On frequent sets of Boolean matrices

Given a Boolean matrix and a threshold t, a subset of the
columns is frequent if there are at least t rows having a 1 entry in
each corresponding position. This concept is used in the algorithmic,
combinatorial approach to knowledge discovery and data mining. We
consider the complexity aspects ... more >>>

Nearly optimal solutions for the Chow Parameters Problem and low-weight approximation of halfspaces

The \emph{Chow parameters} of a Boolean function $f: \{-1,1\}^n \to \{-1,1\}$ are its $n+1$ degree-0 and degree-1 Fourier coefficients. It has been known since 1961 \cite{Chow:61, Tannenbaum:61} that the (exact values of the) Chow parameters of any linear threshold function $f$ uniquely specify $f$ within the space of all Boolean ... more >>>
