Non-iterative solution for PARAFAC with a Toeplitz matrix factor
Non-iterative solution for PARAFAC with a Toeplitz matrix factor
Recently, tensor signal processing has received an increased attention, particularly in the context of wireless communication applications. The so-called PARAllel FACtor (PARAFAC) decomposition is certainly the most used tensor tool. In general, the parameter estimation of a PARAFAC decomposition is carried out by means of the iterative ALS algorithm, which …
