We report the detection of 72 new pulses from the repeating fast radio burst FRB 121102 in Breakthrough Listen C-band (4-8 GHz) observations at the Green Bank Telescope. The new pulses were found with a convolutional neural network in data taken on August 26, 2017, where 21 bursts have been previously detected. Our technique combines neural network detection with dedispersion verification. For the current application we demonstrate its advantage over a traditional brute-force dedis- persion… Expand

Single-pulse Detection Algorithms for Real-time Fast Radio Burst Searches Using GPUs
This work quantified the signal loss introduced by single pulse detection algorithms which use boxcar filters and based on these results, they have designed two distinct "lossy" algorithms, which can process SKA-MID-like data 266x faster than real-time on a NVIDIA P100 GPU and 500x faster on aNVIDIA Titan V GPU with a mean signal power loss of 7%.

The detection of 1,652 independent bursts with a peak burst rate of 122 h-1, in 59.5 hours spanning 47 days is reported, and a peak in the isotropic equivalent energy distribution is found to be approximately 4.8 × 1037 erg at 1.25 GHz, below which the detection of bursts is suppressed. Expand
GREENBURST: A commensal Fast Radio Burst search back-end for the Green Bank Telescope
The high sensitivity of GREENBURST means that it will also be able to probe the slope of the FRB fluence distribution, which is currently uncertain in this observing band. Expand


A Machine Learning Classifier for Fast Radio Burst Detection at the VLBA
A machine learning classifier is trained and deployed that marks each candidate detection as a pulse from a known pulsar, an artifact due to radio frequency interference, or a potential new discovery within data collected by the V-FASTR fast transient system. Expand
Applying Deep Learning to Fast Radio Burst Classification
This work constructs a tree-like deep neural network (DNN) that takes multiple or individual data products as input and trains on them simultaneously and develops a hierarchical framework for ranking events by their probability of being true astrophysical transients. Expand
