Latest Patents

Drerup's latest patents include innovative systems that enhance online retail experiences. The first patent, titled "Counterfactual evaluation of policies for categories of items using machine learning prediction of outcomes," describes an online concierge system that fulfills orders for items offered by retailers. This system may increase the price of an item by applying a pricing policy to a category that includes the item. To optimize the application of these pricing policies, the system categorizes items and applies an outcome model to combinations of categories and pricing policies. The system then selects a set of categories and corresponding pricing policies, determining modifications to enforce constraints across multiple pricing policies.

The second patent, "Counterfactual policy evaluation of model performance," outlines an online system that uses an offline iterative clustering process to evaluate the performance of various content selection frameworks. This system clusters testing example data into sets of clusters and computes framework scores for each cluster. It also calculates improvement scores based on the performance of the clusters. If the aggregated improvement score does not meet a predetermined threshold, the system performs another iteration of the clustering process. Upon completion, it outputs the improvement scores from the most recent iteration.
