In this work, we focus on PARAFAC and Tucker decompositions of three-way tensors with non-negativity and/or sparseness constraints. By using an all-at-once optimization approach, we propose two decomposition algorithms which are robust to tensor order over-estimation errors, – a desired practical property when the tensor rank is unknown. Different algorithm versions are proposed depending on the desired constraint (or property) of the tensor factors or the core tensor. Finally, the performance of the algorithms are assessed via insightful simulation experiments on both simulated and real-life data. date: 2016 date_type: published official_url: http://dx.doi.org/10.1109/EUSIPCO.2016.7760629 full_text_status: restricted pres_type: lecture place_of_pub: Budapest, Hungary pagerange: 2151-2155 event_title: 24th European Signal Processing Conference (EUSIPCO) event_location: Budapest, Hungary event_dates: 29 August - 2 September event_type: conference refereed: TRUE citation: Nguyen, Viet Dung and Abed-Meraim, Karim and Nguyen, Linh Trung (2016) New robust algorithms for sparse non-negative three-way tensor decompositions.
