Struggling with Latent GP in an inverse problem

Then, if I change omega to 50 instead of 20, the “white noise” model fits in 12 minutes to give this decent result:


while the GP model is taking a long time:

But the HSGP(m=25,c=4) has interesting results in 11 minutes, so it’s definitely worth exploring further. HSGP could be the solution to my problem:
