Above-the-Fold Loading 加载机制在 Spartacus Storefront 里的应用
Angular 应用默认情况下，Component 组件总是被积极渲染，不管组件是否在用户的 viewports 中。 这可能对性能带来负面影响，但可以通过评估视口与组件来进行优化—— View ports 内（或附近）的所有组件都应该加载，其他组件可以延迟。 作为延迟加载的一个积极的副产物，我们将 ......

Learning Action Completeness from Points for Weakly-supervised Temporal Action Localization概述
1.针对的问题 在弱监督时序动作定位领域提出了一些帧监督的方法，但是由于标签稀疏性，现有的工作无法学习动作的完整性，动作预测零碎，导致在高IoU阈值的情况下表现较差。作者试图通过生成密集的伪标签，为模型提供完整性指导。 2.主要贡献 •引入了一个新的框架，其中生成了密集的最优序列，以在点监督设置下为 ......
