CG-GLORE: A Conjugate Gradient-Based Global-Local Regularization Network for Sparse-View CT Reconstruction

Aug 15, 2026

This study addresses the ill-posed inverse problem in sparse-view CT reconstruction and the poor convergence of existing deep learning methods by proposing a compact deep unfolding framework inspired by second-order optimization. By constructing a structured Hessian proxy with a conjugate gradient solver and designing a global-local regularization module that integrates convolutional features with Nyström attention, the method effectively models image priors. Experiments on AAPM and DeepLesion datasets demonstrate stable convergence, significant noise power reduction, and enhanced visual fidelity. Achieving superior quantitative metrics compared to state-of-the-art approaches, this work provides an efficient and reliable solution for sparse-view CT reconstruction.

HxAgent: Iterative Agent Planning for End-to-End Web Application Testing

Aug 15, 2026

This study addresses the challenges of autonomous agent execution and test case generation in natural language-driven web automation testing by proposing an iterative planning agent based on large language models. The proposed method innovatively integrates an active error correction strategy with a multi-source memory mechanism, effectively synthesizing short-term action feedback and long-term experiential knowledge to enable end-to-end autonomous testing. Experimental results demonstrate that the agent achieves an accuracy of 97.4% on the MiniWoB++ benchmark and 83.8% across a 350-task suite. These outcomes significantly outperform existing baselines such as WALT, validating the approach’s effectiveness in complex web interaction scenarios.
