Data mining and knowledge discovery can today be considered as stable fields with numerous efficient methods and studies that have been proposed to extract knowledge from data.

Compressive Mining: Fast and Optimal Data Mining in the Compressed Domain Michail Vlachos ·Nikolaos M. Freris ·Anastasios Kyrillidis Received: date / Accepted: date Abstract Real-world data typically contain repeated and periodic patterns. This suggests that they can be eﬀectively represented and compressed using only a few coeﬃcients of an appropriate basis (e.g., Fourier, Wavelets,etc ...
