Teaching

As Dr. Dave Hale said: "Teaching is the best reason to be a professor at a university. The other stuff including coding and research can be done elsewhere."


Artificial Intelligence in Geosciences (人工智能地球科学)

Main instructors: Xinming Wu
Fall, 2020, open for all undergraduate students at USTC
Thanks to Huawei Cloud for granting our students free computational resources to work on their homework/final projects.
In this course, we learn the basic concepts of artificial intelligence (AI) and its applications in Geosciences. The course coves 1) mathematic fundamentals of neural networks; 2) AI software platforms (Python, Jupyter, Tensorflow/Keras, cloud computing); 3) classic machine learning classifiers; 4) basic components and principles of artificial neural networks; 5) aspects of training neural networks (e.g., loss functions, optimization methods, backpropagation, data augmentation); 6) commonly used convolutional neural networks (e.g., AlexNet, VGG, GoogLeNet, ResNet, GAN). Based on the studying of the above topics, students are expected to be able to independently design proper neural networks for their specific geoscience problems, prepare training datasets, properly train the networks, and further validate and apply the trained networks.

Xu created the final project of seismic fault segmentation challenge on the Huawei Cloud and Kaggle. In this project, we consider fault detection in seismic images as a binary segmentation problem. All the students are free to design any convolutional neural network (CNN) to achieve the fault segmentation in seismic images. We provide 2000 training dataset pairs of 2D seismic images and the corresponding binary fault labels. All the students are supported by Huawei Cloud where they can train their CNN models and make predictions on 200 validation images. All students will need to upload their prediction results to http://www.kaggle.com/c/ustc-geo-ai20 and the results (and students) will be automatically scored and ranked. Everyone is encouraged to keep updating his/her CNN model and uploading new predictions to improve the score.
Thanks to Huawei for supporting the computational sources.

Jintao created the final project of rock image classification challenge on the Kaggle. All the students are free to design any convolutional neural network (CNN) to achieve the task of rock image identification. Thanks to Xing Tan, Chang Ding and Wenkai Xuan for providing thousands of training dataset pairs of 2D rock images and the corresponding labels of 32 rock types. Our students are supported by the USTC computing resource: http://etcis-ai.ustc.edu.cn/landing to train their networks and make predictions. All students will need to upload their prediction results to https://www.kaggle.com/c/ustc-geo-ai21/ and the results (and students) will be automatically scored and ranked. Everyone is encouraged to keep updating his/her CNN model and uploading new predictions to improve the score.
