Bayesian sparse reconstruction: a brute-force approach to astronomical imaging and machine learning

1 code implementation12 Sep 2018 Edward Higson, Will Handley, Michael Hobson, Anthony Lasenby

Our approach can also be readily applied to neural networks, where it allows the network architecture to be determined by the data in a principled Bayesian manner by treating the number of nodes and hidden layers as parameters.

Diagnostic Tests for Nested Sampling Calculations

3 code implementations16 Apr 2018 Edward Higson, Will Handley, Mike Hobson, Anthony Lasenby

Nested sampling is an increasingly popular technique for Bayesian computation - in particular for multimodal, degenerate and high-dimensional problems.

Dynamic nested sampling: an improved algorithm for parameter estimation and evidence calculation

2 code implementations11 Apr 2017 Edward Higson, Will Handley, Mike Hobson, Anthony Lasenby

We introduce dynamic nested sampling: a generalisation of the nested sampling algorithm in which the number of "live points" varies to allocate samples more efficiently.

Sampling Errors in Nested Sampling Parameter Estimation

2 code implementations28 Mar 2017 Edward Higson, Will Handley, Mike Hobson, Anthony Lasenby

Sampling errors in nested sampling parameter estimation differ from those in Bayesian evidence calculation, but have been little studied in the literature.
