Enhanced Sentence Alignment Network for Efficient Short Text Matching

no code implementations EMNLP (WNUT) 2020 Zhe Hu, Zuohui Fu, Cheng Peng, Weiwei Wang

Cross-sentence attention has been widely applied in text matching, in which model learns the aligned information between two intermediate sequence representations to capture their semantic relationship.

Deep Structure and Attention Aware Subspace Clustering

1 code implementation25 Dec 2023 Wenhao Wu, Weiwei Wang, Shengjiang Kong

However, previous deep clustering methods, especially image clustering, focus on the features of the data itself and ignore the relationship between the data, which is crucial for clustering.
