Feature是什么?Feature就是对function的分类方法,其与function的关系就比如Role和User的关系一样. ABP中Feature具有以下属性: 其中最重要的属性是name,用以表示feature的Identity,一个feature一个name. 一个Feature可以有一组子Features,从而构成Feature树. FeatureDictionary: 其本身继承自Dictionary.其作用就是把一个Feature及其Child Features从树状结构加载…

ABP框架中存在一个Feature的特性,功能和设计思路非常类似于框架中的Authorization功能,都是来控制用户是否能够继续操作某项功能,不同点在于Authorization默认是应用在IApplicationService上控制用户或者其所属租户是否具有权限访问服务,而Feature应用更为广泛可以控制访问任意类型,但是控制方式更为单纯只有开关(Enable或者Disable),而且是无法控制具体用户的,只能是某些指定的全局范围内.注意Feature也是有父子关系的,只有父Featur…

Abstract • 从图正则数据重构方面处理无监督特征选择: • 模型的思想是所选特征不仅通过图正则保留了原始数据的局部结构,也通过线性组合重构了每个数据点: • 所以重构误差成为判断所选特征质量的自然标准. • 通过最小化重构误差,选择最好保留相似性和判别信息的特征: 1  Introduction  • 目前有两大类无监督特征选择算法:Similarity preserving 和 clustering performance maximization:Similarity preserv…
