Non-negative Sparse and Collaborative Representation for Pattern Classification. (arXiv:1908.07956v3 [cs.CV] UPDATED)

Sparse representation (SR) and collaborative representation (CR) have been
successfully applied in many pattern classification tasks such as face
recognition. In this paper, we propose a novel Non-negative Sparse and
Collaborative Representation (NSCR) for pattern classification. The NSCR
representation of each test sample is obtained by seeking a non-negative sparse
and collaborative representation vector that represents the test sample as a
linear combination of training samples. We observe that the non-negativity can
make the SR and CR more discriminative and …
