sublattices of the original concept lattice.
