liquidSVM is a package written in C++ that provides SVM-type solvers for various classification and regression tasks. Because of a fully integrated hyper-parameter selection, very carefully implemented solvers, multi-threading and GPU support, and several built-in data decomposition strategies it provides unprecedented speed for small training sizes as well as for data sets of tens of millions of samples.
You can use it e.g. for multi-class classification, least squares (kernel) regression, or even quantile regression, etc.:
install.packages("liquidSVM")
library(liquidSVM)
model <- mcSVM(Species ~ ., iris)
predict(model, iris)
model <- lsSVM(Height ~ ., trees)
y <- predict(model, trees)
model <- svmQuantileRegression(Height ~ ., trees)
y <- test(model, trees)If you install build the package to be used on several machines please use the following:
