FIL.FindDensityMaxima_FixedCount

Finds local density maxima in set of values by looking for the highest concentration of a fixed number of samples.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void FindDensityMaxima_FixedCount
(
	IList<float> inValues,
	int inCount,
	bool inAllowOverlapping,
	FilNet.DataModeFunction inModeFunction,
	IList<float> outModes,
	IList<float> outSpreads
)

Parameters

Name Type Range Default Description
inValuesSystem.Collections.Generic.IList<float>Data points array.
inCountint<2, INF>3Number of points in a single window. Default value: 3.
inAllowOverlappingboolIf true all local maxima will be returned otherwise for each group of ranges that overlap a single mode will be returned (the middle of the group).
inModeFunctionFilNet.DataModeFunctionMeanMethod of calculating the center of a data mode. Default value: Mean.
outModesSystem.Collections.Generic.IList<float>Computed data modes.
outSpreadsSystem.Collections.Generic.IList<float>Spreads of windows that had a mode.

Description

Find approximations of local density maxima in a data sample by looking for highest concentrations in a window with a fixed number of samples.

Overlapping windows (i.e. a series of windows with the same count and the same spread) can be returned as a single mode (the middle those windows) if inAllowOverlapping is set to false.

inMaxSpread and inLocalBlindness can be used to further filter out potentially unnecessary points in the output.

Errors
