Title: Lightweight-Yet-Efficient: Revitalizing Ball-Tree for Point-to-Hyperplane Nearest Neighbor Search

Abstract: Finding the nearest neighbor to a hyperplane (or Point-to-Hyperplane Nearest Neighbor Search, simply P2HNNS) is a new and challenging problem with applications in many research domains. While existing state-of-the-art hashing schemes (e.g., NH and FH) are able to achieve sublinear time complexity without the assumption of the data being in a unit hypersphere, they require an asymmetric transformation, which increases the data dimension from $d$ to $\Omega(d^2)$. This leads to considerable overhead for indexing and incurs significant distortion errors.
In this paper, we investigate a tree-based approach for solving P2HNNS using the classical Ball-Tree index. Compared to hashing-based methods, tree-based methods usually require roughly linear costs for construction, and they provide different kinds of approximations with excellent flexibility. A simple branch-and-bound algorithm with a novel lower bound is first developed on Ball-Tree for performing P2HNNS. Then, a new tree structure named BC-Tree, which maintains the Ball and Cone structures in the leaf nodes of Ball-Tree, is described together with two effective strategies, i.e., point-level pruning and collaborative inner product computing. BC-Tree inherits both the low construction cost and lightweight property of Ball-Tree while providing a similar or more efficient search. Experimental results over 16 real-world data sets show that Ball-Tree and BC-Tree are around 1.1$\sim$10$\times$ faster than NH and FH, and they can reduce the index size and indexing time by about 1$\sim$3 orders of magnitudes on average. The code is available at \url.

Point to Point Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
This sample shows the Point-to-point network topology.
Network topology is the topological structure of the computer network.
Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable. Point-to-point topology is widely used in the computer networking and computer architecture.

Tree Network Topology Diagram

The Tree Network Topology Diagram examples was created using ConceptDraw DIAGRAM software with Computer and Networks solution.

Wireless Network Topology

Wireless network topology — logical topology.
Wireless network topology shows how the computers connect each other when there is no physical connection. The computers communicate each using the wireless devices.

Daisy Chain Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
A Daisy Chain is the simple computer network. It is the easiest way to add more Ethernet devices into the network. In the Daisy Chain network one computer is connected to the next without any intervening devices, thus the message is sent from one computer to the next and then to the next and so on. A Daisy Chain can be linear or ring

Grid Network Topology

The grid network topology is a type of the network topology in which the each node of the network is connected with two neighboring nodes along one or more dimensions. If the chain of nodes has the circular form and the network is one-dimensional, the topology is named the Ring. The topology with n-dimensional grid network with circularly connection of the nodes is named the Torus.

Toroidal Network Topology

This is example of the Toroidal network topology

Network topology is the topological structure of the computer network.

Complete Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
A complete (fully connected) topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are n(n-1)/2 direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the multiple paths for data that are provided by the large number of redundant links between nodes.
