报告内容摘要
This talk presents our work on machine learning applications in inventory problems: a new product without and with replenishment opportunities. The new product may share similarities in terms of attributes/features (such as design style, season, and retail price) with some of past products, which have historical sales data. Weights can be used to measure similarities between the new product and past products, and the values of those weights are estimated by machine learning methods such as k-nearest neighbors, classification and regression tree, and random forests to the data. Then, the pair of the realized demand of a similar historical product and its associated weight and those from other similar products are utilized to approximate the expected profit and other quantities under both the newsvendor and multi-period settings. The data-based, efficient solutions are asymptotically optimal to the theoretical optimal when the number of past products becomes large. Profit Risk Constraints are also developed to overcome model misspecification and overfitting issues. Synthetical and actual data are used to verify our models and methods, demonstrating the superior performance of our method over benchmarks. [Co-authored with LIN Shaochong, David Li and Max Shen]
