rEMM (version 1.0-11)

smooth_transitions: Smooths transition counts between neighboring states/clusters

Description

Each state/cluster gets the average count if all the outgoing transitions of its neighbors (i.e., clusters which are within range x its threshold).

Usage

# S4 method for EMM
smooth_transitions(x, range = 2, copy = TRUE)

Arguments

x

an object of class "EMM"

range

threshold multiplier for the smoothing range.

copy

logical; make a copy of x before reclustering? Otherwise the function will change x!

Value

smooth_transitions returns invisibly an object of class EMM. If copy=FALSE then it returns a reference to the changes object passed as x.

Examples

# NOT RUN {
data("EMMTraffic")

## learn a model
emm <- EMM(threshold=0.2, measure="eJaccard")
build(emm, EMMTraffic)

## smooth the model by adding tansitions
emm_s <- smooth_transitions(emm)

## compare graphs
op <- par(mfrow = c(1, 2), pty = "m")
plot(emm, method="MDS", main="Original")
plot(emm_s, method="MDS", main="Smoothed")
par(op)
# }
