Description

We introduce a novel approach for multi-task unsupervised domain adaptation. This approach is developed for bridge health monitoring using drive-by vehicle vibrations, but it can be applied to other problems, such as digit recognition, image classification, etc.

In this repository, we demonstrate our approach through two examples:

• A digit recognition example, which transfers model learned using MNIST data to MNIST-M data and conducts two tasks: odd-even classification and digits comparison.
• A drive-by bridge health monitoring example, which transfers model learned using vehicle vibration data collected from one bridge to detect, localize and quantify damage on another bridge.

Note: the drive-by bridge health monitoring experiment involves data that is not publicly available. We will work towards making the experiment replicable without violating data usage policy.

Code Usage

git clone https://github.com/jingxiaoliu/multi-task-UDA.git
cd multi-task-UDA

Run the digit recognition example with 'demo_mnist.ipynb'. Run the drive-by bridge health monitoring example with 'demo_dbbhm.ipynb'.
