Real-time analysis and classification of observational data collected within synoptic sky surveys is a huge challenge due to constant growth of data volumes. Machine learning techniques are often applied in order to perform this task automatically. The current bottleneck of transients detection in most surveys is the process of filtering numerous artifacts from candidate detection. We present a new method for automated artifact filtering based on hierarchical unsupervised classifier employing…

ANTARES: Time-Domain Discovery in the Era of LSST
The ANTARES project is a joint venture between NOAO and the University of Arizona Computer Science Department to develop a software infrastructure system to process time-domain events automatically at the scale and rate that LSST will generate them.
From CPU to FPGA — Acceleration of self-organizing maps for data mining
In this study, ARM-based SoCs achieved the highest efficiency for small network sizes while FPGAs and GPGPUs perform best for large data sets and large simulations especially benefit from the FPGA implementation, which outperforms the optimized CPU implementation by a factor of 220 and provides a 28-times higher energy efficiency.
Machine-learning-based Brokers for Real-time Classification of the LSST Alert Stream
This paper aims to provide a history of radio astronomy in the Solar System from 1979 to 2002, a period chosen in order to explore its origins as well as specific cases up to and including the Large Hadron Collider.


Data Mining and Machine-Learning in Time-Domain Discovery & Classification
The emerging reliance on computation and machine learning is a general one, but the time-domain aspect of the data and the objects of interest presents some unique challenges, which are described and explored in this chapter.
LSST: From Science Drivers to Reference Design and Anticipated Data Products
The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky, and mapping the Milky Way.
