Struct opencv::ml::ParamGrid

source · [−]

pub struct ParamGrid { /* private fields */ }

Expand description

The structure represents the logarithmic grid range of statmodel parameters.

It is used for optimizing statmodel accuracy by varying model parameters, the accuracy estimate being computed by cross-validation.

Implementations

source

impl ParamGrid

source

pub fn default() -> Result<ParamGrid>

Default constructor

source

pub fn for_range(
 _min_val: f64,
 _max_val: f64,
 _log_step: f64
) -> Result<ParamGrid>

Constructor with parameters

source

pub fn create(min_val: f64, max_val: f64, logstep: f64) -> Result<Ptr<ParamGrid>>

Creates a ParamGrid Ptr that can be given to the %SVM::trainAuto method

Parameters

minVal: minimum value of the parameter grid
maxVal: maximum value of the parameter grid
logstep: Logarithmic step for iterating the statmodel parameter

C++ default parameters

min_val: 0.
max_val: 0.
logstep: 1.
