## Post-edited Were the foundations of measurement without theory laid in the 1920s?

In his 1947 essay, Tjalling Koopmans criticized the development of an empirical science that had no theoretical basis, what he referred to as measurement without theory. The controversy over the ...

## Post-edited Bayesian modelling

This tutorial will be a beginner’s introduction to Bayesian statistical modelling and analysis. Simple models and computational tools will be described, followed by a discussion about implementing ...

## Post-edited Interview at CIRM: Genevieve Walsh

'I am a geometric topologist, and I'm interested in problems in both geometric topology and geometric group theory. I study groups acting on spaces in a variety of contexts: groups acting on ...

## Post-edited ​​​Growth of normalizing sequences in limit theorems

​Assume that a renormalized Birkhoff sum $S_n f/B_n$ converges in distribution to a nontrivial limit. What can one say about the sequence $B_n$? Most natural statements in the literature involve ...

## Multi angle Signal processing for nonlinear diffractive imaging

Can modern signal processing be used to overcome the diffraction limit? The classical diffraction limit states that the resolution of a linear imaging system is fundamentally limited by one half of ...

## Multi angle Compressed sensing and high-dimensional approximation: progress and challenges

Many problems in computational science require the approximation of a high-dimensional function from limited amounts of data. For instance, a common task in Uncertainty Quantification (UQ) involves ...
