-## Usage
+## 🚀 Model Description
 
-### Direct Usage (Sentence Transformers)
+**DIMI-embedding-v3-silma-sts-matryoshka** is a cutting-edge multilingual sentence embedding model specifically fine-tuned for Arabic-English semantic textual similarity tasks. Built upon the robust DIMI-embedding-v2 architecture, this model leverages **Matryoshka Representation Learning** combined with **CoSENT Loss** to deliver exceptional performance across multiple embedding dimensions.
 
-First install the Sentence Transformers library:
+### ✨ Key Features
 
-```bash
-pip install -U sentence-transformers
-```
+- **Multi-dimensional embeddings**: Supports output dimensions of 768, 512, 256, 128, and 64
+- **Bilingual expertise**: Optimized for Arabic and English text processing
+- **Matryoshka architecture**: Efficient embedding computation at multiple granularities
+- **State-of-the-art performance**: Fine-tuned on the comprehensive Silma Arabic-English STS dataset
+- **Cosine similarity optimized**: Perfect for semantic similarity and retrieval tasks
+
+## 📊 Model Performance
+
+The model demonstrates exceptional performance across different embedding dimensions:
+
+### Training Techniques
+
+This model was trained using advanced techniques for optimal performance:
+
+- **Matryoshka Representation Learning**: Enables efficient embeddings at multiple dimensions [768, 512, 256, 128, 64] without retraining

+    "This is a beautiful example of artificial intelligence",  # English
+    "التعلم الآلي يغير العالم",  # Arabic
+    "Machine learning is changing the world"  # English
 ]
+
+# Generate embeddings
 embeddings = model.encode(sentences)
-print(embeddings.shape)
-# [3, 768]
+print(f"Embedding shape: {embeddings.shape}")
 
-# Get the similarity scores for the embeddings
-similarities = model.similarity(embeddings, embeddings)
-print(similarities.shape)
-# [3, 3]
+# Calculate cosine similarity
+from sklearn.metrics.pairwise import cosine_similarity
+similarity_matrix = cosine_similarity(embeddings)
+print("Similarity matrix:")
+print(similarity_matrix)

+### Matryoshka Embeddings Usage
+
+```python
+# Use different embedding dimensions
+dimensions = [768, 512, 256, 128, 64]
+
+for dim in dimensions:
+    # Truncate embeddings to specific dimension
+    truncated_embeddings = embeddings[:, :dim]
+    print(f"Dimension {dim}: {truncated_embeddings.shape}")
+    
+    # Calculate similarity with truncated embeddings
+    similarity = cosine_similarity(truncated_embeddings)
+    print(f"Average similarity at {dim}d: {similarity.mean():.4f}")

+### Semantic Search Example
+
+```python
+import numpy as np
+
+# Query and corpus
+query = "ما هو الذكاء الاصطناعي؟"  # "What is artificial intelligence?"
+corpus = [
+    "الذكاء الاصطناعي هو محاكاة الذكاء البشري",
+    "Machine learning is a subset of AI",
+    "Deep learning uses neural networks",
+    "التعلم العميق يستخدم الشبكات العصبية"
+]
+
+# Encode query and corpus
+query_embedding = model.encode([query])
+corpus_embeddings = model.encode(corpus)
+
+# Find most similar documents
+similarities = cosine_similarity(query_embedding, corpus_embeddings)[0]
+top_indices = np.argsort(similarities)[::-1]
+
+print(f"Query: {query}")
+print("\nMost similar documents:")
+for i, idx in enumerate(top_indices[:3]):
+    print(f"{i+1}. {corpus[idx]} (similarity: {similarities[idx]:.4f})")

+- **Supported Dimensions**: [768, 512, 256, 128, 64]
+- **Max Sequence Length**: 512 tokens
+- **Pooling Method**: Mean pooling
+- **Similarity Function**: Cosine similarity
+
+## 📊 Training Details
+
+### Dataset
+- **Primary Dataset**: silma-ai/silma-arabic-english-sts-dataset-v1.0
+- **Evaluation Dataset**: MTEB STS17 (ar-ar)
+- **Training Samples**: ~24,000+ multilingual sentence pairs
+- **Evaluation Samples**: 100 held-out pairs
+
+### Training Configuration
+- **Batch Size**: 16
+- **Epochs**: 4
+- **Learning Rate**: Warmup ratio 0.1
+- **Precision**: FP16
+- **Evaluation Strategy**: Every 100 steps
+- **Best Model Selection**: Highest Spearman correlation on 768d embeddings
+
+### Hardware Requirements
+- **GPU**: CUDA-compatible GPU recommended
+- **Memory**: 16GB+ RAM for training
+- **Storage**: 2GB+ for model weights
+
+## 🎯 Applications
+
+This model excels in various NLP tasks:
+
+- **Semantic Textual Similarity**: Measure similarity between Arabic-English text pairs
+- **Information Retrieval**: Find relevant documents in multilingual corpora
+- **Paraphrase Detection**: Identify semantically equivalent sentences
+- **Cross-lingual Search**: Search Arabic content with English queries and vice versa
+- **Clustering**: Group similar multilingual documents
+- **Recommendation Systems**: Content-based recommendations across languages
+
+## ⚖️ Limitations and Bias
+
+- Primarily optimized for Arabic and English; performance on other languages may vary
+- Performance may degrade on domain-specific technical terminology
+- Potential cultural and linguistic biases inherited from training data
+- Best performance achieved with sentence-level inputs rather than single words
