MetaLDA: A Topic Model that Efficiently Incorporates Meta Information
2017
Besides the text content, documents and their associated words usually come with rich sets of meta information, such as categories of documents and semantic/syntactic features of words, like those encoded in word embeddings. Incorporating such …

Long-short Distance Aggregation Networks for Positive Unlabeled Graph Learning
2019
Graph neural nets are emerging tools to represent network nodes for classification. However, existing approaches typically suffer from two limitations: (1) they only aggregate information from short distance (e.g., 1-hop neighbors) each round and fail …
