First community-wide machine learning gravitational wave search challenge with 6 algorithms tested on progressively realistic data including real O3a noise. Top ML methods achieve 95% of matched filtering sensitivity for Gaussian noise and 70% for real noise.
Ensemble deep learning model combining multiple CNNs successfully detects all O1/O2 BBH events (except GW170818) with zero false alarms on one month of O2 data, demonstrating real-time GW analysis capability.
Extracting knowledge from high-dimensional data has been notoriously difficult, primarily due to the so-called "curse of dimensionality" and the complex joint distributions of these dimensions. This is a particularly profound issue for …
