Mutable methods for crate::ml::Boost

Required Methods§

Source

fn as_raw_mut_Boost(&mut self) -> *mut c_void

Provided Methods§

Source

fn set_boost_type(&mut self, val: i32) -> Result<()>

Type of the boosting algorithm. See Boost::Types. Default value is Boost::REAL.

§See also

setBoostType getBoostType

Source

fn set_weak_count(&mut self, val: i32) -> Result<()>

The number of weak classifiers. Default value is 100.

§See also

setWeakCount getWeakCount

Source

fn set_weight_trim_rate(&mut self, val: f64) -> Result<()>

A threshold between 0 and 1 used to save computational time. Samples with summary weight $inline formula$ do not participate in the next iteration of training. Set this parameter to 0 to turn off this functionality. Default value is 0.95.
