    • Energy efficient cosine similarity measures according to a convex cost function 

      Akbaş, C. E.; Günay, O.; Taşdemir K.; Çetin, A. E. (Springer London, 2017)
      We propose a new family of vector similarity measures. Each measure is associated with a convex cost function. Given two vectors, we determine the surface normals of the convex function at the vectors. The angle between ...
    • L1 norm based multiplication-free cosine similarity measures for big data analysis 

      Akbas, C.E.; Bozkurt, A.; Arslan, M.T.; Aslanoglu H.; Cetin, A.E. (Institute of Electrical and Electronics Engineers Inc., 2014)
      The cosine similarity measure is widely used in big data analysis to compare vectors. In this article a new set of vector similarity measures are proposed. New vector similarity measures are based on a multiplication-free ...
