Struct GncParams 

Source 
pub struct GncParams<O: Optimizer = LevenMarquardt>
where

Expand description

Parameters for the Graduated Non-Convexity optimizer

This is a wrapper around the base optimizer parameters and the optimizer parameters for the inner optimizer. Generic over the type of the inner optimizer.

Fields§

§base: BaseOptParams

Basic parameters for GNC Optimizer

§inner: O::Params

Parameters for the inner optimizer

Will likely want to lower the max number of iterations, and increase the tolerances.

§mu_step_size: dtype

Step size for the mu parameter

This is the step size for the mu parameter. Defaults to 1.4.

§percentile: dtype

Percentile for the inlier threshold

This is the percentile for the inlier threshold. Defaults to 0.95. Will be used to compute kernel parameters for robust kernels.
