Anomaly-Injected Deep Support Vector Data Description for Text Outlier Detection
Zeyu You, Yichu Zhou, Tao Yang +1
Anomaly detection or outlier detection is a common task in various domains, which has attracted significant research efforts in recent years. Existing works mainly focus on structu…
Putting Words in BERT's Mouth: Navigating Contextualized Vector Spaces with Pseudowords
Taelin Karidi, Yichu Zhou, Nathan Schneider +2
We present a method for exploring regions around individual points in a contextualized vector space (particularly, BERT space), as a way to investigate how these regions correspond…
A Closer Look at How Fine-tuning Changes BERT
Yichu Zhou, Vivek Srikumar
Given the prevalence of pre-trained contextualized representations in today's NLP, there have been many efforts to understand what information they contain, and why they seem to be…
DirectProbe: Studying Representations without Classifiers
Yichu Zhou, Vivek Srikumar
Understanding how linguistic structures are encoded in contextualized embedding could help explain their impressive performance across NLP@. Existing approaches for probing them us…
