About Me

Hi, I’m Benteng Sun (SMARK, ε­™ε₯”θ…Ύ).

I’m an undergraduate student in Data Science (Mathematics Category) at Harbin Institute of Technology, Shenzhen (graduating in 2026). My research centers on machine learning, sparse representation, and computational imaging, advised by Prof. Yongyong Chen.

I have published at ICLR and participated in top-tier competitions. Currently, I am exploring efficient and controllable generation paradigms, aiming to build scalable frameworks for images, videos, and 3D content.

Feel free to reach out at SMARK2019@outlook.com.

Research Interests

My research bridges theoretical modelling and practical algorithm design, currently focusing on:

  • Multimodal Understanding & Generation β€” cross-modal synthesis, language-guided visual generation, modality fusion

  • Generative Modeling and Controllable Generation β€” structure-guided diffusion, efficient sampling, scalable 2D/3D/video frameworks

  • Computational Imaging & Low-Level Vision β€” spectral imaging, MRI acceleration, physics-driven restoration, compressed sensing

I am particularly interested in advancing new generation paradigms that integrate multimodal understanding, sparse structures, and efficient computation across 2D, 3D, and video modalities.
