Modelling dependency completion in sentence comprehension as a Bayesian hierarchical mixture process: A case study involving Chinese relative clauses

no code implementations2 Feb 2017 Shravan Vasishth, Nicolas Chopin, Robin Ryder, Bruno Nicenboim

We present a case-study demonstrating the usefulness of Bayesian hierarchical mixture modelling for investigating cognitive processes.

PAC-Bayesian AUC classification and scoring

no code implementations NeurIPS 2014 James Ridgway, Pierre Alquier, Nicolas Chopin, Feng Liang

We also extend our method to a class of non-linear score functions, essentially leading to a nonparametric procedure, by considering a Gaussian process prior.

The Poisson transform for unnormalised statistical models

no code implementations11 Jun 2014 Simon Barthelmé, Nicolas Chopin

Here we show that inferring the parameters of a unnormalised model on a space $\Omega$ can be mapped onto an equivalent problem of estimating the intensity of a Poisson point process on $\Omega$.

Bayesian matrix completion: prior specification

no code implementations5 Jun 2014 Pierre Alquier, Vincent Cottet, Nicolas Chopin, Judith Rousseau

While the behaviour of algorithms based on nuclear norm minimization is now well understood, an as yet unexplored avenue of research is the behaviour of Bayesian algorithms in this context.
