WAE_RN: Integrating Wasserstein Autoencoder and Relational Network for Text Sequence

no code implementations CCL 2020 Xinxin Zhang, Xiaoming Liu, Guan Yang, Fangfang Li

In spite of the success of pre-trained language model in many NLP tasks, the learned text representation only contains the correlation among the words in the sentence itself and ignores the implicit relationship between arbitrary tokens in the sequence.

Coupled Item-based Matrix Factorization

no code implementations8 Apr 2014 Fangfang Li, Guandong Xu, Longbing Cao

The essence of the challenges cold start and sparsity in Recommender Systems (RS) is that the extant techniques, such as Collaborative Filtering (CF) and Matrix Factorization (MF), mainly rely on the user-item rating matrix, which sometimes is not informative enough for predicting recommendations.
