bsnsing.default: Learn a Classification Tree with Boolean Sensing

In profyliu/bsnsing: Bsnsing: A Decision Tree Induction Method Based on Recursive Optimal Boolean Rule Composition

Learn a Classification Tree with Boolean Sensing

Description

This is the default method for bsnsing and handles binary classification only. bsnsing.formula, which calls bsnsing.default as the basic tree builder, can handle multiclass classification problems. Missing values in numeric variables are imputed as the median of the non-missing ones, and missing values in factor variables are treated as a separate level named 'NA'.

Usage

## Default S3 method:
bsnsing(x, y, controls = bscontrol(), ...)

Arguments

x	a data frame containing independent variables. Columns can be of numeric, integer, factor and logical types. The column names must be proper identifiers (e.g., must start with a letter, cannot contain special characters and spaces, etc.).
y	a vector of the response variable. The response variable can be of an integer, numeric, logical or factor type, but must have only two unique values. Typical coding of a binary response variable is 0 (for negative case) and 1 (for positive cases).
controls	an object of class bscontrol.
...	further argument to be passed to bsnsing.default.

Value

an object of class bsnsing.

Examples

## Not run: 
y <- ifelse(iris$Species == 'setosa', 1L, 0L)
x <- iris[, c('Sepal.Length', 'Sepal.Width', 'Petal.Length', 'Petal.Width')]
bs <- bsnsing(x, y, verbose = TRUE)
summary(bs)

## End(Not run)
