Distilbert Similarity B32 3

🚀 shafin/distilbert-similarity-b32-3

This is a model that maps sentences & paragraphs to a 3-dimensional dense vector space, useful for tasks like clustering or semantic search.

🚀 Quick Start

This is a sentence-transformers model. It maps sentences and paragraphs to a 3-dimensional dense vector space and can be used for tasks such as clustering or semantic search.

📦 Installation

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

💻 Usage Examples

Basic Usage

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('shafin/distilbert-similarity-b32-3')
embeddings = model.encode(sentences)
print(embeddings)

🔧 Technical Details

The model is based on the sentence-transformers framework. It uses a DistilBertModel for feature extraction and then maps the features to a 3-dimensional vector space through multiple dense layers. The training process uses an OnlineContrastiveLoss and specific optimizer and scheduler settings to optimize the model.
