Abstract: A computerized method validates trained models in stage environments prior to deployment to production environments. A validation dataset is generated using a trained model of a first version and sampled input data as input to the trained model. The trained model of the first version is then deployed to a stage environment with the generated validation dataset. The deployed model of the first version is validated in the stage environment using the generated validation dataset and it is determined that results of the validation indicate that the trained model of the first version is invalid. Based on the invalid results, an invalidity action associated with the trained model of the first version is performed. The described method enables computationally efficient validation of accuracy and performance of trained models in stage environments, thereby reducing the likelihood that an inaccurate or underperforming model is deployed to associated production environments.

Abstract: In examples, a requestor device requests data from a data platform. A response from the data platform may include a version identifier indicating a version of data used to process the request and a device identifier indicating the server device that processed the request. Accordingly, the requestor device may include the version identifier and device identifier in a subsequent request, such that the request is routed to the server device accordingly. In examples, the server device may evaluate the version identifier to determine whether the request is associated with a different version of the data, as may occur when the data of the server device has since been updated. Similarly, the requestor device may evaluate a version identifier from the data platform as compared to that of a previously received response to determine whether the response is associated with a different version of data than that of a previous response.
