Abstract: Methods and systems for dynamic data clustering. One of the methods includes: i) receiving a vector representing a (data) item; in response to receiving the vector: a) obtaining clusters within at least one specified metric of the vector to determine a neighborhood of clusters; b) filtering the neighborhood of clusters based at least in part on an age parameter of the clusters to determine whether there are filtered clusters; c) creating a new cluster based at least in part on the item when there are no filtered clusters; and d) storing the new cluster data for the new cluster, wherein the obtaining, filtering, creating and storing steps are performed in near real-time from receipt of the vector; ii) receiving a request for cluster data; and iii) providing cluster data including the new cluster data in response to the request.
