KDD 20212021Graph neural networks (GNNs) are powerful tools for learning from graph data and are widely used in various applications such as social network recommendation, fraud detection, and graph search. The graphs in these applications are typically large, usually containing hundreds of millions of nodes. Training GNN models on such large graphs efficiently remains a big challenge. Despite a number of sampling-based

ICML 20212021Link prediction methods are frequently applied in recommender systems, e.g., to suggest citations for academic papers or friends in social networks. However, exposure bias can arise when users are systematically underexposed to certain relevant items. For example, in citation networks, authors might be more likely to encounter papers from their own field and thus cite them preferentially. This bias can

IEEE ICIP 20212021On modern e-commerce platforms like Amazon, the number of products is fast growing, precise and efficient product classification becomes a key lever to great customer shopping experience. To tackle the large-scale product classification problem, a major challenge is how to leverage multimodal product information (e.g., image, text). One of the most successful directions is the attention-based deep multimodal

KDD 20212021We consider the problem of semantic matching in product search: given a customer query, retrieve all semantically related products from a huge catalog of size 100 million, or more. Because of large catalog spaces and real-time latency constraints, semantic matching algorithms not only desire high recall but also need to have low latency. Conventional lexical matching approaches (e.g., OkapiBM25) exploit

ACL-IJCNLP 2021 Workshop on Document-grounded Dialogue and Conversational QA2021Most prior work on task-oriented dialogue systems are restricted to limited coverage of domain APIs. However, users oftentimes have requests that are out of the scope of these APIs. This work focuses on responding to these beyond-API-coverage user turns by incorporating external, unstructured knowledge sources. Our approach works in a pipelined manner with knowledge-seeking turn detection, knowledge selection
