A Probabilistic Model for Data Cube Compression and Query Approximation
... Since data cubes are nothing but multi-way tables, we propose to analyze the potential of a probabilistic model- ing technique, called non-negative multi-way array factor- ization, for approximating ...

Data Cube Approximation and Mining using Probabilistic Modeling
... One key difference between both approaches is that LLM focuses on variables, while NMF focuses on modalities. Indeed, for each identified interaction, LLM keeps all modalities of the relevant dimensions. On the contrary, ...
