US Patent 10482394 Large-scale in-database machine learning with pure SQL

The present disclosure provides systems and methods for in-database generation of generalized linear models within a relational database. Generalized linear models form the basis of many machine learning algorithms and applications. In particular, in some implementations, the database commands that enable generation and use of the models include only pure SQL queries, thereby eliminating the need for user defined aggregates (UDAs), which are not offered by many cloud database service providers. For example, a set of client-side driver scripts can implement respective sets of pure SQL queries to import training data, generate and train the generalized linear model, and employ the model to generate inferences.
