Researchers have introduced Geometric Gradient Rectification (GGR), a novel framework designed to improve open-set semi-supervised learning. GGR addresses the limitations of existing methods by focusing on gradient-level control rather than sample filtering or soft weighting. The proposed plug-in framework uses supervised gradients as an anchor and projects conflicting auxiliary gradients into an admissible space, ensuring updates are non-opposing while retaining useful signals. Experiments on CIFAR and ImageNet benchmarks demonstrate that GGR enhances baseline performance in both closed-set generalization and open-set robustness. AI
