About Me
I am currently a PhD candidate in Computational Linguistics with the University of Washington Department of Linguistics, where I am advised by Drs. Gina-Anne Levow and Shane Steinert-Threlkeld. I also belong to Dr. Steinert-Threlkeld's CLMBR lab. Before coming to UW, I earned a B.S. in Linguistics and Russian at Tulane University.
My research develops methods to improve the efficacy of Natural Language Processing (NLP) tools for under-resourced languages (those lacking the abundant data needed to train modern machine learning models). The most common approach to building machine learning systems is to train huge neural networks on high-resource languages like English and Chinese, for which vast amounts of textual data (i.e. hundreds of gigabytes) are available. Such techniques are inapplicable to the majority of the world's languages, which lack the large requisite text datasets. This methodological gap undermines the potentially vital role these systems can play in creating tools such as assisted completion and keyboard auto-correct features, automatic speech recognition, and machine translation services. Development of such tools helps ensure that minority and endangered languages can thrive in the digital era. To address this gap, I specialize in machine learning techniques that are applicable to under-resourced languages, with a strong emphasis on:
- unsupervised/self-supervised learning, enabling training with raw text or much smaller amounts of specialized data than supervised paradigms
- multilingual modeling, allowing language data to be pooled by training on more than one language at once
- transfer learning, leveraging existing models trained in higher-resource languages for use with new, low-resource ones
My contributions to this agenda include projects that focus on unsupervised morpheme segmentation, linguistically-informed multilingual modeling, cross-lingual model transfer, and unsupervised machine translation.
