ide: Intrinsic Dimension Estimation

In kjohnsson/intrinsicDimension: Intrinsic Dimension Estimation

Description

Intrinsic dimension estimation with method given as parameter.

Usage

localIntrinsicDimension(.data, .method, ...)
globalIntrinsicDimension(.data, .method, ...)
pointwiseIntrinsicDimension(.data, .method, ...)

Arguments

.data	Data set for which dimension should be estimated.
.method	For local.dimension.estimation, one of 'essLocalDimEst', 'dancoDimEst', 'pcaLocalDimEst', 'maxLikLocalDimEst', 'knnDimEst'. For global.dimension.estimation, one of 'dancoDimEst', 'maxLikGlobalDimEst', 'knnDimEst'. For pointwise.dimension.estimation, 'pcaOtpmLocalDimEst' or 'maxLikPointwiseDimEst'.
...	arguments passed to intrinsic dimension estimator.

Details

For the localIntrinsicDimension function, .data should be a local data set, i.e. a piece of a data set that is well approximated by a hyperplane (meaning that the curvature should be low in the local data set).

The function pointwiseIntrinsicDimension estimates local dimension around each data point in the data set.

Value

For localIntrinsicDimension and globalIntrinsicDimension, a DimEst object with the slot dim.est containing the dimension estimate and possibly additional slots containing additional information about the estimation process. For pointwiseIntrinsicDimension, a DimEstPointwise object, inheriting data.frame, with one slot dim.est containing the dimension estimates and possibly additional slots containing additional information about the estimation process.
