Struct linfa::composing::platt_scaling::Platt[−][src]

pub struct Platt<F, O> { /* fields omitted */ }

Fitted Platt model

This model contains a sigmoid scaling parameters and a second univariate, uncalibrated model. The output of the uncalibrated model is scaled with the following function:

g(x) = 1 / (1 + exp(A * f(x) + B)

The scaling factors A and B are estimated with the Newton’s method, presented in the following paper: https://www.csie.ntu.edu.tw/~cjlin/papers/plattprob.pdf

Implementations

impl<F: Float, O> Platt<F, O>[src]

pub fn params() -> PlattParams<F, O>[src]

Create default parameter set for the Platt scaling algorithm

The default values are:

  • maxiter: 100,
  • minstep: 1e-10,
  • sigma: 1e-12
