Exploiting auxiliary distributions in stochastic uni

چکیده
This paper describes a method for estimating conditional probability distributions over the parses of uniication-basedd grammars which can utilize auxiliary distributions that are estimated by other means. We show how this can be used to incorporate information about lexical selectional preferences gathered from other sources into Stochastic Uniication-basedd Grammars (SUBGs). While we apply this estimator to a Stochastic Lexical-Functional Grammar, the method is general, and should be applicable to stochastic versions of HPSGs, categorial grammars and transformational grammars .

متن کاملHessian Stochastic Ordering in the Family of multivariate Generalized Hyperbolic Distributions and its Applications
In this paper, random vectors following the multivariate generalized hyperbolic (GH) distribution are compared using the hessian stochastic order. This family includes the classes of symmetric and asymmetric distributions by which different behaviors of kurtosis in skewed and heavy tail data can be captured. By considering some closed convex cones and their duals, we derive some necessary and s...
متن کاملEfficient reversible jump MCMC for Bayesian object recognition
Computational efficiency is a bottleneck for the use of stochastic geometry models in high-level Bayesian object recognition. In this paper we examine various approaches to reversible jump MCMC that lead to higher acceptance rates than the traditional approach of using a uniform proposal density. This is achieved by exploiting information about the posterior gained through a deterministic image...
متن کاملImproving Semi-Supervised Learning with Auxiliary Deep Generative Models
Abstract Deep generative models based upon continuous variational distributions parameterized by deep networks give state-of-the-art performance. In this paper we propose a framework for extending the latent representation with extra auxiliary variables in order to make the variational distribution more expressive for semi-supervised learning. By utilizing the stochasticity of the auxiliary var...
