WebFisher information distance: A geometrical reading. João Eloir Strapasson. 2014, Discrete Applied Mathematics. Information geometry is a research field that has provided framework and enlarged the perspective of analysis for a wide variety of domains, such as statistical inference, information theory, mathematical programming, neurocomputing ... WebThe Hessian of the KL divergence is so-called Fisher's information matrix. That's the connection. KL divergence is never a metric. Metric has a specific and rigorous definition in mathematics. Some people call it a distance, but they are using it in a colloquial way. It is an example in a class of divergences called Bregman divergence.
