Derivative-Free Diffusion Manifold-Constrained Gradient for Unified XAI

CVPR 2025poster

Gradient-based methods are a prototypical family of "explainability for AI" (XAI) techniques, especially for image-based models. However, they (1) require white-box access to models, (2) are vulnerable to adversarial attacks, and (3) produce attributions that lie off the image manifold, leading to e…

LLM-CXR: Instruction-Finetuned LLM for CXR Image Understanding and Generation

ICLR 2024poster

Following the impressive development of LLMs, vision-language alignment in LLMs is actively being researched to enable multimodal reasoning and visual input/output. This direction of research is particularly relevant to medical imaging because accurate medical image analysis and generation consist o…
