Deep Learning based Data Representation
Computation resources such as node-hours, storage space, memory, and bandwidth are often limited in supply for scientific computing, which pushes scientists and researchers to develop new strategies to perform the desired tasks quicker and use a smaller storage footprint. At GRAVITY lab, we have proposed various tools and techniques to reduce computation resources. For example, using a neural network based hierarchical super-resolution algorithm to upscale low-resolution data, or transform data in a more compact latent space for importance-driven scientific data explorations as well as to reduce data that are not deemed important. We have also proposed a particle latent representation method for efficient feature analysis and tracking.
