Deep Learning Enabled Semantic Communication Systems

Huiqiang Xie, Zhijin Qin, Geoffrey Ye Li, and Biing-Hwang Juang

This is the implementation of Deep learning enabled semantic communication systems.

Requirements

tensorflow-gpu==2.1.0
bert4keras==0.4.2

Preprocess

Preprocess the raw text to create the input sequences.

mkdir data
wget http://www.statmt.org/europarl/v7/europarl.tgz
tar zxvf europarl.tgz
python dataset/preprocess_text.py

Train

The train option parameters are listed below

Parameters Help
--train-snr Set the training SNR
--train-with-mine Train with the MINE model to maximize mutual information
--channel Set the training channel
--bs The training batch size
--lr Set the training learning rate
--checkpoint-path The path to save model

Example:

python main.py --bs=64 --train-snr=6 --channel=AWGN --train-with-mine --checkpoint-path=./checkpoint

Evaluation

The eval option parameters are listed below

Parameters Help
--test-snr Set the test SNR
--channel Set the test channel
--bs The training batch size
--checkpoint-path The saved model

Example:

python evaluation.py --bs=256 --test-snr=6 --channel=AWGN --checkpoint-path=./checkpoint

Notes

  • If you want to compute the sentence similarity, please download the BERT model.
