[HACK] Implementing a differentiable Halo Occupation Distribution #7
Description
Implementing a differentiable Halo Occupation Distribution
This hack aims at building a TensorFlow Probability implementation of the Zheng et al. (2007) model. The goal is to have a differentiable model to populate simulations with galaxies.

Participants:
Goals and deliverable
- : Implement the Zheng et al. model in TFP
- : Sample a mock galaxy catalog from a halo catalog
- : Demonstrate variational inference of the model parameters
The deliverable is a notebook demonstrating the practicality of the method.
Resources needed
What's need is some TensorFlow knowledge, some experience with HODs, and halotools, and a lot of enthusiasm :-)
