# Task-Oriented-Semantic-Communications

This is the implementation of *Intelligent task-oriented semantic communication method in artificial intelligence of things*

## Introduction of the main files
1 “ResNet18_CAM.py” is used to generate semantic importance ranking

2 “mi_estimators.py” is used to estimate mutual information

3 “MI+Classification_resnet.py” and “resnet_10_classes_channel.py” are the training code for considering and not considering mutual information between the channel input and output in the loss, respectively

4 “classification_crop.py” is used to compress semantics

5 “classification_test_resnet.py” is the test code

## Bibtex
article{liu2021sc, 
 author={C. Liu and C. Guo and Y. Yang and C. Feng and Q. Sun and J. Chen}, 
 journal={Journal on Communications}, 
 title={Intelligent task-oriented semantic communication method in artificial intelligence of things}, 
 year={2021}, 
 volume={42}, 
 number={11}, 
 page={97-108} 
 
## Notes
“resnet18-5c106cde.pth” is the inital parameters of Resnet18 which can be download online 
The proposed method can be generlized to other network structures

## P.S.
The code may look a little messy. If you have any questions, pls do not hesitate to contact me.
