seabet sports betting platform Introduction:

With the development of big data and computing equipment，Artificial intelligence has affected every aspect of our lives。However，How to design efficient algorithms is still one of the main bottlenecks limiting the application of artificial intelligence technology。Since the data required by many artificial intelligence models are in high-dimensional geometric space，Some difficult artificial intelligence algorithm problems can be solved through computational geometry technology in high-dimensional space。In this seabet sports betting platform，We will introduce three specific examples of research in this area。（1) Density clustering algorithm DBSCAN in high-dimensional space。Clustering is one seabet sports betting platform basic methods in many large-scale data processing scenarios。DBSCseabet sports betting platformAs one seabet sports betting platform most popular density clustering algorithms，Exhibits very excellent data processing capabilities in low-dimensional space。However，Due to heavy reliance on operations such as neighbor counting，DBSCAN is difficult to apply to high-dimensional data。Our new DBSCAN algorithm can effectively break through this limitation，Gives the linear time complexity in high-dimensional space，and can be easily applied to streaming data。(2) Minimum ball coverage problem in high-dimensional space。The minimum sphere coverage problem is a basic high-dimensional geometric optimization problem，Especially has a very important connection with classification problems in machine learning。However, the traditional minimum ball coverage algorithm often requires repeated iterative reading of data，The algorithm is less efficient。Here we will introduce a novel sublinear algorithm，Significantly reduces the complexity of existing algorithms。(3) Core set construction method of data dependency。The core set is to reduce the data size、One seabet sports betting platform conventional methods to improve calculation efficiency。However, existing core set construction methods often rely on the VC dime seabet sports betting platform optimization targetnsiseabet sports betting platform, And the construction complexity is usually seabet sports betting platformgher。We will introduce a method suitable for the field of macseabet sports betting platformne learningGeneral seabet sports betting platform method of ERM model。Our method does not rely on optimization objectivesVC dimensiseabet sports betting platform, seabet sports betting platform handle dynamic updates at the same time,seabet sports betting platformtliersAnd other quesseabet sports betting platformons.
