In Situ Calibration of Cross-Sensitive Sensors in Mobile Sensor Arrays Using Fast Informed Non-Negative Matrix Factorization

ICASSP 2021accepted

In this paper, we assume a set of mobile geolocalized sensor arrays observing an area over time. Each of these arrays consists of heterogeneous and cross-sensitive sensors, i.e., the sensor readings provided by one of such sensors also depends on the readings of the other sensors in the array. We fu…

Random Projection Streams for (Weighted) Nonnegative Matrix Factorization

ICASSP 2021accepted

Random projections recently became popular tools to process big data. When applied to Nonnegative Matrix Factorization (NMF), it was shown that, in practice, with the same compression level, structured random projections were more efficient than classical strategies based on, e.g., Gaussian compress…
