Bodi

This R package implements the Bodi algorithm. The goal of Bodi (BOosting DIversity) is to construct a sequence of learners actively promoting diversity among them. Then, increasing diversity ensures the reduction of the mean-square-error producing a strong(er) ensemble learner.

Installation

You can install the released version of Bodi from CRAN with (soon):

install.packages("Bodi")

or from Gitlab (need to make repo public or use a PAT)

remotes::install_gitlab("yannig/bodi")

Example

Bodi has a main function called boosting_diversity. This basic example shows how to obtain the Bodi fit of a simple dataset :

library(Bodi)
all <- na.omit(airquality)
smp <- sample(nrow(all), .8 * nrow(all))
boosting_diversity("Ozone", "Solar.R+Wind+Temp+Month+Day", 
                   data0 = all[smp, ], data1 = all[-smp, ])

See the documentation for further details.
