CSIG-VIS International Lecture Series 14
    Prof. Han-Wei Shan | Machine Learning for Scientific Visualization


    Speaker: Prof. Han-Wei Shan

    Professor, The Ohio State University, USA

    Topic: Machine Learning for Scientific Visualization

    Time: Apr. 7, 2022 19:00-20:30 pm(China Standard Time)

    Abstract: In this talk, I will discuss several of our recent development on using machine learning algorithms for scientific data analysis and visualization. I will first present a neural network designed for 3D point clouds by geometric convolution, which can be extracted by clustering in the latent space, and tracked by applying tracking algorithms such as mean-shift. Then, I will describe a load-balanced particle tracing algorithm based on an online reinforcement learning paradigm, where three core components are developed to dynamically optimize parallel particle tracking performance in distributed memory systems. Additionally, I will discuss STSRNet, leveraging a deep learning model to capture the non-linear complex changes of vector field data to reconstruct high temporal resolution (HTR) and high spatial resolution (HSR) vector fields sequence from the corresponding low-resolution key frames. Finally, as a preview of our upcoming pacific vis paper (selected to publish in TVCG), GNN-Surrogate is a graph neural network-based surrogate model, making the exploration of simulation outputs on irregular grids efficient.
