Abstract

The subject technology discloses configurations for creating reusable predictive models for applying to one or more data sources. The subject technology specifies a business problem to determine a probability of an event occurring. The business problem may include a constraint. A data source is selected for a predictive model associated with a predictive algorithm in which the predictive model includes one or more queries and parameters. A set of transformations are then determined based on the queries and parameters for at least a subset of data from the data source to be processed by the predictive algorithm. The subject technology identifies a set of patterns based on the set of transformations for at least the subset of data from the data source. A trained predictive model is then provided including the determined set of patterns, the set of transformations, and the associated predictive algorithm for solving the specified business problem.
