|
|
|
|
<p>A cover tree is a tree specifically designed to speed up nearest-neighbor computation in high-dimensional spaces. </p>
|
|
<p>Each non-leaf node references a point and has a nonzero number of children, including a "self-child" which references the same point. A leaf node represents only one point.</p>
|
|
<p>The tree can be thought of as a hierarchy with the root node at the top level and the leaf nodes at the bottom level. Each level in the tree has an assigned 'scale' i. The tree follows these two invariants:</p>
|
|
<ul>
|
|
<li>nesting: the level C_i is a subset of the level C_{i - 1}.</li>
|
|
<li>covering: all node in level C_{i - 1} have at least one node in the level C_i with distance less than or equal to b^i (exactly one of these is a parent of the point in level C_{i - 1}.</li>
|
|
</ul>
|
|
<p>Note that in the cover tree paper, there is a third invariant (the 'separation invariant'), but that does not apply to our implementation, because we have relaxed the invariant.</p>
|
|
<p>The value 'b' refers to the base, which is a parameter of the tree. These three properties make the cover tree very good for fast, high-dimensional nearest-neighbor search.</p>
|
|
<p>The theoretical structure of the tree contains many 'implicit' nodes which only have a "self-child" (a child referencing the same point, but at a lower scale level). This practical implementation only constructs explicit nodes – non-leaf nodes with more than one child. A leaf node has no children, and its scale level is INT_MIN.</p>

<p>Construct a child cover tree node. </p>
|
|
<p>This constructor is not meant to be used externally, but it could be used to insert another node into a tree. This procedure uses only one vector for the near set, the far set, and the used set (this is to prevent unnecessary memory allocation in recursive calls to this constructor). Therefore, the size of the near set, far set, and used set must be passed in. The near set will be entirely used up, and some of the far set may be used. The value of usedSetSize will be set to the number of points used in the construction of this node, and the value of farSetSize will be modified to reflect the number of points in the far set <em>after</em> the construction of this node.</p>
|
|
<p>If you are calling this manually, be careful that the given scale is as small as possible, or you may be creating an implicit node in your tree.</p>
