ECML-PKDD 20212021Demand forecasting is fundamental to successful inventory planning and optimisation of logistics costs for online marketplaces such as Amazon. Millions of products and thousands of sellers are competing against each other in an online marketplace. In this paper, we propose a framework to forecast demand for a product from a particular seller (referred as offer/seller-product demand in the paper). Inventory

ECML-PKDD 20212021Amazon Last Mile strives to learn an accurate delivery point for each address by using the noisy GPS locations reported from past deliveries. Centroids and other center-finding methods do not serve well, because the noise is consistently biased. The problem calls for supervised machine learning, but how? We addressed it with a novel adaptation of learning to rank from the information retrieval domain. This

KDD 2021 WIT Workshop on Deriving Insights from User-Generated Text2021Many eCommerce catalogs rely on structured product data to provide a good experience for customers. For large scale services, product information is provided by millions of different manufacturer and vendor schemas. Due to inherent heterogeneity of this data, unifying it to a consistent catalog schema remains a challenge. Schema matching is the problem of finding such correspondences between concepts in

ICML 20212021In large-scale time series forecasting, one often encounters the situation where the temporal patterns of time series, while drifting over time, differ from one another in the same dataset. In this paper, we provably show under such heterogeneity, training a forecasting model with commonly used stochastic optimizers (e.g. SGD) potentially suffers large variance on gradient estimation, and thus incurs long-time

ESEC/FSE 20212021Integrating static analyses into continuous integration (CI) or continuous delivery (CD) has become the best practice for assuring code quality and security. Static Application Security Testing (SAST) tools fit well into CI/CD, because CI/CD allows time for deep static analyses on large code bases and prevents vulnerabilities in the early stages of the development lifecycle. In CI/CD, the SAST tools usually
