Answer-level Calibration for Free-form Multiple Choice Question Answering

1 code implementation ACL 2022 Sawan Kumar

We present ALC (Answer-Level Calibration), where our main suggestion is to model context-independent biases in terms of the probability of a choice without the associated context and to subsequently remove it using an unsupervised estimate of similarity with the full context.

Interpreting Text Classifiers by Learning Context-sensitive Influence of Words

no code implementations NAACL (TrustNLP) 2021 Sawan Kumar, Kalpit Dixit, Kashif Shah

Many existing approaches for interpreting text classification models focus on providing importance scores for parts of the input text, such as words, but without a way to test or improve the interpretation method itself.

Reordering Examples Helps during Priming-based Few-Shot Learning

1 code implementation Findings (ACL) 2021 Sawan Kumar, Partha Talukdar

Finally, we analyze the learned prompts to reveal novel insights, including the idea that two training examples in the right order alone can provide competitive performance for sentiment classification and natural language inference.

NILE : Natural Language Inference with Faithful Natural Language Explanations

1 code implementation ACL 2020 Sawan Kumar, Partha Talukdar

In this work, we focus on the task of natural language inference (NLI) and address the following question: can we build NLI systems which produce labels with high accuracy, while also generating faithful explanations of its decisions?

Improving Answer Selection and Answer Triggering using Hard Negatives

no code implementations IJCNLP 2019 Sawan Kumar, Shweta Garg, Kartik Mehta, Nikhil Rasiwasia

In this paper, we establish the effectiveness of using hard negatives, coupled with a siamese network and a suitable loss function, for the tasks of answer selection and answer triggering.

Zero-shot Word Sense Disambiguation using Sense Definition Embeddings

1 code implementation ACL 2019 Sawan Kumar, Sharmistha Jat, Karan Saxena, Partha Talukdar

To overcome this challenge, we propose Extended WSD Incorporating Sense Embeddings (EWISE), a supervised model to perform WSD by predicting over a continuous sense embedding space as opposed to a discrete label space.
