Hierarchical sampling procedure
WebSpecifically, several different approaches to using and scaling sampling weights in hierarchical models are promoted, yet no study has compared them to provide evidence of which method performs best and therefore should be preferred. Furthermore, different software programs implement different estimation algorithms, leading to different results. 如何利用分层聚类方法进行半监督图像分类: 对于完成 hierarchical clustering 的分层聚类结构,算法利用用户提供的一些标记的样本优化聚类的分类。其中有算法采用主动查询方式提高分类收敛速度。但是存在下面几个问题: 4. 算法是基于分层聚类结构的算法,是 bottom-up 结构,因此并不适合于大规模使用。 5. 主动学 … Ver mais 6.
