Multi-task Learning for Paraphrase Generation With Keyword and Part-of-Speech Reconstruction

no code implementations Findings (ACL) 2022 Xuhang Xie, Xuesong Lu, Bei Chen

The rationale is to capture simultaneously the possible keywords of a source sentence and the relations between them to facilitate the rewriting.

GypSum: Learning Hybrid Representations for Code Summarization

1 code implementation26 Apr 2022 Yu Wang, Yu Dong, Xuesong Lu, Aoying Zhou

Current deep learning models for code summarization generally follow the principle in neural machine translation and adopt the encoder-decoder framework, where the encoder learns the semantic representations from source code and the decoder transforms the learnt representations into human-readable text that describes the functionality of code snippets.

Programming Knowledge Tracing: A Comprehensive Dataset and A New Model

no code implementations11 Dec 2021 Renyu Zhu, Dongxiang Zhang, Chengcheng Han, Ming Gao, Xuesong Lu, Weining Qian, Aoying Zhou

More specifically, we construct a bipartite graph for programming problem embedding, and design an improved pre-training model PLCodeBERT for code embedding, as well as a double-sequence RNN model with exponential decay attention for effective feature fusion.

Deep Knowledge Tracing with Learning Curves

no code implementations26 Jul 2020 Shanghui Yang, Mengxia Zhu, Xuesong Lu

The model employs three-dimensional convolutional neural networks to explicitly learn a student's recent experience on applying the same knowledge concept with that in the next question, and fuses the learnt feature with the feature representing her overall latent knowledge state obtained using a classic LSTM network.

Discovering Traveling Companions using Autoencoders

no code implementations23 Jul 2020 Xiaochang Li, Bei Chen, Xuesong Lu

The ability to discover moving objects that travel together, i. e., traveling companions, from their trajectories is desired by many applications such as intelligent transportation systems and location-based services.
