Implementations

impl NormalBayesClassifier

pub fn create() -> Result<Ptr<NormalBayesClassifier>>

Creates empty model Use StatModel::train to train the model after creation.

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

Loads and creates a serialized NormalBayesClassifier from a file

Use NormalBayesClassifier::save to serialize and store an NormalBayesClassifier to disk. Load the NormalBayesClassifier 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 NormalBayesClassifier
• nodeName: name of node containing the classifier

C++ default parameters

• node_name: String()

pub fn load_def(filepath: &str) -> Result<Ptr<NormalBayesClassifier>>

Loads and creates a serialized NormalBayesClassifier from a file

Use NormalBayesClassifier::save to serialize and store an NormalBayesClassifier to disk. Load the NormalBayesClassifier 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 NormalBayesClassifier
• nodeName: name of node containing the classifier

Note

This alternative version of NormalBayesClassifier::load function uses the following default values for its arguments:

• node_name: String()

Trait Implementations

impl AlgorithmTrait for NormalBayesClassifier

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

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &impl FileNodeTraitConst) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for NormalBayesClassifier

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut impl FileStorageTrait) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
