Deep RACE is a real-time reliability modeling and assessment of power semiconductor devices embedded into a wide range of smart power electronics systems. Deep RACE departures from classical learning and statistical modeling to deep learning based data analytics, combined with full system integration for scalable real-time reliability modeling and assessment. In this regard, it leverages the Long Short-Term Memory (LSTM) networks as a branch of Recurrent Neural Networks (RNN) to aggregate reliability across many power converters with similar underlying physic. Also, It offers real-time online assessment by selectively combining the aggregated training model with device-specific behaviors in the field.
First make sure you have already installed pip3, Tkinter, and git tools:
sudo apt install git python3-pip python3-tkYou should also install follwoing python packages:
sudo -H pip3 install tensorflow scipy matplotlib seabornYou only need to clone the Deep RACE repository:
git clone https://github.com/TeCSAR-UNCC/Deep_RACEChange the path to the Deep_RACE directory and run the train.py:
cd Deep_RACE
python3 ./train.pyAll the training models will be saved automatically in ./inference_models/ folder. You can load them by running inference.py file.
The ./train.py will generate and save the predition out put in a text file. The file name is based on the selected MOSFET device number. As an instance, a text file with the name of ./prediction_output/res_dev2.txt will be generated for dev#2.
You can test different devices from RoIFor5Devs.mat by altering this line in the ./train.py.
Please cite the Deep RACE if it helps your research work.
