(Bayesian) Normalizing Flow Network

A Normalizing Flow based model for Conditional Density Estimation. More info about the NFN: paper, blog post

This repo implements:

Conditional Density Estimators:

• Normalizing Flow Network (NFN)
• Mixture Density Network (MDN)
• Kernel Mixture Network (KMN)

Normalizing Flows

• Radial Flow
• Planar Flow
• Affine Flow

Installing dependencies

Tested with Python version 3.8.

pip install -r requirements.txt
pip install -e .
# Only necessary for running the evaluation scripts, not necessary for development
pip install --no-dependencies cde

Running tests

Tests are implemented using pytest

# run full test suit
pytest tests/
# run tests without the slow integration tests
pytest tests/ -m "not slow"
