In RcppDynProg: 'Rcpp' Dynamic Programming

Piecewise constant fit coder factory.

Description

Build a piecewise constant fit coder with some parameters bound in.

Usage

piecewise_constant_coder(
  penalty = 1,
  min_n_to_chunk = 1000,
  min_seg = 10,
  max_k = 1000
)

Arguments

penalty	per-segment cost penalty.
min_n_to_chunk	minimum n to subdivied problem.
min_seg	positive integer, minimum segment size.
max_k	maximum segments to divide into.

Value

a vtreat coder

Examples

coder <- piecewise_constant_coder(min_seg = 1)
coder("x", 1:8, c(-1, -1, -1, -1, 1, 1, 1, 1))
