Publication number: 20250095016Abstract: This disclosure provides techniques for facilitating modeling responses to variable parameters, and in particular embodiments, within the context of a price setting strategy for a retail club. A trained member response metric model may be trained using a training corpus. A modified price for a target item may be then be predicted, and used to calculate a predicted demand for the target item. The predicted demand may be used to calculate predicted sales of the target item, after which predict a member response metric score associated with the modified price may be determined using the first trained member response metric model and the predicted sales.Type: ApplicationFiled: September 13, 2024Publication date: March 20, 2025Inventors: Pingjian Yu, Jianbo Gu, Wenyue Shi, Siddharth Hareendran, Yunus Kamal, Pawan R. Natarajan, Philippe E. Bled, Chinar Potnis

Publication number: 20240273598Abstract: There are provided systems and methods relating to checking and confirming merchandise purchased at shopping facilities. In one form, the system includes: a shopping cart containing merchandise items to be purchased; a sales transaction database; a point-of-sales system that creates transaction records identified by transaction identifiers; and a mobile device used by an employee that includes a sensor to scan a paper or digital receipt to obtain the transaction identifier and a camera to capture images of the items in the shopping cart. The system also includes a control circuit that receives the transaction identifier, accesses the database using the identifier to determine the purchased items; analyzes the images of the merchandise items in the shopping cart and creates a computer vision receipt listing detected items; compares the purchased items with the detected items; and takes an action if there is a discrepancy.Type: ApplicationFiled: April 22, 2024Publication date: August 15, 2024Inventors: Zhichun XIAO, Lingfeng ZHANG, Yao LIU, Jon HAMMER, Yutao TANG, Sicong FANG, Haining LIU, Yijing SUN, Mingquan YUAN, Shouyi ZHANG, Pingjian YU, Ryan B.

Publication number: 20230058632Abstract: Particular data is selected from a members-based dataset to provide a resultant training corpus. A first neural network receives that training corpus and generates a first trained machine learning model. That first trained machine learning model can predict member engagement score values for each of a plurality of candidate variable values. The aforementioned training corpus can also be provided to a second neural network to generate a second trained machine learning model. That second trained machine learning model can then be used to predict member engagement score values for each of a plurality of initial-state variable values. The aforementioned member engagement score values for each of the plurality of candidate variable values can then be consolidated with the member engagement score values for each of a plurality of initial-state variable values to thereby provide resultant consolidated member engagement score values.Type: ApplicationFiled: August 17, 2021Publication date: February 23, 2023Inventors: Anbu Aaron Ajay Ullas, Ehsan Nazarian, Haining Liu, Pingjian Yu, Ketan Mudda, Sara Amin, Zekun Li
