Scientists at the National Center for Supercomputing Applications (NCSA), located at the University of Illinois at Urbana-Champaign, have pioneered the use of GPU-accelerated deep learning for rapid detection and characterization of gravitational waves. This new approach will enable astronomers to study gravitational waves using minimal computational resources, reducing time to discovery and increasing the scientific reach of gravitational wave astrophysics. This innovative research was recently published in Physics Letters B.

Combining deep learning algorithms, numerical relativity simulations of black hole mergers—obtained with the Einstein Toolkit run on the Blue Waters supercomputer—and data from the LIGO Open Science Center, NCSA Gravity Group researchers Daniel George and Eliu Huerta produced Deep Filtering, an end-to-end time-series signal processing method. Deep Filtering achieves similar sensitivities and lower errors compared to established algorithms, while being far more computationally efficient and more resilient to noise anomalies. The method allows faster than real-time processing of in LIGO's raw data, and also enables new physics, since it can detect new classes of gravitational wave sources that may go unnoticed with existing detection algorithms. George and Huerta are extending this method to identify in real-time electromagnetic counterparts to gravitational wave events in future LSST data.

NCSA's Gravity Group leveraged NCSA resources from its Innovative Systems Laboratory, NCSA's Blue Waters supercomputer, and collaborated with talented interdisciplinary staff at the University of Illinois. Also critical to this research were the GPUs (Tesla P100 and DGX-1) provided by NVIDIA, which enabled an accelerated training of neural networks. Wolfram Research also played an important role, as the Wolfram Language was used in creating this framework for deep learning.

George and Huerta worked with NVIDIA and Wolfram researchers to create this demo to visualize the architecture of Deep Filtering, and to get insights into its neuronal activity during the detection and characterization of real gravitational wave events. This demo highlights all the components of Deep Filtering, exhibiting its detection sensitivity and computational performance.

When do we learn how to fold space? I'm getting the popcorn, sounds like great SciFi!

Where do scientists draw out knowledge and data on GV, when none of them knows what gravity is and how it arises and who provokes it.
Gravity does not have anything related to matter or energy, so GV does not exist at all. It's just amazing to me that some scientists can be so reckless and persistent that those fatamagers want to come to life and get them into a young generation, so that they too are crippled by illogical stories, of which these scientists are 100% crazed.

You all who have no idea what gravity, magnetism and matter are and how and from what they form, it would be good to try to understand it and then you can discuss these phenomena later. For you, these are "Spanish villages". And the complete science in this field has plunged deeply into anti-science because it does not know the structure of the universe, nor does it respect the Creators of everything in the MEEU, and not to mention how much they have affected their origin and origin. These "discoveries" of GV are fictions for many reasons.
One of the others is: the light travels only 130 million years and gv with that light, and exactly hit the LIGO ???

What's the origin of the creator?

Notice how your entire house of cards falls apart from the get-go?

Since gravitational waves are omnidirectionla - it'll hit everything (within its event horizon) eventually.

Or do you think the light of the sun shines only in one direction?

You all who have no idea what gravity, magnetism and matter are and how and from what they form

That's why we do science. To find out. Didn't you know that? You've been here quite a few years and you still haven't figured out what science is or what scientists do?

Man, you are slow on the uptake.

There only exist charge. It's field exist from its center to infinity. This is the texture of space we live. Immortal diametrical fields, whose center's we call charge. Empty space is only conceptual, i.e. a chosen Frame, Real, and only these! Time as Lambda makes it easier to visualize.

There is only light from each object at each instant of time many a funny measurement in distance and local fields. Motion gives us relative speed; but velocity. You know the spectrum acts like an accordion as you move in relation, big numbers, big possibilities. We exist! How do we as a complete people, peacefully share in a world where the possibility of us exist! A place, where most streams of matter coexisted. How about the hanging gardens?

@ant. al.
You want to know the origin of the Creator, you do not know anything about your origins. How did your parents not learn, at least something about it? So you are lost in "dark" matter, you have "dark" energy. you were born as a BB, you tell me that I do not know what science is, and you believe in any fabrication that tycoon science imposes to seduce torture in scientific circles. Indeed, who does not respect the Creator of everything in the universe, this is a natural forgery, which, first of all, does not possess any of the consciousness. CAN THIS LIGOTO RETURN THE RIGHT OF PHOTON OR GW? This is an unnecessary question, when neither of you nor of science knows what gravity is and how it arises, and worse, nothing is known about matter, its formation, and how it forms gravity and magnetism. If you have enough jewelry, pour out the figure of Einstein and let him be the deity, to whom you will pray that at least you will understand something in the universe.
