Code for the Density Deconvolution with Normalizing Flows paper.

Density Deconvolution with Normalizing Flows

This repository contains code for the experiments in our Density Deconvolution with Normalizing Flows adapted to astronomical data sets.

Setup

The deconv package can be installed using pip install ., or with pip install -e . if you wish to modify it.

For now you will need to use our fork of the nflows package until we can merge our changes upstream.

Experiments

Experiments used in the paper are available under experiments/flows.

TODO

1. Get this code up & running
   1. Run test cases
   2. Create jupyter notebooks with different 2D data sets
      1. Two moons
      2. Multiple donuts
2. Test how uncertainties need to be processed, answer following questions:
   1. What are the data point specific uncertainties that nflows processes?
   2. How can the Gaia specific uncertainty matrices be included into nflows?
   3. Do we trust the output?
