Kudos to Kaggle for hosting this project! I'm looking forward to seeing what ML practitioners come up with for classifying gravitational waveforms. Specifically, I'll be interested in something that replaces the current matched filtering signal processing process currently used to distinguish between predicted waveforms supplied by numerical relativity and observed waveforms from the gravitational wave observatories around the world.
\nBack in 2006, I spent a whole day at the LIGO Hanford observatory speaking with a staff scientist about my idea of using evolutionary algorithms for detecting binary insprials. Although they thought the idea had some merit, at the time the LIGO data sets were not available to the public. I'm pleased to see all that change with the new GW Open Science Center: https://www.gw-openscience.org/about/.
\nThe biggest issue with the gravitational strain data collected by the interferometers is determining a proper SNR due to the extreme effect various forms of noise has on the effort. Imagine trying to detect a length delta in 4km arms that amounts 1/10000 of the size of a proton! This is why Einstein believed detecting gravitational waves would never be possible.

\nWell, I think the case is already closed about Einstein being right about gravitational waves (see his original article from 1918 \"On Gravitational Waves\" and later when he would indicate he didn't think gravitational waves would ever be detected since they'd be too weak to find. A tremendous international effort, along with ingenious engineering feats in building the IFOs would lead to the first detection, GW150914. of a binary BH insprial in 2015. As a reward helping prove Einstein right, Barry Barrish, Kip Thorne, and Rainer Weiss won the 2017 Nobel Prize in Physics.
\nI've been having a blast in the past few years revisiting many of the seminal papers in GR, numerical relativity (starting with Franz Pretorius), LIGO, and LISA. It's been very challenging to get up to speed with the maths. Tensors are tough!
