This is a lightweight repository of bayesian neural network for PyTorch.

• torch 1.2.0
• python 3.6

• pip install torchbnn or
• git clone https://github.com/Harry24k/bayesian-neural-network-pytorch

import torchbnn

• Bayesian Neural Network Regression (code): In this demo, two-layer bayesian neural network is constructed and trained on simple custom data. It shows how bayesian-neural-network works and randomness of the model.
• Bayesian Neural Network Classification (code): To classify Iris data, in this demo, two-layer bayesian neural network is constructed and trained on the Iris data. It shows how bayesian-neural-network works and randomness of the model.
• Convert to Bayesian Neural Network (code): To convert a basic neural network to a bayesian neural network, this demo shows how nonbayes_to_bayes and bayes_to_nonbayes work.
• Freeze Bayesian Neural Network (code): To freeze a bayesian neural network, which means force a bayesian neural network to output same result for same input, this demo shows the effect of freeze and unfreeze.
