[−][src]Struct opencv::ml::ParamGrid
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
impl ParamGrid[src]
pub fn as_raw_ParamGrid(&self) -> *const c_void[src]
pub fn as_raw_mut_ParamGrid(&mut self) -> *mut c_void[src]
impl ParamGrid[src]
pub fn default() -> Result<ParamGrid>[src]
Default constructor
pub fn for_range(
_min_val: f64,
_max_val: f64,
_log_step: f64
) -> Result<ParamGrid>[src]
_min_val: f64,
_max_val: f64,
_log_step: f64
) -> Result<ParamGrid>
Constructor with parameters
pub fn create(
min_val: f64,
max_val: f64,
logstep: f64
) -> Result<Ptr<ParamGrid>>[src]
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.
