make_psi R Documentation
Generate psi function
Description
Constructs a convex combination function psi based on the sequence of solutions
obtained from the Frank-Wolfe (FW) algorithm. Each new solution theta contributes
to psi in the form 2 \cdot \text{expit}(X \theta) - 1.
Usage
make_psi(Theta)
Arguments
Theta
A numeric matrix (k x d). Each row theta is from FW inner minimization, used to recover an extremal point for convex function construction.
Value
A function psi that takes an input X and returns a numeric vector with values in the range [-1,1],
using a convex combination of past theta solutions.
