zacbrld / MNLP_M3_document_encoder_V1

SentenceTransformer based on zacbrld/MNLP_M2_document_encoder

This is a sentence-transformers model finetuned from zacbrld/MNLP_M2_document_encoder . 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("zacbrld/MNLP_M3_document_encoder_V1")
# Run inference
sentences = [

embeddings = model.encode(sentences)
print(embeddings.shape)

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

  chemistry experiment	Since 1982, research has been conducted to develop technologies, commonly referred to as electronic noses, that could detect and recognize odors and flavors Application areas include food, medicine and the environment
  quantum physics	Hydro electric - Hydro-electric turbomachinery uses potential energy stored in water to flow over an open impeller to turn a generator which creates electricity Steam turbines - Steam turbines used in power generation come in many different variations The overall principle is high pressure steam is forced over blades attached to a shaft, which turns a generator As the steam travels through the turbine, it passes through smaller blades causing the shaft to spin faster, creating more electricity Gas turbines - Gas turbines work much like steam turbines Air is forced in through a series of blades that turn a shaft Then fuel is mixed with the air and causes a combustion reaction, increasing the power This then causes the shaft to spin faster, creating more electricity Windmills - Also known as a wind turbine, windmills are increasing in popularity for their ability to efficiently use the wind to generate electricity Although they come in many shapes and sizes, the most common one is the la...
  physics law	Backlash in gear couplings allows for slight angular misalignment There can be significant backlash in unsynchronized transmissions because of the intentional gap between the dogs in dog clutches The gap is necessary to engage dogs when input shaft (engine) speed and output shaft (driveshaft) speed are imperfectly synchronized If there was a smaller clearance, it would be nearly impossible to engage the gears because the dogs would interfere with each other in most configurations In synchronized transmissions, synchromesh solves this problem However, backlash is undesirable in precision positioning applications such as machine tool tables It can be minimized by choosing ball screws or leadscrews with preloaded nuts, and mounting them in preloaded bearings A preloaded bearing uses a spring and/or a second bearing to provide a compressive axial force that maintains bearing surfaces in contact despite reversal of the load direction
