fm.generate_fm_kadditive_convex_sparse: Generate kadditive convex sparse fuzzy measures

In Rfmtool: Fuzzy Measure Tools

Generate kadditive convex sparse fuzzy measures

Description

Generates a random k-additive Belief fuzzy measure in sparse representation

Usage

  fm.generate_fm_kadditive_convex_sparse(n, kadd, nonzero, envsp = NULL)

Arguments

n	Inputs length. (n inputs)
kadd	kadd is the value of k-additivity, which is used for reducing the complexity of fuzzy measures. default value is kadd = n. 1 < kadd < n+1; if kdd=n - f.m. is unrestricted
nonzero	Values stored and indexed in the respective arrays which are part of the structure
envsp	Structure required for sparse representation which stores the relevant values (k-tuples). It is obtained from fm.PrepareSparseFM(n).

Value

output

The output is k-additive Belief fuzzy measure in sparse representation
