Code for this paper UMEC: Unified Model and Embedding Compression for Efficient Recommendation Systems

Jiayi Shen, Haotao Wang*, Shupeng Gui*, Jianchao Tan, Zhangyang Wang, and Ji Liu

Overview

We propose a unified model and embedding compression (UMEC) framework to hammer an efficient neural network-based recommendation system. Our framework jointly learns input feature selection and neural network compression together, and solve them as an end-to-end resource-constrained optimization problem using ADMM.

Main Results

Implementation

We perform the compression process on DLRM, which is a public recommendation model. Our proposed algorithm is mainly implemented inrc_optimizer.py and rc_utils.py. Other files are inherited from the original DLRM code repo, with several lines of modifications, such as joint_train.py, input_selection.py, and finetune.py, in order to plug in our algorithm. To run the code in this repo, you have to first follow the instructions in the original repo to download the dataset, and run the corresponding training part, to finish the data preprocessing process.

Unified Framework

To implement to joint training and compressing under the resource constraint, please see the script in script/joint_train.sh.

Input feature selection

To implement to joint training and compressing under the resource constraint, please see the script in script/input_selection.sh.

Acknowledgement

We thank the author of DLRM for providing a recommendation model benchmark.
