Faster Nearest Neighbor Machine Translation

Shuhe Wang, Jiwei Li, Yuxian Meng +5

NN based neural machine translation (NN-MT) has achieved state-of-the-art results in a variety of MT tasks. One significant shortcoming of NN-MT lies in its inefficiency i…

Triggerless Backdoor Attack for NLP Tasks with Clean Labels

Leilei Gan, Jiwei Li, Tianwei Zhang +6

Backdoor attacks pose a new threat to NLP models. A standard strategy to construct poisoned data in backdoor attacks is to insert triggers (e.g., rare words) into selected sentence…

Interpreting Deep Learning Models in Natural Language Processing: A Review

Xiaofei Sun, Diyi Yang, Xiaoya Li +6

Neural network models have achieved state-of-the-art performances in a wide range of natural language processing (NLP) tasks. However, a long-standing criticism against neural netw…

GNN-LM: Language Modeling based on Global Contexts via GNN

Yuxian Meng, Shi Zong, Xiaoya Li +4

Inspired by the notion that ``{\it to copy is easier than to memorize}``, in this work, we introduce GNN-LM, which extends the vanilla neural language model (LM) by allowing to ref…

OpenViDial 2.0: A Larger-Scale, Open-Domain Dialogue Generation Dataset with Visual Contexts

Shuhe Wang, Yuxian Meng, Xiaoya Li +3

In order to better simulate the real human conversation process, models need to generate dialogue utterances based on not only preceding textual contexts but also visual contexts.…

Folden: -Fold Ensemble for Out-Of-Distribution Detection

Xiaoya Li, Jiwei Li, Xiaofei Sun +5

Out-of-Distribution (OOD) detection is an important problem in natural language processing (NLP). In this work, we propose a simple yet effective framework Folden, which mimics…

Defending Against Backdoor Attacks in Natural Language Generation

Xiaofei Sun, Xiaoya Li, Yuxian Meng +4

The frustratingly fragile nature of neural network models make current natural language generation (NLG) systems prone to backdoor attacks and generate malicious sequences that cou…

Fast Nearest Neighbor Machine Translation

Yuxian Meng, Xiaoya Li, Xiayu Zheng +4

Though nearest neighbor Machine Translation (NN-MT) \citep{khandelwal2020nearest} has proved to introduce significant performance boosts over standard neural MT systems, it is p…
