deepboost.default: Main function for deepboost model creation

In deepboost: Deep Boosting Ensemble Modeling

Description

Main function for deepboost model creation

Usage

deepboost.default(x, y, instance_weights = NULL, tree_depth = 5,
  num_iter = 1, beta = 0, lambda = 0.05, loss_type = "l",
  verbose = TRUE)

Arguments

x	A data.frame of samples' values
y	A data.frame of samples's labels
instance_weights	The weight of each example
tree_depth	maximum depth for a single decision tree in the model
num_iter	number of iterations = number of trees in ensemble
beta	regularisation for scores (L1)
lambda	regularisation for tree depth
loss_type	- "l" logistic, "e" exponential
verbose	- print extra data while training TRUE / FALSE

Value

A trained Deepbost model

Examples

deepboost.default(data.frame(x1=rep(c(0,0,1,1),2),x2=rep(c(0,1,0,1),2)),
 factor(rep(c(0,0,0,1),2)),num_iter=1)
deepboost.default(data.frame(x1=rep(c(0,0,1,1),2),x2=rep(c(0,1,0,1),2)),
 factor(rep(c(0,0,0,1),2)),
 num_iter=2, beta=0.1, lambda=0.00125)
