Biography

I am a PhD student of computer science in Johns Hopkins University. My research interests include transparent systems, medical imaging and computer vision. I have research experience about transparent deep learning systems for both 2D and 3D medical images; both radiological and pathological images; both classification and detection problems, with both PyTorch and Tensorflow.

3D scene style transfer with 2D style image by differential rendering:

  • Internship performance exceeds mentor/peers' expectation in review.
  • Learned style transfer, 3D mesh and rendering from scratch in one week.
  • Utilized PyTorch3D & nvdiffrast as differential rendering to generate 2D views.
  • Optimized texture maps by style transfer between 2D rendered images and style image.
  • Preserved object style consistency by semantic style transfer.

Symmetric learning for Fracture Detection in Pelvic Trauma X-ray:

  • Paper accepted by ECCV 2020 with poster presentation.
  • Mimicked radiologists' practice by comparing vertical asymmetric areas via Siamese network.
  • Aligned Siamese features according to GNN-detected pelvic structure landmarks.
  • Learned anatomical asymmetry explicitly by novel pixel-wise contrastive loss.

Deep Hierarchical Multi-label Classification of Chest X-ray:

  • Paper accepted by MIDL 2019 with oral presentation.
  • Special invitation to Journal ``Medical Image Analysis" and paper accepted.
  • Followed clinical taxonomy to construct hierarchical multi-label classification.
  • Developed a two-stage training procedure to fit the extreme label imbalance dataset.
  • Derived a numerically stable math formulation to avoid floating point underflow calculating loss.
