AShi846 / all-MiniLM-L6-v2_rag_ft_e-7

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/all-MiniLM-L6-v2_rag_ft_e-7")
# Run inference
sentences = [
    'Show a code snippet which represents the kernel of a Spectre\n  attack (use any convenient programming language or assembly).\n',
    "No, this will force other members to sit through an explanation that's not relevant to them, the colleague was right.",
    'Whatever your personal convictions, you have to adapt to the convention used by the project.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

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

  Now let $\xv$ be a random vector distributed according to the uniform distribution over the finite centered dataset $\xv_1, . . . , \xv_N$ from above. % Consider the problem of finding a unit vector, $\wv \in \R^D$, such that the random variable $\wv^ op \xx$ has \emph{maximal} variance. What does it mean for the data vectors $\xv_1, . . . , \xv_N$ to be centered, as for principle component analysis (PCA) to be meaningful? Use the notation $\x_{nd}$ for individual entries.	False.	0.1
  In the following problem Alice holds a string $x = \langle x_1, x_2, \ldots, x_n \rangle$ and Bob holds a string $y = \langle y_1, y_2, \ldots, y_n\rangle$. Both strings are of length $n$ and $x_i, y_i \in {1,2,\ldots, n}$ for $i=1,2, \ldots, n$. The goal is for Alice and Bob to use little communication to estimate the quantity \begin{align*} Q = \sum_{i=1}^n (x_i + y_i)^2,. \end{align*} A trivial solution is for Alice to transfer all of her string $x$ to Bob who then computes $Q$ exactly. However this requires Alice to send $\Theta(n \log n)$ bits of information to Bob. In the following, we use randomization and approximation to achieve a huge improvement on the number of bits transferred from Alice to Bob. Indeed, for a small parameter $\epsilon > 0$, your task is to devise and analyze a protocol of the following type: \begin{itemize} \item On input $x$, Alice uses a randomized algorithm to compute a message $m$ that consists of $O(\log (n)/\epsilon^2)$ bits. She then transmits ...	The algorithm is as follows: \begin{itemize} \item If $x_1 \geq W$, then do the exchange on day $1$ and receive $x_1$ Swiss francs. \item Otherwise, do the exchange on day $2$ and receive $x_2$ Swiss francs. \end{itemize} We now analyze its competitiveness. If $x_1 \geq W$, then our algorithm gets at least $W$ Swiss francs. Optimum is at most $W^2$ and so we are $1/W$ competitive. Otherwise if $x_1 < W$ then we get $x_2 \geq 1$ Swiss francs which is $x_2/ \max(x_2, x_1) \geq 1/W$ competitive.	0.1
  What does it mean that a processor implements precise exceptions?	When preparing benchmarks, your colleague should make sure that the inputs are representative of the real world, and complex enough to potentially detect performance bottlenecks. In this example, the inputs strings should be long enough.	0.1
