Quotient Cube: A Semantic Approach to Data Cube Compression
Laks V.S. LakshmananUniversity of British Columbia In this talk, I will describe a lossless compression technique inspired by concepts from lattice theory. Specifically, I will discuss the Quotient Cube, which is the factor lattice obtained when the cube lattice is “divided” by a certain equivalence relation. The idea is to represent cube cells by choosing…
