Best of both: a hybridized centroid-medoid clustering heuristic
Although each iteration of the popular kMeans clustering heuristic scales well to larger problem sizes, it often requires an unacceptably-high number of iterations to converge to ...

New Fastest Linearly Independent Transforms over GF(3)
New fastest linearly independent (LI) transforms for ternary functions are introduced in this paper. The transforms operate over Galois Field (3) (GF(3)) and have smaller computat...
