Edward is a Python library for probabilistic modeling, inference, and criticism. It is a testbed for fast experimentation and research with probabilistic models, ranging from classical hierarchical models on small data sets to complex deep probabilistic models on large data sets. Edward fuses three fields: Bayesian statistics and machine learning, deep learning, and probabilistic programming.
It supports modeling with
tf.layers
and Keras)It supports inference with
It supports criticism of the model and inference with
Edward is built on TensorFlow. It enables features such as computational graphs, distributed training, CPU/GPU integration, automatic differentiation, and visualization with TensorBoard.
Edward is led by Dustin Tran with guidance by David Blei. See the full list of contributors.
We are open to collaboration, and welcome researchers and developers to contribute. Check out the contributing page for how to improve Edward’s software. For broader research discussion, check out the Forum.
Edward has benefited enormously from the helpful feedback and advice of many individuals: Jaan Altosaar, Eugene Brevdo, Allison Chaney, Joshua Dillon, Matthew Hoffman, Kevin Murphy, Rajesh Ranganath, Rif Saurous, and other members of the Blei Lab, Google Brain, and Google Research.
