Feature-Constructors {rai}

Making Source Objects

Description

These functions create and manage the features to test. The raw source only tests marginal features (the covariates in the design matrix) while the scavenger source tests for interactions between a base feature and those features already in the model. makeLocalScavenger builds on makeRawSource. Defaults are not set because these are internal functions called by rai and runAuction and all arguments are required.

Usage

makeRawSource(ncolumns)

makeLocalScavenger(theModelFeatures, name)

Arguments

ncolumns

number of features this constructor should manage, thought of as columns of the design matrix.

theModelFeatures

other features currently in the model.

name

name of the base feature with which to create interactions.

Value

A closure containing a list of functions.
