  • 15:00 - (SIRIP) Keynote 2: The Role Of GNNs In Improving Search Quality And Trust
    Karthik Subbian (Amazon, USA)
    Abstract: Featuring relevant and trustworthy items in search results is important for shoppers to accomplish their mission. The goal of featuring relevant results includes improving the discoverability of items when the search results are sparse and showing the exact matches when there are plenty of relevant items to feature. All relevant results are not trustworthy. So identifying untrustworthy results and excluding them is equally important for a good customer experience. The graph of query, ASIN, seller, buyer, and review contains important information to address the above challenges.
    In this talk, I will cover three topics on graph convolutional networks (GCN) to improve search quality and trust. First, most of our graph data is heterogenous in nature. So, we use a relational graph convolutional network (R-GCN). I will present the R-GCN approach to improve the discoverability of relevant items. Next, I will show how we can incorporate temporal dynamics in GCNs to combat abusive buyers. Combining time and graph can be non-trivial and lead to scalability challenges. Our dynamic-GCN approach incorporates temporal dynamics by iteratively learning the user and item representations at scale. Finally, I will explain how to make GCNs work in sparse settings when there is low or no neighborhood information. Our approach is truly inductive, light-weight (for production deployment), and does not require any neighborhood information during inference time.

    Bio: Karthik Subbian is a senior principal scientist at Amazon with more than 18 years of industry experience. He leads a team of scientists and engineers to improve search quality and trust. He was a research scientist and lead at Facebook, before coming to Amazon, where he had led a team of scientists and engineers to explore information propagation and user modeling problems using the social network structure and its interactions. Earlier to that, he was working at IBM T.J. Watson research center in the Business Analytics and Mathematical Sciences division. His areas of expertise include machine learning, information retrieval, and large-scale network analysis. More specifically, semi-supervised and supervised learning in networks, personalization and recommendation, information diffusion, and representation learning. He holds a masters degree from the Indian Institute of Science (IISc) and a Ph.D. from the University of Minnesota, both in computer science. Karthik has won numerous prestigious awards, including the IBM Ph.D. fellowship, best paper award at Siam Data Mining (SDM) conference 2013 and Informs Edelman laureate award 2013
