The model described in this paper belongs to the family of non-negative
matrix factorization methods designed for data representation and dimension
reduction. In addition to preserving the data positivity property, it aims also
to preserve the structure of data during matrix factorization. The idea is to
add, to the NMF cost function, a penalty term to impose a scale relationship
between the pairwise similarity matrices of the original and transformed data
points. The solution of the new model involves deriving …
