In hal9001: The Scalable Highly Adaptive Lasso

A default generator for the num_knots argument for each degree of interactions and the smoothness orders.

Description

A default generator for the num_knots argument for each degree of interactions and the smoothness orders.

Usage

num_knots_generator(
  max_degree,
  smoothness_orders,
  base_num_knots_0 = 500,
  base_num_knots_1 = 200
)

Arguments

max_degree	interaction degree.
smoothness_orders	see fit_hal.
base_num_knots_0	The base number of knots for zeroth-order smoothness basis functions. The number of knots by degree interaction decays as base_num_knots_0/2^(d-1) where d is the interaction degree of the basis function.
base_num_knots_1	The base number of knots for 1 or greater order smoothness basis functions. The number of knots by degree interaction decays as base_num_knots_1/2^(d-1) where d is the interaction degree of the basis function.
