Yggdrasil Decision Forests (YDF) is a production grade collection of algorithms, developed and used by Google, for the training, serving, and interpretation of Decision Forest models. YDF is open-source and is available in C++, CLI (command-line-interface), TensorFlow (under the name TensorFlow Decision Forests;TF-DF), Javascript, and Go (inference only). See the Features page for the list of features. Read Yggdrasil Decision Forests’s paper <https://arxiv.org/abs/2212.02934> for details about YDF’s design.

TensorFlow Decision Forests (TF-DF) is the official port of YDF to TensorFlow using the Keras API. TF-DF makes it easy to train and use decision forests in the TensorFlow ecosystem.
