What is the difference between KL-divergence, JS-divergence, Wasserstein distance and MMD?

I was reading about different distribution distances, and came across

  • Kullback-Leibler divergence
  • Jensen-Shannon divergence
  • Wasserstein distance
  • Maximum mean discrepancy (MMD)

The book was too abstract for me to absorb. What are the differences between them, actually?

1Do you care about those four distances specifically or are you asking about distances in general and why there are multiple? – Alex L – 2019-03-17T03:37:01.110
