In information geometry, a divergence is a kind of statistical distance: a binary function which establishes the separation from one probability distribution to another on a statistical manifold. The simplest divergence is squared Euclidean distance (SED), and divergences can be viewed as generalizations … See more Given a differentiable manifold $${\displaystyle M}$$ of dimension $${\displaystyle n}$$, a divergence on $${\displaystyle M}$$ is a $${\displaystyle C^{2}}$$-function 1. See more The use of the term "divergence" – both what functions it refers to, and what various statistical distances are called – has varied significantly over time, but by c. 2000 had settled on … See more Many properties of divergences can be derived if we restrict S to be a statistical manifold, meaning that it can be parametrized with a finite-dimensional coordinate system … See more The two most important divergences are the relative entropy (Kullback–Leibler divergence, KL divergence), which is central to See more • Statistical distance See more WebJan 7, 2024 · Also known as the KL divergence loss function is used to compute the amount of lost information in case the predicted outputs are utilized to estimate the expected target prediction. It outputs the proximity of two probability distributions If the value of the loss function is zero, it implies that the probability distributions are the same.

WebIn statistics, specifically regression analysis, a binary regression estimates a relationship between one or more explanatory variables and a single output binary variable. ... The … Cross-entropy can be used to define a loss function in machine learning and optimization. The true probability is the true label, and the given distribution is the predicted value of the current model. This is also known as the log loss (or logarithmic loss or logistic loss); the terms "log loss" and "cross-entropy loss" are used interchangeably. More specifically, consider a binary regression model which can be used to classify observation…
