Representation Deficiency in Masked Language Modeling

1 code implementation4 Feb 2023 Yu Meng, Jitin Krishnan, Sinong Wang, Qifan Wang, Yuning Mao, Han Fang, Marjan Ghazvininejad, Jiawei Han, Luke Zettlemoyer

In this work, we offer a new perspective on the consequence of such a discrepancy: We demonstrate empirically and theoretically that MLM pretraining allocates some model dimensions exclusively for representing $\texttt{[MASK]}$ tokens, resulting in a representation deficiency for real tokens and limiting the pretrained model's expressiveness when it is adapted to downstream data without $\texttt{[MASK]}$ tokens.

Cross-Lingual Text Classification of Transliterated Hindi and Malayalam

1 code implementation31 Aug 2021 Jitin Krishnan, Antonios Anastasopoulos, Hemant Purohit, Huzefa Rangwala

Transliteration is very common on social media, but transliterated text is not adequately handled by modern neural models for various NLP tasks.

Common-Knowledge Concept Recognition for SEVA

1 code implementation26 Mar 2020 Jitin Krishnan, Patrick Coronado, Hemant Purohit, Huzefa Rangwala

We build a common-knowledge concept recognition system for a Systems Engineer's Virtual Assistant (SEVA) which can be used for downstream tasks such as relation extraction, knowledge graph construction, and question-answering.

Unsupervised and Interpretable Domain Adaptation to Rapidly Filter Tweets for Emergency Services

1 code implementation4 Mar 2020 Jitin Krishnan, Hemant Purohit, Huzefa Rangwala

As deep networks struggle with sparse datasets, we show that this can be improved by sharing a base layer for multi-task learning and domain adversarial training.

Diversity-Based Generalization for Unsupervised Text Classification under Domain Shift

1 code implementation25 Feb 2020 Jitin Krishnan, Hemant Purohit, Huzefa Rangwala

At present, the state-of-the-art unsupervised domain adaptation approaches for subjective text classification problems leverage unlabeled target data along with labeled source data.
