BigBayes
As datasets grow ever larger in scale, complexity and variety, there is an increasing need for powerful machine learning and statistical techniques that are capable of learning from such data. Bayesian nonparametrics is a promising approach to data analysis that is increasingly popular in machine learning and statistics. Bayesian nonparametric models are highly flexible models with infinitedimensional parameter spaces that can be used to directly parameterise and learn about functions, densities, conditional distributions etc. This ERC funded project aims to develop Bayesian nonparametric techniques for learning rich representations from structured data in a computationally efficient and scalable manner.
