FTRLProx_as_Matrix: Transform Data Frame to Sparse Design Matrix for...

In yanyachen/rFTRLProximal: FTRL-Proximal Algorithm

Description

Transform a data frame to sparse design matrix for FTRL-Proximal Algorithm. Please always use this function to generate sparse matrix for training and prediction.

Usage

FTRLProx_as_Matrix(data, label = NULL)

Arguments

data	a data.frame or data.table. The original data.
label	a vector containing labels.

Value

constructed dataset, an object of class "ftrl.Dataset"

Examples

library(data.table)
library(FeatureHashing)
data(ipinyou)
m.train <- FTRLProx_as_Matrix(ipinyou.train[, c("BiddingPrice", "PayingPrice"), with = FALSE],
                              label = as.numeric(ipinyou.train$IsClick))
