      If you receive a BharatPe speaker that you didn't order, please contact
      BharatPe support immediately. They will assist in resolving the issue and
      advise on the next steps.
    sentences:
      - Can I control multiple BharatPe speakers from one app?
      - >-
        What to do if the BharatPe speaker's transaction announcements are
        intermittently silent?
      - What should I do if I receive a BharatPe speaker without ordering it?
  - source_sentence: >-
      Remote control capabilities depend on the model of the BharatPe speaker.
      Check if your model supports remote control through the BharatPe app or a
      connected device.
    sentences:
      - How do I update my personal details in my Bharatpe account?
      - What are the benefits of the BharatPe speaker?
      - Can I control the BharatPe speaker remotely?
  - source_sentence: >-
      If the announcements are not clear, check the speaker's volume settings
      and ensure it's not placed near noisy equipment. If clarity doesn't
      improve, the speaker may need servicing.
    sentences:
      - >-
        What to do if my BharatPe speaker is not syncing with the transaction
        history in the app?
      - What should I do if the speaker is not announcing payments clearly?
      - The speaker doesn't produce any sound, what can be done?
  - source_sentence: >-
      If the speaker is causing interference, try relocating it or other devices
      to reduce the interference. Ensure there's a reasonable distance between
      the speaker and other wireless equipment.
    sentences:
      - Can I use my Bharatpe device for international transactions?
      - How do I know if my BharatPe speaker is under warranty?
      - >-
        What should I do if the BharatPe speaker is causing interference with
        other wireless devices?
  - source_sentence: >-
      I can understand and respond in multiple Indian regional languages. Feel
      free to communicate with me in the language you're most comfortable with.
    sentences:
      - How can I check if the BharatPe speaker is receiving a network signal?
      - Bharti, can you provide tips for effective online communication?
      - Bharti, what languages can you understand and respond to?

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("MANMEET75/pubmedbert-base-embedding-Chatbot-Matryoshk")
# Run inference
sentences = [
    "I can understand and respond in multiple Indian regional languages. Feel free to communicate with me in the language you're most comfortable with.",
    'Bharti, what languages can you understand and respond to?',
    'Bharti, can you provide tips for effective online communication?',
]
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]
