Part II/Part III/MPhil Project Supervision

I am supervising Part II, Part III, and MPhil projects. The students are welcome to contact me to discuss their project ideas. I am interested in broad topics across machine learning (especially computer vision) and artificial intelligence. My current research focuses on computer vision, particularly 2D and 3D reconstruction and manipulation. I am also open to discussing other ideas. Please also include your transcript and CV (if you have one) when contacting me.

Some potential project ideas (suggestions of your own are more than welcome):

• CLIP-related: see here
• Application of frequency rectification techniques used in FrePolad on other 3D representations (see here) or images (see here).
• 3D generation/manipulation
  • Joint generation of 3D scene and human motions with mutual spatial awareness: see here
  • Combine text-driven scene generation and object generation
  • Iterative editing of 3D objects
  • Text-guided SMPL (a parametrized human model) manipulation
• (Text-driven) 3D vision tasks (e.g., detection/recognition/captioning/classification/segmentation) via rendering to 2D
• A thorough comparison/analysis/summary of the pros & cons of the diffusion model and GAN
• Prompt engineering: analyze prompts to language models (e.g., ChatGPT or text-to-image models) that can 1. facilitate the original task, 2. achieve a certain type of attack (e.g., acquire some private information), or 3. improve the model to defend itself from this attack
• Stock prediction model
• Neural BRDF models (machine learning + graphics)
