In edouardfouche/R-streamgenerator: Statistical multidimensional synthetic stream generator

Description

Generate iteratively a list of subspaces and margins based on the initial set of subspaces with a particular volatility

Usage

generate.dynamic(dim, subspaces, nstep = 10, volatility = 0.1,
  values = c(0.1, 0.2, 0.3, 0.4, 0.5, 0.8, 0.7, 0.9), cycle = 0,
  allowOverlap = FALSE)

Arguments

dim	Total number of dimensions from which to generate the subspaces.
subspaces	A list of generated subspaces.
nstep	Number of steps for which we generate new subspaces and margin values.
volatility	Percentage of subspaces to replace at each step.
values	A vector of valid values for subspace margins.
cycle	If > 0 the dynamic contains a cycle of this size.
allowOverlap	States whether overlap between subspaces are allowed. (might be a bit more complex if TRUE.). Note that full overlap and subset relation are never allowed.

Details

For each step produce a new set of (possibly overlapping) subspaces where length(subspaces)*volatility subspaces were changed and assigned a margin taken from values

Value

A list with two elements:

• marginlist A list containing lists of margins for each steps

• subspacelist A list containing lists of subspaces for each steps

Examples

subspaces <- list(c(1,2,3), c(3,4), c(5,6,7,8), c(7,8,9))
meta <- generate.dynamic(dim=20, subspaces=subspaces, nstep=3, volatility=0.5)
meta_cycle <- generate.dynamic(dim=20, subspaces=subspaces, nstep=10, volatility=0.5, cycle=3)
