HybridBackend

HybridBackend is a high-performance framework for training wide-and-deep recommender systems on heterogeneous cluster.

Features

• Memory-efficient loading of categorical data
• GPU-efficient orchestration of embedding layers
• Communication-efficient training and evaluation at scale
• Easy to use with existing AI workflows

Usage

A minimal example:

import tensorflow as tf
import hybridbackend.tensorflow as hb

ds = hb.data.Dataset.from_parquet(filenames)
ds = ds.batch(batch_size)
# ...

with tf.device('/gpu:0'):
  embs = tf.nn.embedding_lookup_sparse(weights, input_ids)
  # ...

Please see documentation for more information.
