Next generation radio experiments such as LOFAR, HERA and SKA are expected to probe the Epoch of Reionization and claim a first direct detection of the cosmic 21cm signal within the next decade. Data volumes will be enormous and can thus potentially revolutionize our understanding of the early Universe and galaxy formation. However, numerical modelling of the Epoch of Reionization can be prohibitively expensive for Bayesian parameter inference and how to optimally extract information from… 
Implicit Likelihood Inference of Reionization Parameters from the 21 cm Power Spectrum
The first measurements of the 21 cm brightness temperature power spectrum from the epoch of reionization will very likely be achieved in the near future by radio interferometric array experiments
Emulating the global 21-cm signal from Cosmic Dawn and Reionization
The 21-cm signal of neutral hydrogen is a sensitive probe of the Epoch of Reionization (EoR), Cosmic Dawn, and the Dark Ages. Currently, operating radio telescopes have ushered in a data-driven era
Inferring the astrophysics of reionization and cosmic dawn from galaxy luminosity functions and the 21-cm signal
The properties of the first galaxies, expected to drive the Cosmic Dawn (CD) and the Epoch of Reionization (EoR), are encoded in the 3D structure of the cosmic 21-cm signal. Parameter inference from
Improved supervised learning methods for EoR parameters reconstruction
This work improves the accuracy of the predictions using several supervised learning methods: neural networks, kernel regressions, or ridge regressions based on a large training set of 21-cm power spectra, and compares the performances of these methods.
Parameter inference for weak lensing using Gaussian Processes and MOPED
A Gaussian Process (GP) emulator for the calculation of tomographic weak lensing band-power spectra and coefficients of summary data massively compressed with the MOPED algorithm is presented, and it is found that in this case, the inclusion of the GP uncertainty does not justify the extra computational expense in the test application.
Simulation-based Inference of Reionization Parameters from 3D Tomographic 21 cm Light-cone Images
This work adopts a trained 3D convolutional neural network to compress the 3D image data into informative summaries (DELFI-3D CNN) and shows that this method recovers accurate posterior distributions for the reionization parameters.
Efficient exploration and calibration of a semi-analytical model of galaxy formation with deep learning
This work implements a sample-efficient method for rapid and accurate emulation of semi-analytical galaxy formation models over a wide range of model outputs, and demonstrates that this method can be used to successfully calibrate the model parameters to a comprehensive list of observational constraints.
Fast likelihood-free cosmology with neural density estimators and active learning
NDEs are used to learn the likelihood function from a set of simulated datasets, with active learning to adaptively acquire simulations in the most relevant regions of parameter space on-the-fly, demonstrating the approach on a number of cosmological case studies.
ECoPANN: A Framework for Estimating Cosmological Parameters Using Artificial Neural Networks
It is proposed that the ANN can provide an alternative way to accurately and quickly estimate cosmological parameters, and ECoPANN can be applied to the research of cosmology and even other broader scientific fields.

Epoch of reionization 21 cm forecasting from MCMC-constrained semi-numerical models
The recent low value of Planck (2016) integrated optical depth to Thomson scattering suggests that the reionization occurred fairly suddenly, disfavoring extended reionization scenarios. This will
