Efficient Path Algorithms for Clustered Lasso and OSCAR
Atsumori Takahashi, Shunichi Nomura
In high dimensional regression, feature clustering by their effects on outcomes is often as important as feature selection. For that purpose, clustered Lasso and octagonal shrinkag…

Generalized zig-zag products of regular digraphs and bounds on their spectral expansions
Shunichi Nomura, Akimichi Takemura
We introduce a generalization of the zig-zag product of regular digraphs (directed graphs), which allows us to construct regular digraphs with m ore flexible choices of the degrees…
