WebAbstract: The k-undercover Boolean matrix factorization problem aims to approximate a m×n Boolean matrix X as the Boolean product of an m×k and a k×n matrices A B such that X is a cover of A B, i.e., no representation error is allowed on the 0’s entries of the matrix X. WebNote that BMM can be computed using an algorithm for integer matrix multiplication, and so we have BMM for n !nmatrices is in O(n ) time, where !<2:373 (the current bound for integer matrix multiplication). Most theoretical fast matrix multiplication algorithms are impractical. Therefore, so called \combina-torial algorithms" are desirable.
