Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

bash

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'If the difference between the length and breadth of a rectangle is 23 m and its perimeter is 206 m, what is its area? A. 2510. B. 2530. C. 2515. D. 2520.',
    "A circle with radius $3$ has a sector with a $345^\\circ$ central angle. What is the area of the sector? ${9\\pi}$ $\\color{#9D38BD}{345^\\circ}$ ${\\dfrac{69}{8}\\pi}$ ${3}$\n\nHints:\nFirst, calculate the area of the whole circle. Then the area of the sector is some fraction of the whole circle's area. $A_c = \\pi r^2$ $A_c = \\pi (3)^2$ $A_c = 9\\pi$ The ratio between the sector's central angle $\\theta$ and $360^\\circ$ is equal to the ratio between the sector's area, $A_s$ , and the whole circle's area, $A_c$ $\\dfrac{\\theta}{360^\\circ} = \\dfrac{A_s}{A_c}$ $\\dfrac{345^\\circ}{360^\\circ} = \\dfrac{A_s}{9\\pi}$ $\\dfrac{23}{24} = \\dfrac{A_s}{9\\pi}$ $\\dfrac{23}{24} \\times 9\\pi = A_s$ $\\dfrac{69}{8}\\pi = A_s$",
    'The area of a rectangular surface is calculated as its length multiplied by its width.',
]
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]

You, too, can participate in this time-honored tradition after looking into dog sledding adventures and tours. Alaska Dog Sledding It offers two dog sledding tours in Alaska, the Golsovia Dog Trip and the Iditarod Dog Trip. On both trips, you will learn how to drive your own dog team. The Golsovia Dog Trip lasts six days. The Iditarod Dog Trip is held just before the internationally famous Iditarod race so that participants will be able to attend the Iditarod events. For more information, please see: Alaska Dog Sledding Greenland Expedition Specialists Travel through the shining ice and snow on the land of East Greenland via dog sledding. During this dog sledding vacation, you will be camping during the cold of winter and will take part in caring for the dogs and the camps. They also organize and guide kiting trips, sea kayaking trips and mountaineering vacations.

In many dog camps dogs can play and socialize throughout the day while supervised by their owners. Some of the activities at a dog camp might include running, fetching balls or frisbees, chasing other dogs, tug of war, socializing amongst playmates, and lessons.</code> | <code>Dog camp Dog camp: Dog camp is a form of vacation for owners accompanied by their dogs with dog-centric activities ranging from casual recreational playtime to serious obedience or sport training.

How old is Ishaan? Hints: We can use the given information to write down two equations that describe the ages of Ishaan and Christopher. Let Ishaan's current age be $i$ and Christopher's current age be $c$. ${i = 3c}$ ${i = c + 14}$ Now we have two independent equations, and we can solve for our two unknowns. One way to solve for $i$ is to solve the second equation for $c$ and substitute that value into the first equation. Solving our second equation for $c$, we get: ${c = i - 14}$. Substituting this into our first equation, we get the equation: ${i = 3}{(i - 14)}$ which combines the information about $i$ from both of our original equations. Simplifying the right side of this equation, we get: $i = 3i - 42$. Solving for $i$, we get: $2 i = 42$. $i = 21$.</code> | | <code>Blood specimen for neonatal thyroid screening is obtained at: A. Cord blood. B. 24 hours after bih. C. 48 hours after bih.

Typically, this stimulation test involves determining basal TSH levels and levels 15 to 30 minutes after an intravenous bolus of TRH. Normally, TSH would rise into the concentration range measurable with less sensitive TSH assays.</code> | <code>Blood gas test Blood gas test: A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and the level and base excess of bicarbonate. The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries. The blood gas tension levels of partial pressures can be used as indicators of ventilation, respiration and oxygenation. Analysis of paired arterial and venous specimens can give insights into the aetiology of acidosis in the newborn.</code> |
