Winter Simulation Conference 20232023Fulfillment centers in the E-commerce industry are highly complex systems that houses inventory and fulfill customer orders. One of the key processes at these centers involves translating customer demands into trucks and yard operations. Truck yards with operational issues can create delays in customer orders. In this paper, we show how a scalable cloud-based hybrid simulation model is used to improve yard

NeurIPS 2021 Workshop on Deep Generative Models and Downstream Applications, International Journal of Forecasting – Innovations in Hierarchical Forecasting2023Hierarchical forecasting problems arise when time series have a natural group structure, and predictions at multiple levels of aggregation and disaggregation across the groups are needed. In such problems, it is often desired to satisfy the aggregation constraints in a given hierarchy, referred to as hierarchical coherence in the literature. Maintaining coherence while producing accurate forecasts can be

SIGIR 2023 Workshop on eCommerce2023Recent advancements in Natural Language Processing (NLP) have led to the development of NLP-based recommender systems that have shown superior performance. However, current models commonly treat items as mere IDs and adopt discriminative modeling, resulting in limitations of (1) fully leveraging the content information of items and the language modeling capabilities of NLP models; (2) interpreting user

SIGIR 2023 Workshop on eCommerce2023Pre-trained language models (PLM) excel at capturing semantic similarity in language, while in e-commerce, customer shopping behavior data (e.g., clicks, add-to-cart, purchases) helps establish connections between similar queries based on behavior on products. This work addressed the challenges of using sparse behavior data to build a robust query-to-query similarity prediction model and apply it to a product

IJCAI 2023 Workshop on Generalizing from Limited Resources in the Open World2023Unsupervised performance estimation, or evaluating how well models perform on unlabeled data is a difficult task. Recently, a method was proposed by Garg et al. [2022] which performs much better than previous methods. Their method relies on having a score function, satisfying certain properties, to map probability vectors outputted by the classifier to the reals, but it is an open problem which score function
