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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'What is the purpose of the Rapid Borate Stop Valve in Reactor Control?',
    'Locates and discusses opening 1CV175, Rapid Borate Stop Valve by disengaging clutch and rotating handwheel (counterclockwise).',
    'CLOSE the Air Supply Isolation Valve, 12CV160 A/S, AIR SUPPLY FOR 12CV160.',
]
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 is the concentration of H-3 in µCi/ml?`	`H-3 has a concentration of 8.5E-10 µCi/ml.`	`The isotope Rb-89 has a release rate of 4.7E-05 Ci/yr.`
`gamma calibration procedures`	`Gamma Calibration: GM detectors positioned perpendicular to source for M-44-9 in which the front of probe faces source.`	`Effective calibration of GM detectors is crucial for accurate measurement. Procedures often involve using a consistent radiation source and monitoring the response of various detector models across multiple energy levels.`
`What is the function of the TAP-A program in thermal analysis?`	`The TAP-A program is applicable to both “transient and steady-state heat transfer in multidimensional systems having arbitrary geometric configurations, boundary conditions, initial conditions, and physical properties.`	`The wall panel model for the crane wall is 48 ft long with 8 axial stations each 6 ft in length.`
