Recommendation Model

Overview

This is an implementation of WideDeep as described in the Wide & Deep Learning for Recommender System paper.

WideDeep model jointly trained wide linear models and deep neural network, which combined the benefits of memorization and generalization for recommender systems.

Requirements

• Install MindSpore.

• Download the dataset and convert the dataset to mindrecord, command as follows:

python src/preprocess_data.py

Arguments:

• --data_path: Dataset storage path (Default: ./criteo_data/).

Dataset

The Criteo datasets are used for model training and evaluation.

Train and evaluate model

To train and evaluate the model, command as follows:

python train_and_eval.py

Arguments:

• --device_target: Device where the code will be implemented (Default: Ascend).
• --data_path: This should be set to the same directory given to the data_download's data_dir argument.
• --epochs: Total train epochs.
• --batch_size: Training batch size.
• --eval_batch_size: Eval batch size.
• --field_size: The number of features.
• --vocab_size： The total features of dataset.
• --emb_dim： The dense embedding dimension of sparse feature.
• --deep_layers_dim： The dimension of all deep layers.
• --deep_layers_act： The activation of all deep layers.
• --dropout_flag： Whether do dropout.
• --keep_prob： The rate to keep in dropout layer.
• --ckpt_path：The location of the checkpoint file.
• --eval_file_name : Eval output file.
• --loss_file_name : Loss output file.

To train the model in one device, command as follows:

python train.py

Arguments:

• --device_target: Device where the code will be implemented (Default: Ascend).
• --data_path: This should be set to the same directory given to the data_download's data_dir argument.
• --epochs: Total train epochs.
• --batch_size: Training batch size.
• --eval_batch_size: Eval batch size.
• --field_size: The number of features.
• --vocab_size： The total features of dataset.
• --emb_dim： The dense embedding dimension of sparse feature.
• --deep_layers_dim： The dimension of all deep layers.
• --deep_layers_act： The activation of all deep layers.
• --dropout_flag： Whether do dropout.
• --keep_prob： The rate to keep in dropout layer.
• --ckpt_path：The location of the checkpoint file.
• --eval_file_name : Eval output file.
• --loss_file_name : Loss output file.

To train the model in distributed, command as follows:

# configure environment path before training
bash run_multinpu_train.sh RANK_SIZE EPOCHS DATASET RANK_TABLE_FILE 

# configure environment path before training
bash run_auto_parallel_train.sh RANK_SIZE EPOCHS DATASET RANK_TABLE_FILE 

To evaluate the model, command as follows:

python eval.py

Arguments:

• --device_target: Device where the code will be implemented (Default: Ascend).
• --data_path: This should be set to the same directory given to the data_download's data_dir argument.
• --epochs: Total train epochs.
• --batch_size: Training batch size.
• --eval_batch_size: Eval batch size.
• --field_size: The number of features.
• --vocab_size： The total features of dataset.
• --emb_dim： The dense embedding dimension of sparse feature.
• --deep_layers_dim： The dimension of all deep layers.
• --deep_layers_act： The activation of all deep layers.
• --keep_prob： The rate to keep in dropout layer.
• --ckpt_path：The location of the checkpoint file.
