PARAFAC2 with constraints in all modes

Written By Evrim Acar Ataman

We have introduced an AO-ADMM (alternating optimization- alternating direction method of multipliers)-based algorithm for fitting a PARAFAC2 model with constraints in all modes.

See the paper by our PhD students Marie Roald and Carla Schenker in collaboration with Jeremy Cohen, Rasmus Bro, Tulay Adali and Vince Calhoun:
