Affine Invariant Divergences associated with Composite Scores and its Applications
composite score divergence Bregman score H¨older score affine invariance
2013/6/14
In statistical analysis, measuring a score of predictive performance is an important task. In many scientific fields, appropriate scores were tailored to tackle the problems at hand. A proper score is...
Alpha/Beta Divergences and Tweedie Models
Tweedie distributions variance functions alpha/betadivergences deviance.
2012/11/22
We describe the underlying probabilistic interpretation of alpha and beta divergences. We first show that beta divergences are inherently tied to Tweedie distributions, a particular type of exponentia...
Dual divergences estimation for censored survival data
Robust estimation Minimum divergence estimators Kaplan-Meier estimator
2011/7/5
This paper is devoted to robust estimation based on dual divergences estimators for parametric models in the framework of right censored data. We give limit laws of the proposed estimators and examine...
General bootstrap for dual phi-divergences estimates
Bootstrap consistency weighted bootstrap Kaplan-Meier
2011/7/5
A general notion of bootstrapped $\phi$-divergences estimates constructed by exchangeably weighting sample is introduced.
A Finite-Time Analysis of Multi-armed Bandits Problems with Kullback-Leibler Divergences
Finite-Time Multi-armed Bandits Problems Kullback-Leibler Divergences
2011/6/20
We consider a Kullback-Leibler-based algorithmfor the stochastic multi-armed bandit prob-
lem in the case of distributions with finite supports (not necessarily known beforehand),
whose asymptotic r...
Ultraviolet Divergences in Cosmological Correlations
Ultraviolet Divergences Cosmological Correlations
2010/12/23
A method is developed for dealing with ultraviolet divergences in calculations of cosmological correlations, which does not depend on dimensional regularization. An extended version of the WKB approx...

2010/12/21
We construct finite mass, asymptotically flat black hole solutions in d = 5 Einstein–Yang-Mills–Chern-Simons theory. Our results indicate the existence of a second order phase transition between Reiss...

A method is developed for dealing with ultraviolet divergences in calculations of cosmological correlations, which does not depend on dimensional regularization. An extended version of the WKB approxi...
Divergences in the 2-qubits' space: Werner and Thermal states
Jensen-Shannono divergence Heisenberg model
2010/9/13
We revisit the notion of using divergences, or relative-entropies, as measures of the distance between two mixed states, with special emphasis on power-law entropies. We analyze the Csisz´ar and...

family of statistical symmetric divergences Jensen's inequality
2010/12/16
We introduce a novel parametric family of symmetric information-theoretic distances based on Jensen's inequality on a convex generator that uni es Je reys divergence with Jensen-Shannon divergence for...
Lower bounds for the minimax risk using $f$-divergences and applications
Minimax lower bounds f-divergences Fano’sinequality Pinsker’s inequality Reconstruction from supportfunctions
2010/3/10
A new lower bound involving f-divergences between
the underlying probability measures is proved for the minimax
risk in estimation problems. The proof just uses the convexity
of the function f and ...
Convergences and/or Divergences of Labor Law Systems:The View from Australia
Convergences and/or Divergences Labor Law Systems View from Australia
2009/11/6
When asked to describe Australian employment law, most
foreign observers will explain that a unique form of compulsory
conciliation and arbitration grew up as the centerpiece of this nation’s
labor...

2009/7/13
The functions, convergences, and divergences of Italian allora and French alors are analyzed in
two Italian texts (the Novellino, in Old Italian, and Paso Doble, in Modern Italian) and their
French ...
A Lower Bound on Arbitrary f--Divergences in Terms of the Total Variation
Lower Bound Arbitrary f--Divergences Total Variation
2010/3/19
An important tool to quantify the likeness of two probability measures
are f–divergences, which have seen widespread application in statistics
and information theory. An example is the total variati...
Inhibitors of Phosphoinositide 3-Kinase, LY294002 and Wortmannin, Affect Sperm Capacitation and Associated Phosphorylation of Proteins Differently：Ca2+-Dependent Divergences
Spermatozoa signal transduction Akt
2008/12/22
Sperm capacitation is regulated by multiple pathways that also control sperm motility and tyrosine (Tyr) phosphorylation of several sperm proteins. Among the reported pathways, phosphoinositide 3-ki...
