SentenceTransformer based on sentence-transformers/all-mpnet-base-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-mpnet-base-v2 on the umsb-episodic-memory dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for retrieval.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'e medication administration date. This parameter corresponds to the dosageInstruction.timing.repeat.boundsPeriod element\nMedication orders that do not have start and end dates within the search parameter dates are filtered. If the environment supports multiple time zones, the search dates are adjusted one day in both directions, so more medications might be returned than expected. Use caution when filtering a medication list by date as it is possible to filter out important active medications. Starting in the November 2022 version of Epic, this parameter is respected',
