NYUTron (pronounced: new-tron)

The Health Sciences Library is excited to support innovative AI projects at NYU Langone Health. One such initiative is NYUTron. Led by Dr. Eric Oermann, Assistant Professor of Neurosurgery, Radiology, and Data Science, and Dr. Yin Aphinyanaphongs,Director of Operational Data Science and Machine Learning, NYUTron is a large language model (LLM) platform trained on a decade's worth of clinical notes from NYU Langone Health's inpatient records. Its purpose is to handle unstructured text and perform tasks involving categorization and numerical prediction.

The work behind NYUTron was published in Nature and scored exceptionally high (in the 99th percentile) based on alternative metrics Metrics that are not based solely on traditional academic citations but include various indicators like social media mentions, downloads, and online discussions.. This substantiates its impact and popularity within the scientific community.

Enhancing NLP in Healthcare:

A de-identified model, stripped of protected health information (PHI), is free for use by all NYU Langone Health (NYULH) faculty and staff. To access the de-identified model, please submit a request to the Predictive Analytics Unit (PAU).

We encourage members of the NYU Langone Health community to explore and utilize this model for their own predictive tasks. See the >Jiang LY, et.al. research paper on health system-scale language models for examples of potential use cases and further details.

Future Plans:

The NYUTron team plans to expand its range of models, including BERT-like models Bidirectional Encoder Representations from Transformers (BERT), developed by Google, is a language model designed to learn from text without labels. It pays attention to both the words before and after each word in a sentence. This dual focus helps BERT understand language nuances. The model can then be fine-tuned for specific tasks like question answering and facilitating meaningful conversation, making it versatile without requiring significant modifications. as well as generative models. The team's goal is to provide Natural Language Processing (NLP) tools within the electronic health record (EHR) universal interface.
