Accessors for model parameters.
Only the setter for xgboost parameters is currently implemented.
xgb.parameters(object) <- value
object |
Object of class |
value |
a list (or an object coercible to a list) with the names of parameters to set and the elements corresponding to parameter values. |
Note that the setter would usually work more efficiently for xgb.Booster.handle
than for xgb.Booster, since only just a handle would need to be copied.
data(agaricus.train, package='xgboost')
train <- agaricus.train
bst <- xgboost(data = train$data, label = train$label, max_depth = 2,
eta = 1, nthread = 2, nrounds = 2, objective = "binary:logistic")
xgb.parameters(bst) <- list(eta = 0.1)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
