Methods

impl<'_> dyn Boost + '_

pub fn create() -> Result<PtrOfBoost>

Creates the empty model. Use StatModel::train to train the model, Algorithm::load<Boost>(filename) to load the pre-trained model.

pub fn load(filepath: &str, node_name: &str) -> Result<PtrOfBoost>

Loads and creates a serialized Boost from a file

Use Boost::save to serialize and store an RTree to disk. Load the Boost from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier

Parameters

• filepath: path to serialized Boost
• nodeName: name of node containing the classifier

C++ default parameters

• node_name: String()
