Graph Lasso主要用于以下两个方面: 1.精度矩阵估计:给定一个数据集,Graph Lasso估计数据的精度矩阵,它是协方差矩阵的逆。精度矩阵描述了变量之间的关系,而且Graph Lasso的优势在于它能够推断这种关系的稀疏性。 2.图的估计:通过精度矩阵,可以构建一个图,其中节点表示变量,边表示变量之间的关系。Graph Lasso通过稀疏性...

For cis-regulatory inference using LASSO, we used hyperparameter α = 0.01, which was optimized for area under the receiver operating characteristic curves of pcHi-C and eQTL prediction. TF-target gene regulatory inference We used the SCENIC workflow76 to construct a TF-gene regulatory ...

因此,GrabCut的目标是让用户画最少的时间得到尽可能好的结果。作者还和PhotoShop中的磁力套索Magnetic Lasso在特定数据集上做了对比,结果证明只要初始的分割边缘的正确程度超过50%,那么GrabCut的结果就会优于磁力套索。 四. 应用 类似GrabCut这样的前景背景分割技术的直接应用就是”大神帮忙p个图“,我们来看看作者们列...
