It has applications outside of machine learning too! I used symmetric Kullback–Leibler divergence for a project with photon number resolving single photon detectors during my PhD. I used it with an adjacency matrix to split a gaussian mixture model (modelling some data with multivariate gaussians) into a series of clusters. https://snsphd.online/chapter_04/section_05_results/#photon-number-discrimination https://snsphd.online/chapter_04/section_05_results/#photon-...
