Abstract
Matrix reduction and formal concept analysis are two complementary mathematical tools for data analysis. In this paper, we study the reduction of the concept lattices and implication bases based on matrix reduction and propose two kinds of reduction methods for the above concept lattices. We analyse the benefits which we obtain by using several methods of matrix factorisation to reduce the dimension of input data.
