new NearestNeighbors()

constructor Initializes a machine for finding nearest neighbors.

nearestNeighbors.getNearestNeighbors(node, desiredNeighbors) ⇒ Array

Find the specified number of nearest neighbors for the provided node.

Kind: instance method of NearestNeighbors
Returns: Array - The nearest neighbors.

Param	Type	Description
node	Object	The node to find neighbors for.
desiredNeighbors	Number	The number of neighbors to find.

nearestNeighbors.setDistancesFromNeighbors(node) ⇒ undefined

Assigns a distance from supplied node to each neighbor.

Kind: instance method of NearestNeighbors

Param	Type	Description
node	Object	The node to find neighbors for.

nearestNeighbors.getDistancesFromNeighbor(node, neighbor) ⇒ Array

Find the range adjusted distances from supplied node to a neighbor for each feature.

Kind: instance method of NearestNeighbors
Returns: Array - The distances from this node to the neighbor in each dimension.

Param	Type	Description
node	Object	The node to determine distances from.
neighbor	Node	The neighbor to determine distances from.

nearestNeighbors.classify(node, desiredNeighbors, key) ⇒ String

Classify an entity based on its neighbors.

Kind: instance method of NearestNeighbors
Returns: String - The infered classification.

Param	Type	Description
node	Object	The node to find neighbors for and classify.
desiredNeighbors	Number	The number of neighbors to find.
key	String	The key to infer a value for.
