Abstract: A computer system includes a transceiver that receives over a data communications network different input data sets from one or more source computers communicating with the data communications network, where an input data set includes data objects, each data object including associated data object attributes. A processing system processes the input data sets using a predictive machine learning model to predict for a predetermined time period a list of predicted object attribute values for data objects in the input data sets. The list of predicted object attribute values is sorted to generate a current, ranked list of data objects with predicted data object attribute values, which may be modified to account for a prior ranking of data objects. A subset of lower ranked data objects from the prior ranking of data objects is replaced with a subset of higher ranked data objects from the modified, ranked list of data objects with predicted object attribute values to generate a new ranking of data objects.

Abstract: A computer system includes a transceiver that receives over a data communications network different types of input data from multiple source nodes and a processing system that defines for each of multiple data categories, a set of groups of data objects for the data category based on the different types of input data. Predictive machine learning model(s) predict a selection score for each group of data objects in the set of groups of data objects for the data category for a predetermined time period. Control machine learning model(s) determine how many data objects are permitted for each group of data objects based on the selection score. Decision-making machine learning model(s) prioritize the permitted data objects based on one or more predetermined priority criteria. Subsequent activities of the computer system are monitored to calculate performance metrics for each group of data objects and for data objects actually selected during the predetermined time period.

Abstract: A computer system includes a transceiver that receives over a data communications network different types of input data and multiple data transaction objects from multiple source nodes. A pre-processor processes the different types of input data and the data transaction objects to generate an input data structure. Based on the input data structure, one or more predictive machine learning models is trained and used to predict a probability of execution of each of the data transaction objects at a future execution time. Output data messages are then generated for transmission by the transceiver over the data communications network indicating the probability of execution for at least one of the data transaction objects at the future execution time.
