Yes, we'd like to offer a few "standard models", like BAT-C++ did. Since we can be more modular in Julia, this wouldn't necessarily have to be part of BAT.jl itself, we can do this in separate packages.
@Innerwolf on what time scale do you need this?
Hey @oschulz! Thanks for the quick reply. Great news. I wouldn't mind if you move this to another Julia package.
My timescale is not so urgent, I'm currently developing a program based on the BCMTF model from C++ and it works rather well. Right now I don't see an immediate reason or benefit from switching to the Julia version. But going into the future I might want to switch to the actively maintained version of BAT.
I would have one more question: Will using HMC be possible when using such a multi-template fitter? Or am I stuck with MHA anyway?
Will using HMC be possible when using such a multi-template fitter?
Yes, absolutely (since it'll be auto-differentiable). All samplers, including nested sampling, will work with it.
Okay I see, thanks. Feel free to resolve this issue if needed!
Let's keep it open until we actually have it implemented somewhere.
Update on this: A Julia implementation with BAT.jl interface for the upcoming HS3 standard is currently under development. HS3 covers template fits and much more..
Hey, I wanted to ask if you planned on implementing the BCMultiTemplateFitter from the C++ version. Or if there is anything similar in the Julia version. This would be very useful when fitting multiple spectral templates from simulation to experimental reference data.
