FPCOF: FPCOF algorithm

In jaroslav-kuchar/fpmoutliers: Frequent Pattern Mining Outliers

Description

Algorithm proposed by: X. Tang, G. Li and G. Chen, "Fast Detecting Outliers over Online Data Streams," 2009 International Conference on Information Engineering and Computer Science, Wuhan, 2009, pp. 1-4.

Usage

FPCOF(data, minSupport = 0.3, mlen = 0, noCores = 1)

Arguments

data	data.frame or transactions from arules with input data
minSupport	minimum support for FPM
mlen	maximum length of frequent itemsets
noCores	number of cores for parallel computation

Value

model output (list) with all results including outlier scores

Examples

library("fpmoutliers")
dataFrame <- read.csv(
     system.file("extdata", "fp-outlier-customer-data.csv", package = "fpmoutliers"))
model <- FPCOF(dataFrame, minSupport = 0.001)
