研究人员推出了一种名为 FlexiGrad 的新型无参数方法，旨在改进分层细粒度分类任务。该技术解决了由于应用于共享模型骨干的粗粒度和细粒度分类器产生的冲突梯度而导致的训练不稳定问题。通过选择性地去除有害的梯度分量并加强共享方向，FlexiGrad 实现了更稳定的优化，并能更好地保留全局结构和细粒度细节。该方法在 CUB-200-2011、FGVC-Aircraft 和 Stanford Cars 等基准数据集上展示了更高的准确性，并能无缝集成到现有架构中。 AI

Many fine-grained recognition tasks contain hierarchical labels such as order, family and species. Although this supervision should be beneficial, jointly optimising all levels often leads to unstable training because coarse and fine classifiers impose inconsistent gradients on t…
