WebJun 14, 2024 · I am trying to compute the information length or distance induced by the Fisher information metric on the statistical manifold of the categorical distribution (the interior of the n-dimensional simplex). I have checked each part of my computation several times. However, the result I obtain is dependent on my original choice of chart.

Fisher information - Wikipedia
WebDivergence functions are the non-symmetric “distance” on the manifold, Μθ, of parametric probability density functions over a measure space, (Χ,μ). Classical information geometry prescribes, on Μθ: (i) a Riemannian metric given by the Fisher information; (ii) a pair of dual connections (giving rise to the family of α-connections) that preserve the metric … WebIt is not always possible to calculate expected Fisher information. Some-times you can’t do the expectations in (7.8.9) and (7.8.10) in DeGroot and Schervish. But if you can … health for life crimson
