Causally Denoise Word Embeddings Using Half-Sibling Regression

2020 · Proceedings of the AAAI Conference on Artificial Intelligence

Distributional representations of words, also known as word vectors, have become crucial for modern natural language processing tasks due to their wide applications. Recently, a growing body of word vector postprocessing algorithm has emerged, aiming …

Unsupervised Post-Processing of Word Vectors via Conceptor Negation

2019 · Proceedings of the AAAI Conference on Artificial Intelligence

Word vectors are at the core of many natural language processing tasks. Recently, there has been interest in post-processing word vectors to enrich their semantic information. In this paper, we introduce a novel word vector …
