Efficient Algorithm for Extremely Large Multi-task Regression with Massive Structured Sparsity
Seunghak Lee, Eric P. Xing
We develop a highly scalable optimization method called "hierarchical group-thresholding" for solving a multi-task regression model with complex structured sparsity constraints on…
