AShi846 / fine-tuned-embedding-model

SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2 . It maps sentences & paragraphs to a 384-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("AShi846/fine-tuned-embedding-model")
# Run inference
sentences = [
    ' The [t-statistic](https://en.wikipedia.org/wiki/T-statistic) is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. In a t-test, the higher the t-statistic, the more confidently we can reject the null hypothesis. Use `numpy.random` to create four samples, each of size 30:\n- $X \\sim Uniform(0,1)$\n- $Y \\sim Uniform(0,1)$\n- $Z = X/2 + Y/2 + 0.1$\n- $K = Y + 0.1$',

    'Including a major bugfix in a minor release instead of a bugfix release will cause an incoherent changelog and an inconvenience for users who wish to only apply the patch without any other changes. The bugfix could be as well an urgent security fix and should not wait to the next minor release date.',

embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

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

  Describe the techniques that typical dynamically scheduled processors use to achieve the same purpose of the following features of Intel Itanium: (a) Predicated execution; (b) advanced loads---that is, loads moved before a store and explicit check for RAW hazards; (c) speculative loads---that is, loads moved before a branch and explicit check for exceptions; (d) rotating register file.	Alice and Bob can both apply the AMS sketch with constant precision and failure probability $1/n^2$ to their vectors. Then Charlie subtracts the sketches from each other, obtaining a sketch of the difference. Once the sketch of the difference is available, one can find the special word similarly to the previous problem.	0.1
