Deep4Rec

Deep Learning based recommendation algorithms built on top of TensorFlow served on a simple API.

Documentation: https://analytics-ufcg.github.io/Deep4Rec/html/index.html

from deep4rec import datasets
from deep4rec import models

import tensorflow as tf

# Dataset
ds = datasets.build_dataset("ml-100k")

# Model
model = models.FM(ds)

model.train(
    ds,
    batch_size=128,
    epochs=200,
    loss_function="l2",
    eval_loss_functions=["rmse"],
    optimizer="adam",
)

What is Deep4Rec ?

Deep4Rec is a high level API that serves popular Deep Learning based recommendation algorithms as black box models. The models are built on top of TensorFlow >= 1.13.1 using Eager mode.

What is not Deep4Rec?

Deep4Rec is not a general purposes framework for trying new approaches and models to recommender systems.

Deep4Rec is not affiliated to the official TensorFlow project in any way.

Why Deep4Rec?

Deep4Rec was mainly developed to accelerate research by providing a way for researchers to use previously proposed models as black boxes implemented using the same framework.

Deep4Rec is also a great tool for teaching and learning Recommendation Systems methods based on Deep Learning.
