Factor analysis of dynamic PET images: beyond Gaussian noise
Yanna Cruz Cavalcanti, Thomas Oberlin, Nicolas Dobigeon +4
Factor analysis has proven to be a relevant tool for extracting tissue time-activity curves (TACs) in dynamic PET images, since it allows for an unsupervised analysis of the data.…
Coupled dictionary learning for unsupervised change detection between multi-sensor remote sensing images
Vinicius Ferraris, Nicolas Dobigeon, Yanna Cavalcanti +2
Archetypal scenarios for change detection generally consider two images acquired through sensors of the same modality. However, in some specific cases such as emergency situations,…
Reconstruction of partially sampled multi-band images - Application to STEM-EELS imaging
Étienne Monier, Thomas Oberlin, Nathalie Brun +3
Electron microscopy has shown to be a very powerful tool to map the chemical nature of samples at various scales down to atomic resolution. However, many samples can not be analyze…
Negative Binomial Matrix Factorization for Recommender Systems
Olivier Gouvert, Thomas Oberlin, Cédric Févotte
We introduce negative binomial matrix factorization (NBMF), a matrix factorization technique specially designed for analyzing over-dispersed count data. It can be viewed as an exte…
