There is a shortage of multiwavelength and spectroscopic follow-up capabilities given the number of transient and variable astrophysical events discovered through wide-field optical surveys such as the upcoming Vera C. Rubin Observatory and its associated Legacy Survey of Space and Time. From the haystack of potential science targets, astronomers must allocate scarce resources to study a selection of needles in real time. Here we present a variational recurrent autoencoder neural network to… 
ParSNIP: Generative Models of Transient Light Curves with Physics-enabled Deep Learning
We present a novel method to produce empirical generative models of all kinds of astronomical transients from data sets of unlabeled light curves. Our hybrid model, which we call ParSNIP, uses a
Searching for Anomalies in the ZTF Catalog of Periodic Variable Stars
Periodic variables illuminate the physical processes of stars throughout their lifetime. Wide-field surveys continue to increase our discovery rates of periodic variable stars. Automated approaches
Detecting Dispersed Radio Transients in Real Time using Convolutional Neural Networks
Radio astronomy has entered an era of fast-cadence imaging [Prasad and Wijnholds, 2012]. Among others, this allows for transient hunting in the long-wavelength regime. For example, fast radio bursts
Autonomous Real-Time Science-Driven Follow-up of Survey Transients
Astronomical surveys continue to provide unprecedented insights into the time-variable Universe and will remain the source of groundbreaking discoveries for years to come. However, their data


RAPID: Early Classification of Explosive Transients using Deep Learning
We present Real-time Automated Photometric IDentification (RAPID), a novel time series classification tool capable of automatically identifying transients from within a day of the initial alert, to
Classifying Image Sequences of Astronomical Transients with Deep Neural Networks
The TAO-Net (for Transient Astronomical Objects Network) architecture achieves on the five-type classification task an average F1-score of 54.32, almost nine points higher than the F1 -score of 45.75 from the random forest classification on light curves.
Anomaly detection in gravitational waves data using convolutional autoencoders
This paper proposes an alternative generic method of studying GW data based on detecting anomalies that is not limited only to GW alone, but also includes glitches occurring in the real LIGO/Virgo dataset available at the Gravitational Waves Open Science Center.
SuperRAENN: A Semisupervised Supernova Photometric Classification Pipeline Trained on Pan-STARRS1 Medium-Deep Survey Supernovae
A novel semisupervised machine learning algorithm is trained to photometrically classify 2315 new SN-like light curves with host galaxy spectroscopic redshifts, which has an accuracy of 87% across five SN classes and macro-averaged purity and completeness of 66% and 69%, respectively.

The results suggest that spectroscopic campaigns used for training photometric classifiers should focus on typing large numbers of well-observed, intermediate-redshift transients, instead of attempting to type a sample of transients that is directly representative of the full data set being classified.
A classification algorithm for time-domain novelties in preparation for LSST alerts: Application to variable stars and transients detected with DECam in the Galactic Bulge.
With the advent of the Legacy Survey of Space and Time, time-domain astronomy will be faced with an unprecedented volume and rate of data. Real-time processing of variables and transients detected by
Supernova Photometric Classification Pipelines Trained on Spectroscopically Classified Supernovae from the Pan-STARRS1 Medium-deep Survey
This study serves as a guide to developing and training classification algorithms for a wide range of SN types with a purely empirical training set, particularly one that is similar in its characteristics to the expected LSST main survey strategy.
Anomaly detection in the Zwicky Transient Facility DR3
The results confirm the importance of combining automatic machine learning algorithms with domain knowledge in the construction of recommendation systems for astronomy.
Active Anomaly Detection for time-domain discoveries
The first application of adaptive machine learning to the identification of anomalies in a data set of non-periodic astronomical light curves is presented, providing the first evidence that AAD algorithms can play a central role in the search for new physics in the era of large scale sky surveys.
MOSFiT: Modular Open Source Fitter for Transients
This work introduces MOSFiT, a Python-based package that downloads transient datasets from open online catalogs, generates Monte Carlo ensembles of semi-analytical light curve fits to those datasets and their associated Bayesian parameter posteriors, and optionally delivers the fitting results back to those same catalogs to make them available to the rest of the community.
