icp.torus.eval {ClusTorus}

Inductive prediction sets for each level

Description

icp.torus.eval evaluates whether each pre-specified evaluation point is contained in the inductive conformal prediction sets for each given level.

Usage

icp.torus.eval(icp.torus, level = 0.1, eval.point = grid.torus())

Arguments

icp.torus

an object containing all values to compute the conformity score, which will be constructed with icp.torus.

level

either a scalar or a vector, or even NULL. Default value is 0.1.

eval.point

N x N numeric matrix on [0, 2\pi)^2. Default input is grid.torus.

Value

returns a cp object with the boolean values which indicate whether each evaluation point is contained in the inductive conformal prediction sets for each given level.
