Memory-Efficient Centroid Decomposition for Long Time Series

1 code implementation IEEE 30th International Conference on Data Engineering (ICDE) 2017 Mourad Khayati, Michael Böhlen, Johann Gamper

The Centroid Decomposition (CD) approximates the Singular Value Decomposition, but does not scale to long time series because of the quadratic space complexity of the sign vector computation.

CORAD: Correlation-Aware Compression of Massive Time Series using Sparse Dictionary Coding

1 code implementation Big Data 2019 Abdelouahab Khelifati, Mourad Khayati, Philippe Cudré-Mauroux

In this work, we demonstrate how one can leverage the correlation across several related time series streams to both drastically improve the compression efficiency and reduce the accuracy loss. We present a novel compression algorithm for time series streams called CORAD (CORelation-Aware compression of time series streams based on sparse Dictionary coding).
