Latest Patents
One of his latest patents is titled "Methods and apparatus for improving the selection of advertising." This patent describes a system and method for selecting and recommending ads based on a contextual bandit approach. The approach utilizes various embedding vectors of items, search, and page taxonomy, which are trained based on traffic data through advanced deep learning models. It employs model signals such as historical click-through rates (CTR), item price, rating, and quality from other ad placements. The learning mechanism enhances the current methodology by automatically choosing the best feature sets and adjusting model performance over time. The contextual bandit model demonstrates superior performance in terms of CTR compared to the Thompson Sampling model, achieving lower regret and faster convergence over time.
Another significant patent is "Systems and methods for safety stock settings using a parallel processing computing architecture." This disclosure outlines a graphics processing unit (GPU) programmed to generate a sample path for the demand of one or more products at a store, based on historical distribution data of demand variability. The GPU generates threads corresponding to multiple scenarios and executes them in parallel to determine parameters for each scenario. It selects parameters to minimize costs and adjusts an inventory management system accordingly.
