Brandon Y. Feng

I am a Ph.D. Candidate in Computer Science at the University of Maryland advised by Prof. Amitabh Varshney. My research lies at the intersection of graphics, vision, and imaging. I develop machine learning algorithms for image and 3D data processing, with applications ranging from mixed reality to natural science. My goal is to enhance our ability to perceive, represent, and create information with positive societal impact.

A Self-Adaptive Network for Multiple Sclerosis Lesion Segmentation From Multi-Contrast MRI With Various Imaging Sequences

A Self-Adaptive Network for Multiple Sclerosis Lesion Segmentation From Multi-Contrast MRI With Various Imaging Sequences

Brandon Y. Feng, Huitong Pan, Craig H. Meyer, Xue Feng

Neural networks with multimodal input disproportionately rely on certain modality while ignoring the rest. Developed a new strategy to overcome such bias and adapt to missing modalities.
