Using AI for Gravitational Wave Generation

Click For Summary

Discussion Overview

The discussion revolves around the potential use of artificial intelligence (AI), specifically deep neural networks, for generating gravitational wave (GW) waveforms. Participants explore the feasibility of AI in this context, contrasting it with existing methods and applications in other fields, such as particle physics simulations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks papers that specifically address the use of AI for generating gravitational waveforms, noting the existing literature primarily focuses on data analysis.
  • Another participant expresses skepticism about AI's ability to create new waveforms, suggesting that it may overfit to training data and could be more useful in selecting the best waveform from existing options.
  • A participant counters the skepticism by referencing successful applications of AI in particle physics simulations, arguing that AI can interpolate among existing simulations to create new event topologies, implying similar potential for gravitational waves.
  • There is acknowledgment that while algorithms already generate waveforms, the integration of machine learning techniques is still developing, and the potential for mainstream application remains uncertain.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the effectiveness of AI in generating new gravitational waveforms. While some express doubt about its utility, others advocate for its potential based on analogous successes in other fields. The discussion remains unresolved with competing views on the applicability of AI in this context.

Contextual Notes

Participants reference existing algorithms for waveform generation and the limitations of current machine learning techniques in this area. There is also a noted lack of development on the techniques discussed in the referenced paper.

Hello! Can someone point me towards some papers that use AI for gravitational wave generation? I found many papers using AI to analyze data, but not really something where AI is used to actually generate waveforms. For example this was done for particle physics simulations to increase the speed by a few orders of magnitude (at some loss in accuracy), so given that a GW simulation takes a few weeks (based on SXS data), I assume this would be a good place to try AI simulations (I know there are some non-AI based codes out there providing simulations, but I am interested in codes using AI). By AI I mean deep neural networks.

I don't see how AI would be helpful in creating NEW waveforms as I believe it would most likely overfit to whatever data you train it on? So, maybe you could use AI to help decide which waveform would be best given a bunch of them (outside of what is being used right now, since ML is being used in GW stuff).

The closest paper that I know of that would do this would be: https://arxiv.org/pdf/1909.10986.pdf
It might be a good place to start, but I don't think AI/Machine Learning can really do what you ask, but I've only dabbled in it.

I will look over that paper, but AI can certainly do that. As I said there are lots of papers used for particle physics simulations (jets for example at LHC using GANs) and obviously they are not just reproducing already existing simulations, but interpolating among them and hence creating new event topologies much faster. So I see no reason why this can't be done for GW.

I'm not sure about particle physics simulations because that isn't my field, so I'd have to see if there are any similarities.

Waveforms are already generated via algorithms for the most (as stated in the paper), and yes, i was being dramatic that ML can't be used, but at the current point, I see no reason why it'd be mainstream. They do talk about using machine learning for it in the paper as well, but I haven't seen any development on the techniques, but hopefully that paper sets you off in the right direction!

Good luck.
