Novel Statistical Inference Methods and Tools from Astrophysics.
- Speaker: Dr Roberto Trotta, Imperial College London.

- Location: Room 151, Birkbeck Main Building
In the last two decades, astrophysics and cosmology have become data-driven fields. Already today, our knowledge about the Universe is not limited by the amount of data we can acquire, but by our ability to interpret them statistically and extract answers to the questions that matter to us: What is the Universe made of? Where did it come from? What will its fate be?
In this talk I will briefly review how the pursuit of the answers to some of the most fundamental scientific questions ever has led astrophysicists to develop statistical tools and algorithms with much wider applicability than the research for which they were invented. From structured Bayesian models to model selection tools, from object detection to classification problems, I will delineate how the emerging discipline of astrostatistics can help solve real world problems.
