Do Encoder Representations of Generative Dialogue Models have sufficient summary of the Information about the task ?

1 code implementation SIGDIAL (ACL) 2021 Prasanna Parthasarathi, Joelle Pineau, Sarath Chandar

Predicting the next utterance in dialogue is contingent on encoding of users’ input text to generate appropriate and relevant response in data-driven approaches.

Sometimes We Want Ungrammatical Translations

1 code implementation Findings (EMNLP) 2021 Prasanna Parthasarathi, Koustuv Sinha, Joelle Pineau, Adina Williams

Rapid progress in Neural Machine Translation (NMT) systems over the last few years has focused primarily on improving translation quality, and as a secondary focus, improving robustness to perturbations (e. g. spelling).

Language Model-In-The-Loop: Data Optimal Approach to Learn-To-Recommend Actions in Text Games

no code implementations13 Nov 2023 Arjun Vaithilingam Sudhakar, Prasanna Parthasarathi, Janarthanan Rajendran, Sarath Chandar

In this work, we explore and evaluate updating LLM used for candidate recommendation during the learning of the text based game as well to mitigate the reliance on the human annotated gameplays, which are costly to acquire.

Deep Learning on a Healthy Data Diet: Finding Important Examples for Fairness

1 code implementation20 Nov 2022 Abdelrahman Zayed, Prasanna Parthasarathi, Goncalo Mordido, Hamid Palangi, Samira Shabanian, Sarath Chandar

The fairness achieved by our method surpasses that of data augmentation on three text classification datasets, using no more than half of the examples in the augmented dataset.

Local Structure Matters Most in Most Languages

no code implementations9 Nov 2022 Louis Clouâtre, Prasanna Parthasarathi, Amal Zouaq, Sarath Chandar

In this work, we replicate a study on the importance of local structure, and the relative unimportance of global structure, in a multilingual setting.

Local Structure Matters Most: Perturbation Study in NLU

no code implementations Findings (ACL) 2022 Louis Clouatre, Prasanna Parthasarathi, Amal Zouaq, Sarath Chandar

Recent research analyzing the sensitivity of natural language understanding models to word-order perturbations has shown that neural models are surprisingly insensitive to the order of words.

A Brief Study on the Effects of Training Generative Dialogue Models with a Semantic loss

1 code implementation SIGDIAL (ACL) 2021 Prasanna Parthasarathi, Mohamed Abdelsalam, Joelle Pineau, Sarath Chandar

Neural models trained for next utterance generation in dialogue task learn to mimic the n-gram sequences in the training set with training objectives like negative log-likelihood (NLL) or cross-entropy.

Memory Augmented Optimizers for Deep Learning

2 code implementations ICLR 2022 Paul-Aymeric McRae, Prasanna Parthasarathi, Mahmoud Assran, Sarath Chandar

Popular approaches for minimizing loss in data-driven learning often involve an abstraction or an explicit retention of the history of gradients for efficient parameter updates.

no code implementations15 Apr 2021 Prasanna Parthasarathi, Koustuv Sinha, Joelle Pineau, Adina Williams

Rapid progress in Neural Machine Translation (NMT) systems over the last few years has been driven primarily towards improving translation quality, and as a secondary focus, improved robustness to input perturbations (e. g. spelling and grammatical mistakes).

UnNatural Language Inference

1 code implementation ACL 2021 Koustuv Sinha, Prasanna Parthasarathi, Joelle Pineau, Adina Williams

We provide novel evidence that complicates this claim: we find that state-of-the-art Natural Language Inference (NLI) models assign the same labels to permuted examples as they do to the original, i. e. they are largely invariant to random word-order permutations.

On Task-Level Dialogue Composition of Generative Transformer Model

1 code implementation EMNLP (insights) 2020 Prasanna Parthasarathi, Arvind Neelakantan, Sharan Narang

In this work, we begin by studying the effect of training human-human task-oriented dialogues towards improving the ability to compose multiple tasks on Transformer generative models.
