EFANNA uses a composite index to carry out ANN search, which includes an approximate kNN graph and a number of tree structures. They can be built by this library as a whole or seperately. You may build the kNN graph seperately for other use, like other graph based machine learning algorithms. Below are some demos. This project (efanna_graph) contains only the approximate nearest neighbor graph construction part in our EFANNA paper. The reasons are as follows: Some advanced graph based ANN search algorithms (e.g., HNSW, NSG) make search with Efanna almost meaningless. But the approximate kNN graph construction part in Efanna is still interesting and ...

What are Euler Path and Circuit in Graph Theory? An Euler path is a path in which each edge has been used exactly once. And, in graph theory, a path is defined as a route along the edges that start at a vertex and end at a vertex. Hence, the Euler path starts and ends at different vertices.Nearest neighbor graphs are widely used in data mining and machine learning.
