Boundary Crossing Probabilities for General Exponential Families [PDF]

open access: yesMathematical Methods of Statistics, 2017
We consider parametric exponential families of dimension K on the real line. We study a variant of boundary crossing probabilities coming from the multi-armed bandit literature, in the case when the real-valued distributions form an exponential family of

$q$-Exponential Families [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2004
We develop an analog of the exponential families of Wilf in which the label sets are finite dimensional vector spaces over a finite field rather than finite sets of positive integers. The essential features of exponential families are preserved, including the exponential formula relating the deck enumerator and the hand enumerator.

Exponential families of mixed Poisson distributions [PDF]

open access: yes, 2006
If I=(I1,…,Id) is a random variable on [0,∞)d with distribution μ(dλ1,…,dλd), the mixed Poisson distribution MP(μ) on View the MathML source is the distribution of (N1(I1),…,Nd(Id)) where N1,…,Nd are ordinary independent Poisson processes which are also ...

On Hölder Projective Divergences

open access: yesEntropy, 2017
We describe a framework to build distances by measuring the tightness of inequalities and introduce the notion of proper statistical divergences and improper pseudo-divergences.

Posteriors, conjugacy, and exponential families for completely random measures [PDF]

open access: yesBernoulli, 2014
We demonstrate how to calculate posteriors for general CRM-based priors and likelihoods for Bayesian nonparametric models. We further show how to represent Bayesian nonparametric priors as a sequence of finite draws using a size-biasing approach---and ...

Simple Exponential Family PCA [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2013
Principal component analysis (PCA) is a widely used model for dimensionality reduction. In this paper, we address the problem of determining the intrinsic dimensionality of a general type data population by selecting the number of principal components for a generalized PCA model.

Optimally approximating exponential families [PDF]

open access: yes, 2002
summary:This article studies exponential families $\mathcal{E}$ on finite sets such that the information divergence $D(P\|\mathcal{E})$ of an arbitrary probability distribution from $\mathcal{E}$ is bounded by some constant $D>0$.

Exponential dichotomy for evolution families on the real line

open access: yesAbstract and Applied Analysis, 2006
We give necessary and sufficient conditions for uniform exponential dichotomy of evolution families in terms of the admissibility of the pair (Lp(ℝ,X),Lq(ℝ,X)).

Deep Exponential Families

open access: yesCoRR, 2014
We describe \textit{deep exponential families} (DEFs), a class of latent variable models that are inspired by the hidden structures used in deep neural networks. DEFs capture a hierarchy of dependencies between latent variables, and are easily generalized to many settings through exponential families.

Exponential Family Embeddings

open access: yesCoRR, 2016
Word embeddings are a powerful approach for capturing semantic similarity among terms in a vocabulary. In this paper, we develop exponential family embeddings, a class of methods that extends the idea of word embeddings to other types of high-dimensional data.
