TensorFlow Decision Forests (TF-DF) is a library to train, run and interpret decision forest models (e.g., Random Forests, Gradient Boosted Trees) in TensorFlow. TF-DF supports classification, regression and ranking.

TF-DF is powered by Yggdrasil Decision Forest (YDF, a library to train and use decision forests in C++, JavaScript, CLI, and Go. TF-DF models are compatible with YDF' models, and vice versa.

Tensorflow Decision Forests is available on Linux and Mac. Windows users can use the library through WSL+Linux.

Usage example

A minimal end-to-end run looks as follows:

import tensorflow_decision_forests as tfdf
import pandas as pd

# Load the dataset in a Pandas dataframe.
train_df = pd.read_csv("project/train.csv")
test_df = pd.read_csv("project/test.csv")

# Convert the dataset into a TensorFlow dataset.
train_ds = tfdf.keras.pd_dataframe_to_tf_dataset(train_df, label="my_label")
test_ds = tfdf.keras.pd_dataframe_to_tf_dataset(test_df, label="my_label")

# Train the model
model = tfdf.keras.RandomForestModel()
model.fit(train_ds)

# Look at the model.
model.summary()

# Evaluate the model.
model.evaluate(test_ds)

# Export to a TensorFlow SavedModel.
# Note: the model is compatible with Yggdrasil Decision Forests.
model.save("project/model")
