GRAM-DIFF: Gram Matrix Guided Diffusion for MIMO Channel Estimation
Xinyuan Wang, Krishna Narayanan
We propose GRAM-DIFF, a Gram-matrix-guided diffusion framework for semi-blind multiple input multiple output (MIMO) channel estimation. Recent diffusion-based estimators leverage l…
Towards reconstructing experimental sparse-view X-ray CT data with diffusion models
Nelas J. Thomsen, Xinyuan Wang, Felix Lucka +1
Diffusion-based image generators are promising priors for ill-posed inverse problems like sparse-view X-ray Computed Tomography (CT). As most studies consider synthetic data, it is…
Kimi K2.5: Visual Agentic Intelligence
Kimi Team, Tongtong Bai, Yifan Bai +333
We introduce Kimi K2.5, an open-source multimodal agentic model designed to advance general agentic intelligence. K2.5 emphasizes the joint optimization of text and vision so that…
TD-Net: A Tri-domain network for sparse-view CT reconstruction
Xinyuan Wang, Changqing Su, Bo Xiong
Sparse-view CT reconstruction, aimed at reducing X-ray radiation risks, frequently suffers from image quality degradation, manifested as noise and artifacts. Existing post-processi…
