• Core codes for the paper "FGDAE: A new machinery anomaly detection method towards complex operating conditions"
• Created by Shen Yan, Haidong Shao, Zhishan Min, Jiangji Peng, Baoping Cai, Bin Liu.
• Journal: Reliability Engineering and System Safety

• Python 3.8
• pytorch 1.10.1
• and other necessary libs

• This repository provides a concise framework for machinery anomaly detection.
• It includes the pre-processing and graph composition process for the data and the model proposed in the paper.
• We have also integrated 4 baseline methods for comparison.
• Graph_train_val_test.py is the train&val&test process of our proposed method; Base_train_val_test.py is the train&val&test process of base methods.
• You need to load the data in following Datasets link at first, and put them in the data folder. Then run in General_procedure.py
• You can also adjust the structure and parameters of the model to suit your needs.

• Case1
• Case2

• General_procedure.py --data_dir "./data/Case1"; --data_num ['200Hz_0N', '300Hz_1000N', '400Hz_1400N'];
  --sensor_number 6; --fault_num 7; --unbalance_train [200, 100, 10]

• General_procedure.py --data_dir "./data/Case2"; --data_num ['G_20_0', 'G_30_2'];
  --sensor_number 8; --fault_num 5; --unbalance_train [200, 10]

• data needs loading the Datasets in above links
• datasets contians the pre-processing and graph composition process for the data
• models contians the proposed model and 4 base models
• utils contians two types of train&val&test processes
