Researchers have developed a novel bilevel optimization method to learn binary sampling patterns for single-pixel imaging. This approach aims to improve reconstruction quality and acquisition speed, particularly in undersampled scenarios. The method utilizes a Straight-Through Estimator to handle the non-differentiable nature of binary optimization and incorporates learned variational regularization for enhanced robustness. Experiments on the CytoImageNet microscopy dataset demonstrated superior performance compared to existing methods, especially in low-data conditions. AI
