Behavior of the Concept Lattice Reduction to visualizing data after using matrix decompositions
Original language description
High complexity of formal concept analysis algorithms and lattice construction algorithms are main problems today. If we want to compute all concepts from huge incidence matrix, complexity plays a great role. In some cases, we do not need to compute allconcepts, but only some of them. Our research focuses on behavior of the Concept Lattice Reduction after using matrix decompositions. Modified matrix has lower dimensions and acts as input for some known algorithms for lattice construction. In this paperwe want to describe the deferent between methods for matrix decompositions and describe their influence on the concept lattice.
