Complexity-Weighted Loss and Diverse Reranking for Sentence Simplification
2019 · arXiv (Cornell University)
Sentence simplification is the task of rewriting texts so they are easier to understand. Recent research has applied sequence-to-sequence (Seq2Seq) models to this task, focusing largely on training-time improvements via reinforcement learning and memory augmentation. …

Using the Poly-encoder for a COVID-19 Question Answering System
2020
To combat misinformation regarding COVID-19 during this unprecedented pandemic, we propose a conversational agent that answers questions related to COVID-19. We adapt the Poly-encoder (Humeau et al., 2020) model for informational retrieval from FAQs. We …

Conceptor-Aided Debiasing of Large Language Models
2023
Pre-trained large language models (LLMs) reflect the inherent social biases of their training corpus. Many methods have been proposed to mitigate this issue, but they often fail to debias or they sacrifice model accuracy. We …

Unsupervised Post-Processing of Word Vectors via Conceptor Negation
2019 · Proceedings of the AAAI Conference on Artificial Intelligence
Word vectors are at the core of many natural language processing tasks. Recently, there has been interest in post-processing word vectors to enrich their semantic information. In this paper, we introduce a novel word vector …
