Overview

About

Maintained by Tong Zhang1 releasesCRAN page ↗

muscor is a package that solves a number of convex/non-convex sparse regularization formulations for regression or binary classification using multi-stage convex relaxation algorithm, described in the paper "Multi-stage Convex Relaxation for Learning with Sparse Regularization". Loss functions include least squares, logistic, truncated ls/huber. Regularization conditions include Lp + L2 (p in (0,1]), or capped-L1.

Install

R (source archive)

url <- "https://cran.r-project.org/src/contrib/Archive/muscor/muscor_0.2.tar.gz"
pkgFile <- "muscor_0.2.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.2) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
