Efficient Solvers for SLOPE in R, Python, Julia, and C++
Researchers have developed new software packages for R, Python, Julia, and C++ that efficiently solve the Sorted L-One Penalized Estimation (SLOPE) problem. These packages utilize a hybrid coordinate descent algorithm capable of fitting generalized linear models with various loss functions, including Gaussian, binomial, Poisson, and multinomial logistic regression. Benchmarks indicate that these new implementations outperform existing SLOPE solvers in terms of speed and memory efficiency, supporting sparse and out-of-memory matrices for flexible data handling.
