Latest Patents

Shaoyu Zhou holds a patent for an "Optimizer with neural network estimator." This invention is a computer-operated apparatus that estimates values needed by an optimizer in a database management system (DBMS). The DBMS consists of one or more tables for storing data, each table having zero or more columns of user-definable data types and zero or more associated user-defined routines (UDRs). The apparatus features a vector extractor connected to the database tables, converting UDR inputs into a base type representation. A neural network receives the feature vector and generates estimated values for the optimizer of the DBMS. This neural network can be trained periodically using randomly generated queries or dynamically by capturing data generated during a query. During operation, the optimizer invokes the neural network to generate estimates such as selectivity and cost per call, which are essential for determining the optimum query search sequence.
