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titled “Sparsity Based Locality-Sensitive Discriminative Dictionary Learning for Video Semantic Analysis” [1] has been retracted.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). https://doi.org/10.1007/s11042-018-6417-3.”
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.
