Abstract
Incremental proximity graph maintenance (IPGM) systems and methods for online ANN search support both online vertex deletion and insertion of vertices on proximity graphs. In various embodiments, updating a proximity graph comprises receiving a workload that represents a set of vertices in the proximity graph, each vertex being associated with a type of operation such as a query, insertion, or deletion. For a query or an insertion, a search may be executed on the graph to obtain a set of top-K vertices for each vertex. In the case of a deletion, a vertex may be deleted from the proximity graph, and a local or global reconnection update method may be used to reconstruct at least a portion of the proximity graph.
