+# HSDN - Hierarchical Semantic Decomposition Network
+
+A hierarchical retriever that decomposes embeddings into multi-resolution subspaces:
+- **Level 1 (64D)**: Domain-level semantics
+- **Level 2 (128D)**: Subdomain-level semantics  
+- **Level 3 (576D)**: Instance-level semantics
+
+## Usage
+
+```python
+import torch
+from sentence_transformers import SentenceTransformer
+
+# Load base encoder
+encoder = SentenceTransformer('BAAI/bge-base-en-v1.5')
+
+# Load HSDN weights
+from huggingface_hub import hf_hub_download
+weights_path = hf_hub_download(repo_id="Ishaank18/hsdn-retriever", filename="best_model.pt")
+state_dict = torch.load(weights_path, map_location='cpu')
+
+# See cmrl_complete.py for full HSDNRetriever class
+```
+
+## Architecture
+
+- Base encoder: BAAI/bge-base-en-v1.5
+- Level 1 (Domain): 64D
+- Level 2 (Subdomain): 128D
+- Level 3 (Instance): 576D
+- Total: 768D
+
+## Training
+
+Trained with hierarchical contrastive loss + orthogonality constraints.
+
+## Part of CMRL Project
+
+This retriever is part of the Contextual Multi-Resolution Learning (CMRL) system
+for adaptive STEM tutoring.
