%description
Efficient solvers for 10 regularized multi-task learning algorithms
applicable for regression, classification, joint feature selection, task
clustering, low-rank learning, sparse learning and network incorporation.
Based on the accelerated gradient descent method, the algorithms feature a
state-of-art computational complexity O(1/k^2). Sparse model structure is
induced by the solving the proximal operator. The detail of the package is
described in the paper of Han Cao and Emanuel Schwarz (2018)
<doi:10.1093/bioinformatics/bty831>.
