🔆 October 1st 2024. We bring Zalando's AI-powered assistant to all markets and expand Trend Spotter to four new cities. I am thrilled to see the team's vision and hard work come to life. This is what happens when fashion meets AI. Read more in our press release.

AWS Data & AI Day Berlin🔆 September 19th 2024. I give a talk at AWS Data & AI Day, titled Enhancing Fashion E-Commerce with Cutting-Edge AI, Powered by AWS, hosted at the Courtyard Berlin City Center. Along with my co-presenters, Ravi Sharma and Mones Raslan from Zalando's Pricing Platform team, this invited talk highlighted some recent AI innovations at Zalando using Amazon Web Services.

🔆 May 15th 2024. Together with Nuno Castro, I give a talk titled Innovate Faster with Generative AI at the AWS Summit Berlin. (Nuno is a Senior Applied Science Manager at AWS.) In this talk, I have shared our experience utilizing generative AI models with Amazon Bedrock to improve product metadata extraction at Zalando.

Bio

Dr. Weiwei Cheng is an AI researcher with expertise in machine learning and natural language processing. After obtaining a double bachelor's degree in Computer Science and Business Administration at Zhengzhou University in June 2004, he studied Data and Knowledge Engineering at Otto von Guericke University Magdeburg from October 2005 to November 2007, where he received the Outstanding International Student Scholarship from the Ministry of Education and Cultural Affairs of Saxony-Anhalt in October 2006. He obtained his Master of Science degree with the highest honor in November 2007 and the Best Graduate of the Year award in October 2008. In December 2007, he joined the Computational Intelligence Group at Philipps University Marburg as a research staff member, where he obtained his doctorate, Dr. rer. nat., in May 2012. He joined Amazon in July 2013 and was a founding member of the Amazon Core Machine Learning team. As a senior scientist, he has led the development of AI-based products for teams such as Alexa, Search, Marketplace, Customer Reviews, and Kindle. As a Bar Raiser, he has conducted and supervised hundreds of interviews across both tech and non-tech roles. Since May 2023, Weiwei Cheng has joined Zalando as a senior principal scientist in the E-Commerce Platform organization.

Dr. Cheng has more than 50 peer-reviewed publications and holds over 10 US patents. His research won multiple accolades, including the Prominent Paper Award from the Artificial Intelligence journal, the Best Paper Award at the 21st International Conference on Case-Based Reasoning, recognition in the Notable Computing Books and Articles by ACM Computing Reviews, the Best Student Paper Award at the 19th European Conference on Machine Learning, etc. He was a recipient of the 2009 Chinese Government Award for Outstanding Self-Financed Students Abroad. His current research interests include question answering, preference learning, and multi-label classification. He was area chair at ACL and EMNLP, senior program committee member at AAAI and IJCAI.
