DeepStreaks: identifying fast-moving objects in the Zwicky Transient Facility data with deep learning
2019
We present DeepStreaks, a convolutional-neural-network, deep-learning system designed to efficiently identify
streakingfast-moving
near-Earth objectsthat are detected in the data of the Zwicky Transient Facility (ZTF), a wide-field, time-domain survey using a dedicated 47 sq. deg camera attached to the Samuel Oschin 48-inch Telescope at the Palomar Observatory in California, United States. The system demonstrates a 96-98% true positive rate, depending on the night, while keeping the
false positive ratebelow 1%. The sensitivity of DeepStreaks is quantified by the performance on the
testdata
setsas well as using known
near-Earth objectsobserved by ZTF. The system is deployed and adapted for usage within the ZTF Solar-System framework and has significantly reduced human involvement in the
streakidentification process, from several hours to typically under 10 minutes per day.
