Publication number: 20240167993Abstract: A method for predicting concentration of indoor bioaerosols. The method contains the steps of providing a plurality of AI models, evaluating a prediction accuracy of each of the plurality of AI models for a venue; choosing a best model from the plurality of AI models for the venue; inputting measured data at the venue into the best model; and generating a prediction of concentration of indoor bioaerosols by the best model for the venue. To accurately monitor and predict the indoor concentration of bioaerosols, a novel methodology for predicting real-time and near-future concentration of indoor bioaerosols with artificial intelligence (AI) models is thus presented.Type: ApplicationFiled: November 22, 2022Publication date: May 23, 2024Inventors: Yik Yeung Lee, Lik Tak Ricky Chau, Yanhao Miao, Patrick Kwan Hon Lee

Patent number: 11900401Abstract: The present disclosure presents systems and related methods for creating real-time predictions. One such method comprises receiving, by a computing device, a first set of data and a second set of data, wherein the first set of data comprises a plurality of items available from a first source for a first set of users and the second set of data comprises transaction purchase data for a second set of users that have reward accounts, utilizing a predictive data model that determines a propensity score for a user from only behavior data that is not attributed to the user; receiving a third set of data from a third source comprising social media channel data for a third set of users; and updating the predictive data model to determine the propensity score for the user based at least in part on the third set of data.Type: GrantFiled: May 9, 2023Date of Patent: February 13, 2024Assignee: American Express Travel Related Services Company, Inc.Inventors: Lee Chau, Tirthankar Choudhuri, Ajay Choudhary, Vikas Grover, Mohd Arshad Naeem, Subhajit Sanyal, Dawn Thomas, Amit Jagdish Agarwal, Pranav Mehta, Kamal Gupta, Subhra Purkayastha, Prakruthi Prabhakar

Patent number: 11741483Abstract: The systems and methods described herein may be used to recommend an item to a consumer. The methods may comprise determining, based on a collaborative filtering algorithm, a consumer relevance value associated with an item, and transmitting, based on the consumer relevance value, information associated with the item to a consumer. A collaborative filtering algorithm may receive as an input at least one of: a transaction history associated with the consumer, a demographic of the consumer, a consumer profile, a type of transaction account, a transaction account associated with the consumer, a period of time that the consumer has held a transaction account, a size of wallet, a share of wallet, and/or the like.Type: GrantFiled: December 14, 2017Date of Patent: August 29, 2023Assignee: American Express Travel Related Services Company, Inc.Inventors: Lee Chau, Terrence Fischer, Anthony Mavromatis, Andrew K.

Patent number: 11710140Abstract: The systems, methods and computer program products (collectively “system”) described herein relate to customized real time data delivery. The system may be configured to receive, by a performance marketing cluster, first data from a first data source. The system may also receive, by the performance marketing cluster, second data from a second data source. The system may determine, by the marketing cluster, an analysis scheme for the first data and the second data based on the first data source. The system may also determine, by the marketing cluster, at least one of a propensity to act or a recommendation selected from a predefined number of available options for a population based on the analysis scheme and the first data source.Type: GrantFiled: January 21, 2020Date of Patent: July 25, 2023Assignee: American Express Travel Related Services Company, Inc.Inventors: Lee Chau, Tirthankar Choudhuri, Ajay Choudhary, Vikas Grover, Mohd Arshad Naeem, Subhajit Sanyal, Dawn Thomas, Amit Jagdish Agarwal, Pranav Mehta, Kamal Gupta, Subhra Purkayastha, Prakruthi Prabhakar

Patent number: 10909608Abstract: The method of processing an analysis cycle to determine interest merchants may include selecting a seed merchant relevant to a topic interest, identifying consumers that have completed a transaction with the seed merchant to generate a list of identified consumers, determining merchants visited by the identified consumers, scoring all the merchants based on network connectivity, activity, and merchant over-index, updating the seed merchant in response to the list of scored merchants relative to a scoring threshold, and scoring the list of identified consumers based on the number of distinct merchants in transaction and over-indexing. Additionally, the method may further comprise producing a list of updated interest merchants and a list of updated identified consumers, where the updated interest merchants and the updated identified consumers are relevant to the topic interest.Type: GrantFiled: December 5, 2018Date of Patent: February 2, 2021Assignee: AMERICAN EXPRESS TRAVEL RELATED SERVICES COMPANY, INCInventors: Ching-nu Chang, Lee Chau, Terrence Fischer, Anthony Harry Mavromatis

Publication number: 20200380538Abstract: At least some embodiments are directed to a system that receives data generated when point of sale terminals are used. The point of sale terminals are associated with multiple merchants. The system generates a quantitative data from the received data. The system computes a quality of service score of a first merchant based on the quantitative data. The system generates an item data structure storing values that correlate multiple users with multiple merchants at least based on the quality of service score. The system determines users that are shared by multiple merchants and computes a customer relevance value associated with the user and the first merchant. The system outputs a user-specific recommendation associated with a second merchant to a user computing device, wherein the user-specific recommendation is computed at least in part based on the customer relevance value associated with the first merchant.Type: ApplicationFiled: July 15, 2020Publication date: December 3, 2020Inventors: Lee Chau, Terrence Fischer, Anthony Mavromatis, Venkat Varadachary, Michael Wang
