Techniques are described for integrating predictive models into applications, to enable the applications to provide predictive functionality. Using the framework according to implementations, predictive models and their supporting libraries may be incorporated into applications without requiring application developers to be knowledgeable regarding the particular features of the predictive models and/or libraries. The framework exposes a common and consistent application programming interface (API) on top of the predictive libraries. Applications can use the API to interact with the predictive models, thus enabling the applications to leverage predictive functionality. Implementations also provide an API which may be used by applications to request the retraining of predictive models.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.

The method of claim 1, wherein: the first call includes one or more parameter values provided by the application; and the predictive model is executed based on the one or more parameter values. 9. A system comprising: at least one processor; and a memory communicatively coupled to the at least one processor, the memory storing instructions which, when executed, cause the at least one processor to perform operations comprising: providing a plurality of apply procedures that are each associated with a predictive model for generating predictions based on input data; receiving a first call from an application to an apply procedure and, in response, requesting that a predictive library execute a first version of the predictive model associated with the apply procedure; and providing, to the application, the predictions generated through execution of the first version of the predictive model. 10. The system of claim 9, the operations further comprising: receiving, from the application, a request to retrain the predictive model and, in response, sending an instruction to the predictive library to cause the predictive model to be retrained; and receiving an indication that the predictive model has been retrained to provide a second version of the predictive model. 11. The system of claim 10, the operations further comprising: receiving a second call from the application to the apply procedure and, in response, requesting that the predictive library execute the second version of the predictive model associated with the apply procedure; and providing, to the application, the predictions generated through execution of the second version of the predictive model. 12. The system of claim 11, wherein the first call and the second call from the application include the same set of input parameters. 13. The system of claim 9, wherein the plurality of apply procedures include one or more SQLScripts. 14. The system of claim 9, the operations further comprising: in response to receiving the first call from the application to the apply procedure, determining that the first version of the predictive model is the active version to be executed. 15. The system of claim 9, wherein the predictive library is at least one of a Predictive Analytics Library (PAL), an Automated Predictive Library (APL), or a R library. 16. The system of claim 9, wherein: the first call includes one or more parameter values provided by the application; and the predictive model is executed based on the one or more parameter values. 17. One or more computer-readable storage media storing instructions which, when executed, cause at least one processor to perform operations comprising: providing a plurality of apply procedures that are each associated with a predictive model for generating predictions based on input data; receiving a first call from an application to an apply procedure and, in response, requesting that a predictive library execute a first version of the predictive model associated with the apply procedure; and providing, to the application, the predictions generated through execution of the first version of the predictive model. 18. The one or more computer-readable storage media of claim 17, the operations further comprising: receiving, from the application, a request to retrain the predictive model and, in response, sending an instruction to the predictive library to cause the predictive model to be retrained; and receiving an indication that the predictive model has been retrained to provide a second version of the predictive model. 19. The one or more computer-readable storage media of claim 18, the operations further comprising: receiving a second call from the application to the apply procedure and, in response, requesting that the predictive library execute the second version of the predictive model associated with the apply procedure; and providing, to the application, the predictions generated through execution of the second version of the predictive model. 20.
