Pseudo-OOD training for robust language models

no code implementations17 Oct 2022 Dhanasekar Sundararaman, Nikhil Mehta, Lawrence Carin

The model is fine-tuned by introducing a new regularization loss that separates the embeddings of IND and OOD data, which leads to significant gains on the OOD prediction task during testing.

Debiasing Gender Bias in Information Retrieval Models

no code implementations2 Aug 2022 Dhanasekar Sundararaman, Vivek Subramanian

We definitively show that pre-trained models for IR do not perform well in zero-shot retrieval tasks when full fine-tuning of a large pre-trained BERT encoder is performed and that lightweight fine-tuning performed with adapter networks improves zero-shot retrieval performance almost by 20% over baseline.

Improving Downstream Task Performance by Treating Numbers as Entities

no code implementations7 May 2022 Dhanasekar Sundararaman, Vivek Subramanian, Guoyin Wang, Liyan Xu, Lawrence Carin

Numbers are essential components of text, like any other word tokens, from which natural language processing (NLP) models are built and deployed.

Learning Compressed Sentence Representations for On-Device Text Processing

1 code implementation ACL 2019 Dinghan Shen, Pengyu Cheng, Dhanasekar Sundararaman, Xinyuan Zhang, Qian Yang, Meng Tang, Asli Celikyilmaz, Lawrence Carin

Vector representations of sentences, trained on massive text corpora, are widely used as generic sentence embeddings across a variety of NLP problems.
