Constructor Detail

NBScriptClassifier

public NBScriptClassifier(ReversePlanner planner)

Creates a new instance of NBScriptClassifier

Parameters:

planner - the reverse planner that the classifier is a part of

Method Detail

initialize

protected void initialize()

Loads the recall cases into the RecallSet and does other startup initialization

Specified by:

initialize in class ScriptClassifier

reinitialize

protected void reinitialize(int exclude)

Reloads the recall cases into the recall set and excludes a single case so that it can be tested accurately

Parameters:

exclude - case to be excluded from the updated probabilities calculation

classifyScript

protected int classifyScript(AvclMission mission,
                             VehicleCharacteristics chars)

Runs the script analyzer to determine the type of goal that corresponds to the script

Specified by:

classifyScript in class ScriptClassifier

Parameters:

mission - mission for which a characteristics array is to be generated

chars - characteristics of the vehicle for which the script is intended

Returns:

int enumeration indicating how the script is classified

characterizeScript

protected int[] characterizeScript(AvclMission mission,
                                   VehicleCharacteristics chars)

Determines characteristic values for a script mission

Parameters:

mission - mission for which a characteristics array is to be generated

chars - characteristics of the vehicle for which the script is intended

Returns:

int[] containing an array of characteristics for the script mission

closestFit

protected int closestFit(AvclMission mission,
                         VehicleCharacteristics chars)

Returns an integer enumeration for the best matching goal type for the script

Specified by:

closestFit in class ScriptClassifier

Parameters:

mission - mission for which a characteristics is to be determined

chars - characteristics of the vehicle

Returns:

int enumeration for the type of mission corresponding to the script

getConvexHull

protected GeoArea getConvexHull(List<double[]> pointList)

Generates a convex hull shell encapsulating a set of points

Parameters:

pointList - sequential list of points that the area is to contain

Returns:

GeoArea

printCharacteristics

public static void printCharacteristics(int[] charArray)

Prints a summary of the mission's characteristic values

Parameters:

charArray - array of characteristic values

main

public static void main(String[] args)

Main method included for troubleshooting only

Parameters:

args -
