Offline Reinforcement Learning for Optimizing Production Bidding Policies

no code implementations13 Oct 2023 Dmytro Korenkevych, Frank Cheng, Artsiom Balakir, Alex Nikulkov, Lingnan Gao, Zhihao Cen, Zuobing Xu, Zheqing Zhu

We use a hybrid agent architecture that combines arbitrary base policies with deep neural networks, where only the optimized base policy parameters are eventually deployed, and the neural network part is discarded after training.

Hedonic Prices and Quality Adjusted Price Indices Powered by AI

no code implementations28 Apr 2023 Patrick Bajari, Zhihao Cen, Victor Chernozhukov, Manoj Manukonda, Suhas Vijaykunar, Jin Wang, Ramon Huerta, Junbo Li, Ling Leng, George Monokroussos, Shan Wan

To accomplish this, we generate abstract product attributes, or ``features,'' from text descriptions and images using deep neural networks, and then use these attributes to estimate the hedonic price function.

Periodic-GP: Learning Periodic World with Gaussian Process Bandits

no code implementations30 May 2021 Hengrui Cai, Zhihao Cen, Ling Leng, Rui Song

We consider the sequential decision optimization on the periodic environment, that occurs in a wide variety of real-world applications when the data involves seasonality, such as the daily demand of drivers in ride-sharing and dynamic traffic patterns in transportation.
