At the request of the authors, the article titled “Sparsity Based Locality-Sensitive Discriminative Dictionary Learning for Video Semantic Analysis” [1] has been retracted. The article was previously published as “Benuwa, BB., Zhan, Y., Liu, J. et al. Multimed Tools Appl (2018).”

Though the two articles differ comparatively in baseline approaches and experimental outcomes, they both have the same methodological approach or formulations (i.e., sparse based locality-sensitive discriminative learning technique) for video semantic analysis. The authors are improving on the article with kernel learning.

The publisher apologizes that a request from one of the coauthors to withdraw the article while it was in production was not acted upon.
