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

This is a sentence-transformers model finetuned from sentence-transformers/paraphrase-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("jtatman/paraphrase-minilm-l6-psychology")
# Run inference
sentences = [
    'What term would a behaviorist use for an external event or object that elicits a behavior in an organism?',
    '(',
    '(A)Punishment  (B)Reward  (C)Instinct  (D)Responsen  (E)Reinforcement',
]
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]

  Which of the following disorders is associated with increased risk of mood disorders and suicide?	A	A. Multiple sclerosis B. Huntingtons disease C. Epilepsyn D. Brain injury E. All of the above
  A 68-year-old man is admitted to an acute psychiatric unit for severe suicidal ideation. He is very much preoccupied with death and refuses to agree to a contract for safety. The diagnostician determines the patient to be severely depressed because of noncompliance with medication and severe social stressors. The patient refuses to take any medication because, he says, Nothing will change, anyway. He also stops eating and drinking and becomes increasingly dehydrated. A reasonable choice of treatment in this patient would be to	A	A. Persuade the patient to take antidepressants B. Wait and watch for the patient to change his mind C. Restrain the patient and administer intravenous fluids D. Prescribe electroconvulsive therapy E. Prescribe intensive psychotherapy 41. A 48-year-old man with treatment-resistant schizophrenia has been relatively stable for the past 6 months on clozapine. On a routine follow-up visitn the patient is observed to be depressed and reports lack of appetite and insomnian among other features of depression. The attending psychiatrist decides to treat the patient with antidepressants. Which of the following antidepressants would mandate particular caution in this patient?n A. Mirtazapine B. Fluoxetine C. Sertralinen D. Citalopram E. Trazodone
  Which of the following is the best definition of a response?	(	(A)A cognitive interpretation or a memory of an eventn (B)An external event or object that elicits a behavior in an organismn (C)A long-term change in behavior caused by past experiencesn (D)External energy or chemicals that are changed into neural impulsesn (E)A physical reaction or behavior elicited by an external event or object
