Rényi Divergence and Kullback-Leibler Divergence [PDF]
IEEE Transactions on Information Theory, 2014 Rényi divergence is related to Rényi entropy much like Kullback-Leibler divergence is related to Shannon's entropy, and comes up in many settings. It was introduced by Rényi as a measure of information that satisfies almost the same axioms as Kullback-Leibler divergence, and depends on a parameter that is called its order.

Beta-Divergence as a Subclass of Bregman Divergence [PDF]
IEEE Signal Processing Letters, 2011 In this paper, we present a complete proof that the β-divergence is a particular case of Bregman divergence. This little-known result makes it possible to straightforwardly apply theorems about Bregman divergences to β-divergences. This is of interest for numerous applications since these divergences are widely used, for instance in non-negative matrix

Neural Computation, 2016
In many areas of neural computation, like learning, optimization, estimation, and inference, suitable divergences play a key role. In this note, we study the conjecture presented by Amari ( 2009 ) and find a counterexample to show that the conjecture does not hold generally. Moreover, we investigate two classes of [Formula: see text]-divergence (Zhang,

Speciation may be considered as a kind of non-equilibrium phase transition which is caused by bifurcation at a critical point of instability. It can be shown that multiple branching of an evolutionary tree is highly improbable, since non-degenerate mathematical models describe only binary branchings.

Constructionist theories hold that learning will be deeper if students develop and share their own diverse understandings of a concept. College students are immersed in a community with its social norms, learning practices and an understanding of authority and the classroom contract.

Theory and Decision, 2011 A robust feature of models of electoral competition between two opportunistic, purely office-motivated parties is that both parties become indistinguishable in equilibrium. I this short note, I show that this strong connection between the office motivation of parties and their equilibrium choice of identical platforms depends on the following two ...

Divergence insufficiency is an unusual form of strabismus with esotropia and diplopia only at distance and single binocular vision at near. This retrospective case series describes the diagnosis and treatment of 7 patients and differentiates this clinical entity from other conditions.Seven healthy patients aged 9 to 41 years who developed acquired ...
