Multiple-Boundary Clustering and Prioritization to Promote Neural Network Retraining

This repository stores our experimental codes and part of the simulated datasets for paper `Multiple-Boundary Clustering and Prioritization to Promote Neural Network Retraining'. MCP is short for our proposed sampling method Multiple-Boundary Clustering and Prioritization.

Dataset:

Part of the datasets lies in the folder 'dataset'. Because some of our simulated test datasets exceed GitHub's file size limit of 100.00 MB, we can only upload part of our datasets in file '/mnist'.

The operational details of simulated test datasets are listed in the README under the folder 'dataset'.

Main experimental codes

You can easily implement our method and 5 baseline methods by yourself or modifying this code.

The main experimental codes are samedist_mnist_retrain.py, samedist_cifar_retrain.py, samedist_svhn_retrain.py. You can modify the list variables 'baselines'(methods) and 'operators'(simulated dataset) to run what you prefer.

baselines =['MCP','LSA','DSA','CES','AAL','SRS']

operators =['fgsm','jsma','bim-a','bim-b','cw-l2','scale','rotation','translation','shear','brightness','contrast']

Baseline methods

MCP. Our method "MCP" is implemented in the "samedist_***_retrain.py" as the function "select_my_optimize".

LSA/DSA. You can directly invoke the functions "fetch_lsa" and "fetch_dsa" from "/LSA_DSA/sa.py" which is downloaded online from the paper "Guiding Deep Learning System Testing Using Surprise Adequacy". These functions can help you get the SA value of each input. The higher the value of SA is, the corresponding test case is more surprise to the DNN under testing. So we select the subset of test cases with higher corresponding SAs.

CES. You can directly invoke the functions "conditional_sample" from "CES/condition.py" which is downloaded online from the git. The original codes have no external interface. In order to call these codes conveniently, we rewrite an interface function, but the internal code and logic about sampling completely reuse their code.

AAL. This approach is written by Matlab. We have write a individual README in the file "AAL" along with all the codes and our experimental setups and results. For short, you can run MATLAB programs and get the intermediate results stored in mnist_finalResults, cifar_finalResults, svhn_finalResults. Then you can run it in our python codes just as the other baseline methods.

SRS. This method is implemented in the "samedist_***_retrain.py" as the function "select_rondom".
