Open AccessClassical signal processing techniques are developed under prior statistical knowledge of the kind of data we are processing. Unfortunately, one does not know too much about reality in practice, therefore inferring information ...
Contributions to anomaly detection and correction in co-evolving data streams via subspace learning López Molina, Carlos Alejandro (Universitat Politècnica de Catalunya, 2020-07)
12 months embargoDuring decades, estimation and detection tasks in many Signal Processing and Communications applications have been significantly improved by using subspace and component-based techniques. More recently, subspace methods ...
