Data augmentation is an important component in the robustness evaluation of models in natural language processing (NLP) and in enhancing the diversity of the data they are trained on.

Few-shot Controllable Style Transfer for Low-Resource Multilingual Settings

no code implementations ACL 2022 Kalpesh Krishna, Deepak Nathani, Xavier Garcia, Bidisha Samanta, Partha Talukdar

When compared to prior work, our model achieves 2-3x better performance in formality transfer and code-mixing addition across seven languages.

Do Long-Range Language Models Actually Use Long-Range Context?

no code implementations EMNLP 2021 Simeng Sun, Kalpesh Krishna, Andrew Mattarella-Micke, Mohit Iyyer

Language models are generally trained on short, truncated input sequences, which limits their ability to use discourse-level information present in long-range context to improve their predictions.

Hurdles to Progress in Long-form Question Answering

1 code implementation NAACL 2021 Kalpesh Krishna, Aurko Roy, Mohit Iyyer

The task of long-form question answering (LFQA) involves retrieving documents relevant to a given question and using them to generate a paragraph-length answer.

An Analysis of Frame-skipping in Reinforcement Learning

no code implementations7 Feb 2021 Shivaram Kalyanakrishnan, Siddharth Aravindan, Vishwajeet Bagdawat, Varun Bhatt, Harshith Goka, Archit Gupta, Kalpesh Krishna, Vihari Piratla

In this paper, we investigate the role of the parameter $d$ in RL; $d$ is called the "frame-skip" parameter, since states in the Atari domain are images.

Reformulating Unsupervised Style Transfer as Paraphrase Generation

1 code implementation EMNLP 2020 Kalpesh Krishna, John Wieting, Mohit Iyyer

Modern NLP defines the task of style transfer as modifying the style of a given sentence without appreciably changing its semantics, which implies that the outputs of style transfer systems should be paraphrases of their inputs.

Thieves on Sesame Street! Model Extraction of BERT-based APIs

1 code implementation ICLR 2020 Kalpesh Krishna, Gaurav Singh Tomar, Ankur P. Parikh, Nicolas Papernot, Mohit Iyyer

We study the problem of model extraction in natural language processing, in which an adversary with only query access to a victim model attempts to reconstruct a local copy of that model.

Generating Question-Answer Hierarchies

2 code implementations ACL 2019 Kalpesh Krishna, Mohit Iyyer

The process of knowledge acquisition can be viewed as a question-answer game between a student and a teacher in which the student typically starts by asking broad, open-ended questions before drilling down into specifics (Hintikka, 1981; Hakkarainen and Sintonen, 2002).

Syntactically Supervised Transformers for Faster Neural Machine Translation

1 code implementation ACL 2019 Nader Akoury, Kalpesh Krishna, Mohit Iyyer

Standard decoders for neural machine translation autoregressively generate a single target token per time step, which slows inference especially for long outputs.

Trick or TReAT: Thematic Reinforcement for Artistic Typography

1 code implementation19 Mar 2019 Purva Tendulkar, Kalpesh Krishna, Ramprasaath R. Selvaraju, Devi Parikh

An approach to make text visually appealing and memorable is semantic reinforcement - the use of visual cues alluding to the context or theme in which the word is being used to reinforce the message (e. g., Google Doodles).

Revisiting the Importance of Encoding Logic Rules in Sentiment Classification

1 code implementation EMNLP 2018 Kalpesh Krishna, Preethi Jyothi, Mohit Iyyer

We analyze the performance of different sentiment classification models on syntactically complex inputs like A-but-B sentences.

Hierarchical Multitask Learning for CTC-based Speech Recognition

no code implementations17 Jul 2018 Kalpesh Krishna, Shubham Toshniwal, Karen Livescu

Previous work has shown that neural encoder-decoder speech recognition can be improved with hierarchical multitask learning, where auxiliary tasks are added at intermediate layers of a deep encoder.

A Study of All-Convolutional Encoders for Connectionist Temporal Classification

no code implementations28 Oct 2017 Kalpesh Krishna, Liang Lu, Kevin Gimpel, Karen Livescu

We explore whether deep convolutional neural networks (CNNs) can be used effectively instead of RNNs as the "encoder" in CTC.
