Using text embedding models and vector databases as text classifiers with the example of medical data
<|reference_start|>Using text embedding models and vector databases as text classifiers with the example of medical data: The advent of Large Language Models (LLMs) is promising and has found application in numerous fields, but as it often is with the medical field, the bar is typically quite high [5]. In tandem with LLMs, vector embedding models and vector databases provide a robust way of expressing numerous modes of data that are easily digestible by typical machine learning models. Along with the ease of adding information, knowledge, and data to these vector databases, they provide a compelling reason to apply them in numerous fields where the task of retrieving information is typically done by humans. Researchers at Google have developed a clear alternative model, Med-PaLM [6] specifically designed to match a clinician's level of accuracy when it comes to medical knowledge. When training classifiers, and developing models, it is imperative to maintain factuality and reduce bias [4]. Here, we explore the use of vector databases and embedding models as a means of encoding, and classifying text with the example and application in the field of medicine. We show the robustness of these tools depends heavily on the sparsity of the data presented, and even with low amounts of data in the vector database itself, the vector database does a good job at classifying data [9]. Using various LLMs to generate the medical data, we also understand the limitations of the medical knowledge of these models and encourage further expert medical review of our testing data. By using vector databases to classify a clinician's notes on a patient presented with a certain ailment, we understand the limitations of such methods, but also the promise of their prospective use and with continued testing and experimentation, hope to explore a unique use case of vector databases and embedding models.<|reference_end|>
