Fused Lasso for Feature Selection using Structural Information [article]

Lu Bai, Lixin Cui, Yue Wang, Philip S. Yu, Edwin R. Hancock
2019 arXiv   pre-print
However, most state-of-the-art methods tend to overlook the structural correlation information between pairwise samples, which may encapsulate useful information for refining the performance of feature  ...  To overcome these issues, we propose a new feature selection method using structural correlation between pairwise samples.  ...  Therefore, we unify the minimization problem of fused lasso and Eq.(5) and propose the so called fused lasso for feature selection using structural information(InFusedLasso), which is mathematically formulated  ...
