Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for obtaining inventory data associated with a product or service; generating, using the inventory data, a monotonically increasing function indicative of cumulative demand; predicting future inventory events using the monotonically increasing function and a machine learning model that includes survival curve analysis; in response to predicting future inventory events using the monotonically increasing function of data and survival curve analysis, generating an instruction configured to procure one or more items of inventory; and transmitting the instruction to an inventory system.
