方法详细资料
-
listOptions
Returns an enumeration describing the available options.- 指定者:
listOptions
在接口中OptionHandler
- 返回:
- an enumeration of all the available options.
-
setOptions
Parses a given list of options.- 指定者:
setOptions
在接口中OptionHandler
- 参数:
options
- the list of options as an array of strings- 抛出:
Exception
- if an option is not supported
-
getOptions
Gets the current settings of the object.- 指定者:
getOptions
在接口中OptionHandler
- 返回:
- an array of strings suitable for passing to setOptions
-
splitNode
Splits a node into two.- 参数:
node
- The node to split.numNodesCreated
- The number of nodes that so far have been created for the tree, so that the newly created nodes are assigned correct/meaningful node numbers/ids.- 抛出:
Exception
- If there is some problem in splitting the given node.
-
setInstances
Sets the training instances on which the tree is (or is to be) built.- 参数:
inst
- The training instances.
-
setInstanceList
public void setInstanceList(int[] instList) Sets the master index array containing indices of the training instances. This array will be rearranged as the tree is built (or a node is split_), so that each node is assigned a portion in this array which contain the instances insides the node's region.- 参数:
instList
- The master index array.
-
setEuclideanDistanceFunction
Sets the distance function used to (or to be used to) build the tree.- 参数:
func
- The distance function.
-
getRevision
Returns the revision string.- 指定者:
getRevision
在接口中RevisionHandler
- 返回:
- the revision
-
