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("sachin19566/bge-base-en-v1.5-course-recommender-v1")
# Run inference
sentences = [
    'ARIMA',
    'Learn how to apply seasonal analysis and ARIMA models and how to decompose and identify seasonal and non-seasonal factors all while learning the nuances of building sophisticated time series models.',
    'Prerequisites required: Intro to Time Series Analysis',
]
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]
