# Deep-Learnt Classification of Light Curves

19 Sep 2017

As a result standard time series methods regularly used for financial and similar datasets are of little help and astronomers are usually left to their own instruments and techniques to classify light curves.

# Robust And Scalable Learning Of Complex Dataset Topologies Via Elpigraph

20 Apr 2018

Large datasets represented by multidimensional data point clouds often possess non-trivial distributions with branching trajectories and excluded regions, with the recent single-cell transcriptomic studies of developing embryo being notable examples.

# Efficient Optimization of Echo State Networks for Time Series Datasets

12 Mar 2019

Echo State Networks (ESNs) are recurrent neural networks that only train their output layer, thereby precluding the need to backpropagate gradients through time, which leads to significant computational gains.

# Convolutional neural networks: a magic bullet for gravitational-wave detection?

18 Apr 2019

In the last few years, machine learning techniques, in particular convolutional neural networks, have been investigated as a method to replace or complement traditional matched filtering techniques that are used to detect the gravitational-wave signature of merging black holes.

# Bayesian parameter estimation using conditional variational autoencoders for gravitational-wave astronomy

13 Sep 2019

Gravitational wave (GW) detection is now commonplace and as the sensitivity of the global network of GW detectors improves, we will observe $\mathcal{O}(100)$s of transient GW events per year.
