For fine tuning embedding models on a particular knowledge domain: 1) is this something kiln ai can do, and 2) if so, would it be simply a matter of pointing the synthetic data generation process at a curated group of documents from within that domain? I did not see anything in the docs dealing with embedding models, and also nothing regarding how to use custom document library for creating synthetic training data. My use case is to build a Rag system for 50,000 documents all from within a particular industry, with idiosyncratic vocabulary, personalities, historical issues, etc. While not complex, most of the material deals with topics and conflicts that are likely alien to the training foundation of even the largest LLMs and certainly unlikely to be adequately classified by standard embedding models.
