TL;DR: A novel longitudinal multimodal corpus of physiological and behavioral data collected from direct clinical providers in a hospital workplace to understand individual-specific constructs such as job performance, interpersonal interaction, and well-being of hospital workers over time in their natural day-to-day job settings is presented.

TL;DR: The Q-normalized graph Laplacian is introduced, and the RA-GFT achieves better complexity-performance trade-offs than previous approaches, and outperforms the Region Adaptive Haar Transform by up to 2.5 dB, with a small complexity overhead.

TL;DR: The GraSP toolbox aims at processing and visualizing graphs and graphs signal with ease, and this demo shows those capabilities using several examples from the literature and from the own experiments.

TL;DR: This paper presents a metric to assess local stationarity using projections on localized atoms on the graph and takes advantage of the knowledge of the spectrum of the atoms to give a new power spectrum estimator.
