DOI: 10.1080/03610926.2020.1740737
Abstract: Abstract The raise regression was presented as an alternative methodology to estimate models with collinearity, it is to say, when columns of matrix X are nearly linearly dependent. This method consists in transforming matrix X… read more here.

DOI: 10.1109/tsp.2021.3071560
Abstract: Many problems in data science can be treated as estimating a low-rank matrix from highly incomplete, sometimes even corrupted, observations. One popular approach is to resort to matrix factorization, where the low-rank matrix factors are… read more here.
