Computational Statistics and Machine Learning
Advancing the theory, methodology, algorithms and applications to modern, computationally intensive, approaches for statistical inference.
We encompasses topics from machine learning methods for adaptive systems and flexible modelling, to optimisation and simulation based approaches to solve intractable computational problems of relevance to statistics, such as variational or Monte Carlo methods and simulation-based inference.
The need for advanced algorithms is a reality in any modern day application of statistics, be it in finance, social science, natural sciences or beyond. The development of simulation and optimisation algorithms, as well as the analysis of their properties in the context of statistical inference, is a core mission of our group. Our research has advanced the applicability of models that imply complex posterior distributions in Bayesian inference, or more generally those that involve sophisticated generative models required to faithfully capture the structure of real data.
Machine learning originated from research in artificial intelligence, where historically the focus has been on data-driven approaches for the development of autonomous systems. However, it has grown to affect science and society in many high-stakes applications that require careful statistical diligence and a deep understanding of the specific needs raised by real-world data. Our group advances machine learning methodology by embracing the adaptability and generality of AI-inspired research with the expectations of stakeholders who require robustness and uncertainty quantification in their applications.
