Latest Patents

One of his latest patents is titled "Demand forecasting using weighted mixed machine learning models." This invention focuses on forecasting demand for an item by utilizing historical sales data across various time periods. It incorporates multiple features that define one or more feature sets, which serve as inputs to different algorithms to generate various models. Each model is trained to produce past demand forecasts, and a root-mean-square error (RMSE) is determined for each forecast. Based on the RMSE, weights are assigned to each model, leading to a final demand forecast for future time periods.

Another significant patent is "Dynamic feature selection for model generation." This invention aims to create a model of product demand that includes an optimized feature set. It involves receiving sales history and relevant features for a product, designating mandatory features, and forming training and validation datasets. By randomly selecting optional features, the invention generates a feature test set, which is used to train an algorithm. The optimized feature set is determined when an early stopping metric falls below a predefined threshold.
