ideas for speeding up sampling galaxy properties

[ismael-mendoza]

Current best timing is ~ 0.5 sec per object with ~1000 chains.

Ideas:

• NUTS initialization
• SBI (or just SBI)
• Barker (explore timing and sample efficiency with barker proposal  #1)
• CHEES-MC (explore timing and sample efficiency with chees-hmc #2)
• Generalized HMC (paper)
• MCLMC (https://blackjax-devs.github.io/sampling-book/algorithms/mclmc.html)
• FlowMC (https://github.com/kazewong/flowMC)
• SMC: https://blackjax-devs.github.io/sampling-book/algorithms/TemperedSMC.html#tempered-smc-with-hmc-kernel
