Participating universities will structure listing data to help solve a real-world ecommerce challenge.

At eBay, we containerized Jenkins to provide a continuous build infrastructure on Kubernetes Clusters to power the ecommerce marketplace experience. Our goal was to leverage the capability of Kubernetes secrets, for managing the Jenkins credentials.

eBay researchers recently published a paper about a method for KG relation embedding using dihedral group. Experimental results on benchmark KGs show that the model outperforms existing bilinear form models and even deep learning methods.

Part of our mission within Core AI at eBay is to develop computer vision models that will power innovative and compelling customer experiences. But how can we compare several visual search models and say which of them works better? This article will describe a method that is tackling this problem directly from the eyes of the users.

Learn how eBay's architecture knowledge graph was developed; the benefits eBay has received from it; and the use cases we see now and in the future for this approach.

In this article, we propose a set of better practices, designed by and for eBay ML scientists, for facilitating weaving ML modeling into the cyclical Agile process flow.

Trade has played a critical role in the history of humanity and yet, data from ecommerce, the modern form of trading, has received limited attention from academia. We at eBay want to change that.

Tips from eBay's Experimentation Science team on how you can best leverage A/B tests to measure the success and health of your product.

Incorporating knowledge graphs into recommender systems has attracted increasing attention in recent years. By exploring the interlinks within a knowledge graph, the connectivity between users and items can be discovered as paths, which provide rich and complementary information to user-item interactions. Such connectivity not only reveals the semantics of entities and relations, but also helps to comprehend a user’s interest. However, existing efforts have not fully explored this connectivity to infer user preferences, especially in terms of modeling the sequential dependencies within and holistic semantics of a path. We have developed a new model named Knowledge-aware Path Recurrent Network (KPRN) to exploit knowledge graphs for recommendation.

Interactive visual search with user feedback helps buyers find the perfect item and while enjoying the exploratory journey.

We present seven tips for visual search at scale, based on our KDD 2017 paper titled "Visual Search at eBay."
