SentenceTransformer based on Snowflake/snowflake-arctic-embed-m

This is a sentence-transformers model finetuned from Snowflake/snowflake-arctic-embed-m. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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("bsmith3715/legal-ft-cert-challenge_final")
# Run inference
sentences = [
    'How did users interact with the clipal1 R package to update their code?',
    'clipal1, a (now-superseded) R package that allows users to select erroring code, press a keyboard shortcut, wait a moment, and watch the updated code be inlined in to the selection.',
    'As for the disadvantages, there are all sorts of UI bummers about this approach. Above all, these packages write directly to your files. This is great in that it removes the need to copy and paste, and when the model’s response is spot on, it’s awesome. At the same time, if the model starts rambling in an .R file or you want to confirm some difference between your previous code and the new code, the fact that these packages just write right into your files can be a bit annoying. Many other inline LLM code-assist tools out there are based on diffs—they show you proposed changes and some UI element that allows you to accept them, reject them, or ask for revisions. This requires one more step between asking for an LLM to do something and the',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

  What are the names of the three experimental R packages that Simon Couch has been exploring?	Simon Couch The last few months, I’ve been exploring how AI/LLMs might make my time developing R packages and doing data science more productive. This post will describe three experimental R packages— pal, ensure, and gander—that came out of that exploration, and the core tools underlying them. Taken together, I’ve found that these packages allow me to automate many of the less interesting parts of my work, turning all sorts of 45-second tasks into 5-second ones. Excitement from folks in the community has been very encouraging so far, and I’m looking forward to getting each of these packages buttoned up and sent off to CRAN in the coming weeks! Background
