- Abstract: NASA's Kepler Space Telescope has been instrumental in the task of finding
the presence of exoplanets in our galaxy. This search has been supported by
computational data analysis to identify exoplanets from the signals received by
the Kepler telescope. In this paper, we consider building upon some existing
work on exoplanet identification using residual networks for the data of the
Kepler space telescope and its extended mission K2. This paper aims to explore
how deep learning algorithms can help in classifying the presence of exoplanets
with less amount of data in one case and a more extensive variety of data in
another. In addition to the standard CNN-based method, we propose a Siamese
architecture that is particularly useful in addressing classification in a
low-data scenario. The CNN and ResNet algorithms achieved an average accuracy
of 68% for three classes and 86% for two-class classification. However, for
both the three and two classes, the Siamese algorithm achieved 99% accuracy.

young planets in dusty protoplanetary discs [49.1574468325115]
We develop DBNets, a tool to quickly infer the mass of allegedly embedded planets from protoplanetary discs.
We extensively tested our tool on out-of-distribution data.
DBNets can identify inputs strongly outside its training scope returning an uncertainty above a specific threshold.
It can be reliably applied only on discs observed with inclinations below approximately 60deg, in the optically thin regime.

We find a small fraction of these transits contain moon-like signals, though we caution against strong inferences of the exomoon occurrence rate from this result.

Current neural architecture search (NAS) algorithms still require expert knowledge and effort to design a search space for network construction.
We propose a novel differentiable evolutionary framework named AutoSpace, which evolves the search space to an optimal one.
With the learned search space, the performance of recent NAS algorithms can be improved significantly compared with using previously manually designed spaces.

We introduce a new machine learning based technique to detect exoplanets using the transit method.
For Kepler data, the method is able to predict a planet with an AUC of 0.948, so that 94.8 per cent of the true planet signals are ranked higher than non-planet signals.
For the Transiting Exoplanet Survey Satellite (TESS) data, we found our method can classify light curves with an accuracy of 0.98, and is able to identify planets with a recall of 0.82 at a precision of 0.63.
