Approximate Bayesian Inference for Psychometric Functions using MCMC Sampling

In psychophysical studies the psychometric function is used to model the relation between the physical stimulus intensity and the observer’s ability to detect or discriminate between stimuli of different intensities. In this report we propose the use of Bayesian inference to extract the information contained in experimental data estimate the parameters of psychometric functions. Since Bayesian ...

Bayesian Nonparametric Weighted Sampling Inference

It has historically been a challenge to perform Bayesian inference in a design-based survey context. The present paper develops a Bayesian model for sampling inference in the presence of inverse-probability weights. We use a hierarchical approach in which we model the distribution of the weights of the nonsampled units in the population and simultaneously include them as predictors in a nonpara...

A Bayesian Nonparametric Approach to Multisensory Perception

We propose a Bayesian nonparametric model of multisensory perception based upon the Indian buffet process. The model includes a set of latent variables that learn multisensory features from unisensory data. The model is highly flexible because it makes few statistical assumptions. In particular, the number of latent multisensory features is not fixed a priori. Instead, this number is estimated ...

A Nonparametric Bayesian Approach to Inverse Problems

of a known kernel k(ω, λ). The problem is difficult in part because the integral operator K : Γ 7→ G is smoothing, making the “inverse problem” K−1 : G 7→ Γ ill-posed in the sense that small changes in G may be associated with large changes in Γ. The most common approaches to solving Equation (1) for the unknown Γ begin by approximating this infinite-dimensional continuous problem with the fini...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
