深度学习算法在报童问题中的性能评估

Assessing the Performance of Deep Learning Algorithms for Newsvendor Problem

The University of Sydney(悉尼大学)

Yanfei Zhang, Junbin Gao

摘要:

在零售商管理中,报童问题作为基本的库存模型之一受到了广泛的关注。在解决这个问题的传统方法中,它依赖于需求的概率分布。从理论上讲,如果已知概率分布,则可以认为问题已完全解决。然而,在任何现实世界的场景中,几乎不可能甚至近似或估计需求的更好的概率分布。近年来,研究者开始采用机器学习的方法,利用其他特征信息来学习需求预测模型。在本文中,我们提出了一种监督学习,优化的需求量的产品特征信息的基础上。我们证明,原来的报童损失函数作为训练目标优于最近建议的二次损失函数。新算法已在合成数据和真实数据上进行了评估,表现出更好的性能。

英文摘要:

In retailer management, the Newsvendor problem has widely attracted attention as one of basic inventory models. In the traditional approach to solving this problem, it relies on the probability distribution of the demand. In theory, if the probability distribution is known, the problem can be considered as fully solved. However, in any real world scenario, it is almost impossible to even approximate or estimate a better probability distribution for the demand. In recent years, researchers start adopting machine learning approach to learn a demand prediction model by using other feature information. In this paper, we propose a supervised learning that optimizes the demand quantities for products based on feature information. We demonstrate that the original Newsvendor loss function as the training objective outperforms the recently suggested quadratic loss function. The new algorithm has been assessed on both the synthetic data and real-world data, demonstrating better performance.
