Gradient-Based Word Substitution for Obstinate Adversarial Examples Generation in Language Models

Yimu Wang, Peng Shi, Hongyang Zhang

In this paper, we study the problem of generating obstinate (over-stability) adversarial examples by word substitution in NLP, where input text is meaningfully changed but the mode…

Video-Text Retrieval by Supervised Sparse Multi-Grained Learning

Yimu Wang, Peng Shi

While recent progress in video-text retrieval has been advanced by the exploration of better representation learning, in this paper, we present a novel multi-grained sparse learnin…

Better Language Model with Hypernym Class Prediction

He Bai, Tong Wang, Alessandro Sordoni +1

Class-based language models (LMs) have been long devised to address context sparsity in -gram LMs. In this study, we revisit this approach in the context of neural LMs. We hypot…

Hierarchical Character Tagger for Short Text Spelling Error Correction

Mengyi Gao, Canran Xu, Peng Shi

State-of-the-art approaches to spelling error correction problem include Transformer-based Seq2Seq models, which require large training sets and suffer from slow inference time; an…

End-to-End Cross-Domain Text-to-SQL Semantic Parsing with Auxiliary Task

Peng Shi, Tao Yu, Patrick Ng +1

In this work, we focus on two crucial components in the cross-domain text-to-SQL semantic parsing task: schema linking and value filling. To encourage the model to learn better enc…

Segatron: Segment-Aware Transformer for Language Modeling and Understanding

He Bai, Peng Shi, Jimmy Lin +5

Transformers are powerful for sequence modeling. Nearly all state-of-the-art language models and pre-trained language models are based on the Transformer architecture. However, it…

Semantics of the Unwritten: The Effect of End of Paragraph and Sequence Tokens on Text Generation with GPT2

He Bai, Peng Shi, Jimmy Lin +5

The semantics of a text is manifested not only by what is read, but also by what is not read. In this article, we will study how the implicit "not read" information such as end-of-…
