Enhancing Tabular Reasoning with Pattern Exploiting Training

no code implementations21 Oct 2022 Abhilash Reddy Shankarampeta, Vivek Gupta, Shuo Zhang

Recent methods based on pre-trained language models have exhibited superior performance over tabular tasks (e. g., tabular NLI), despite showing inherent problems such as not using the right evidence and inconsistent predictions across inputs while reasoning over the tabular data.

IndicXNLI: Evaluating Multilingual Inference for Indian Languages

1 code implementation19 Apr 2022 Divyanshu Aggarwal, Vivek Gupta, Anoop Kunchukuttan

While Indic NLP has made rapid advances recently in terms of the availability of corpora and pre-trained models, benchmark datasets on standard NLU tasks are limited.

Unsupervised Contextualized Document Representation

1 code implementation EMNLP (sustainlp) 2021 Ankur Gupta, Vivek Gupta

In this paper, we address this issue by proposing SCDV+BERT(ctxd), a simple and effective unsupervised representation that combines contextualized BERT (Devlin et al., 2019) based word embedding for word sense disambiguation with SCDV soft clustering approach.

RETRONLU: Retrieval Augmented Task-Oriented Semantic Parsing

no code implementations NLP4ConvAI (ACL) 2022 Vivek Gupta, Akshat Shrivastava, Adithya Sagar, Armen Aghajanyan, Denis Savenkov

While large pre-trained language models accumulate a lot of knowledge in their parameters, it has been demonstrated that augmenting it with non-parametric retrieval-based memory has a number of benefits from accuracy improvements to data efficiency for knowledge-focused tasks, such as question answering.

Is My Model Using The Right Evidence? Systematic Probes for Examining Evidence-Based Tabular Reasoning

no code implementations2 Aug 2021 Vivek Gupta, Riyaz A. Bhat, Atreya Ghosal, Manish Shrivastava, Maneesh Singh, Vivek Srikumar

Our experiments demonstrate that a RoBERTa-based model, representative of the current state-of-the-art, fails at reasoning on the following counts: it (a) ignores relevant parts of the evidence, (b) is over-sensitive to annotation artifacts, and (c) relies on the knowledge encoded in the pre-trained language model rather than the evidence presented in its tabular inputs.

Incorporating External Knowledge to Enhance Tabular Reasoning

1 code implementation NAACL 2021 J. Neeraja, Vivek Gupta, Vivek Srikumar

Reasoning about tabular information presents unique challenges to modern NLP approaches which largely rely on pre-trained contextualized embeddings of text.

P-SIF: Document Embeddings Using Partition Averaging

1 code implementation18 May 2020 Vivek Gupta, Ankit Saw, Pegah Nokhiz, Praneeth Netrapalli, Piyush Rai, Partha Talukdar

One of the key reasons is that a longer document is likely to contain words from many different topics; hence, creating a single vector while ignoring all the topical structure is unlikely to yield an effective document representation.

INFOTABS: Inference on Tables as Semi-structured Data

no code implementations ACL 2020 Vivek Gupta, Maitrey Mehta, Pegah Nokhiz, Vivek Srikumar

In this paper, we observe that semi-structured tabulated text is ubiquitous; understanding them requires not only comprehending the meaning of text fragments, but also implicit relationships between them.

Unsupervised Document Representation using Partition Word-Vectors Averaging

no code implementations27 Sep 2018 Vivek Gupta, Ankit Kumar Saw, Partha Pratim Talukdar, Praneeth Netrapalli

One reason for this degradation is due to the fact that a longer document is likely to contain words from many different themes (or topics), and hence creating a single vector while ignoring all the thematic structure is unlikely to yield an effective representation of the document.
