dann.data.frame: Discriminant Adaptive Nearest Neighbor Classification

In dann: Discriminant Adaptive Nearest Neighbor Classification

Discriminant Adaptive Nearest Neighbor Classification

Description

Discriminant Adaptive Nearest Neighbor Classification

Usage

## S3 method for class 'data.frame'
dann(
  x,
  y,
  k = 5,
  neighborhood_size = max(floor(nrow(x)/5), 50),
  epsilon = 1,
  ...
)

Arguments

x	A data frame.
y	A vector.
k	The number of data points used for final classification.
neighborhood_size	The number of data points used to calculate between and within class covariance.
epsilon	Diagonal elements of a diagonal matrix. 1 is the identity matrix.
...	Additional parameters passed to methods.

Details

This is an implementation of Hastie and Tibshirani's Discriminant Adaptive Nearest Neighbor Classification publication..

Value

An S3 class of type dann.

Examples

library(dann)
library(mlbench)
library(magrittr)
library(dplyr)

set.seed(1)
train <- mlbench.circle(300, 2) %>%
  tibble::as_tibble()
colnames(train) <- c("X1", "X2", "Y")
y <- train$Y
x <- train[, 1:2]

dann(x, y)
