NECA: Network-Embedded Deep Representation Learning for Categorical Data

Xiaonan Gao, Sen Wu, Wenjun Zhou

We propose NECA, a deep representation learning method for categorical data. Built upon the foundations of network embedding and deep unsupervised representation learning, NECA dee…

Metadata Shaping: Natural Language Annotations for the Tail

Simran Arora, Sen Wu, Enci Liu +1

Language models (LMs) have made remarkable progress, but still struggle to generalize beyond the training data to rare linguistic patterns. Since rare entities and facts are preval…

Cross-Domain Data Integration for Named Entity Disambiguation in Biomedical Text

Maya Varma, Laurel Orr, Sen Wu +3

Named entity disambiguation (NED), which involves mapping textual mentions to structured entities, is particularly challenging in the medical domain due to the presence of rare ent…

Bootleg: Chasing the Tail with Self-Supervised Named Entity Disambiguation

Laurel Orr, Megan Leszczynski, Simran Arora +4

A challenge for named entity disambiguation (NED), the task of mapping textual mentions to entities in a knowledge base, is how to disambiguate entities that appear rarely in the t…

Precise High-Dimensional Asymptotics for Quantifying Heterogeneous Transfers

Fan Yang, Hongyang R. Zhang, Sen Wu +2

The problem of learning one task using samples from another task is central to transfer learning. In this paper, we focus on answering the following question: when does combining t…

Train and You'll Miss It: Interactive Model Iteration with Weak Supervision and Pre-Trained Embeddings

Mayee F. Chen, Daniel Y. Fu, Frederic Sala +5

Our goal is to enable machine learning systems to be trained interactively. This requires models that perform well and train quickly, without large amounts of hand-labeled data. We…

Understanding and Improving Information Transfer in Multi-Task Learning

Sen Wu, Hongyang R. Zhang, Christopher Ré

We investigate multi-task learning approaches that use a shared feature representation for all tasks. To better understand the transfer of task information, we study an architectur…

On the Generalization Effects of Linear Transformations in Data Augmentation

Sen Wu, Hongyang R. Zhang, Gregory Valiant +1

Data augmentation is a powerful technique to improve performance in applications such as image and text classification tasks. Yet, there is little rigorous understanding of why and…

Ivy: Instrumental Variable Synthesis for Causal Inference

Zhaobin Kuang, Frederic Sala, Nimit Sohoni +5

A popular way to estimate the causal effect of a variable x on y from observational data is to use an instrumental variable (IV): a third variable z that affects y only through x.…

Understanding the Downstream Instability of Word Embeddings

Megan Leszczynski, Avner May, Jian Zhang +3

Many industrial machine learning (ML) systems require frequent retraining to keep up-to-date with constantly changing data. This retraining exacerbates a large challenge facing ML…
