+# 🧠 GASM Enhanced - Geometric Language Processing
+
+A HuggingFace Space for geometric language processing using GASM (Geometric Attention with Spatial & Mathematical understanding).
+
+## ✨ Features
+
+- **SE(3) Invariant Processing**: Mathematically correct geometric attention mechanisms
+- **Real-time Entity Extraction**: Advanced text analysis with spatial relationship detection  
+- **Interactive Visualizations**: 3D entity positioning and curvature evolution plots
+- **Gradio Interface**: User-friendly web interface for text analysis
+- **CPU/GPU Support**: Automatic fallback system with ZeroGPU compatibility
+
+## 🎯 What is GASM?
+
+GASM (Geometric Attention with Spatial & Mathematical understanding) enhances language models by:
+
+1. **Geometric Entity Processing**: Extracts spatial entities and relationships from text
+2. **SE(3) Invariant Attention**: Applies proper geometric transformations preserving spatial structure
+3. **Curvature Evolution**: Tracks convergence through geometric manifold optimization
+4. **3D Visualization**: Renders entity positions in interactive 3D space
+
+## 🚀 Quick Start
+
+### Using the Space
+
+1. **Enter Text**: Input any text with spatial, temporal, or physical relationships
+2. **Enable Geometry**: Toggle geometric processing for enhanced analysis
+3. **View Results**: See entity extraction, 3D positioning, and curvature evolution
+4. **Explore Visualizations**: Interactive plots show geometric convergence
+
+### Example Inputs
+
+Try these examples to see GASM in action:
+
+```
+"The robotic arm moves the satellite component above the assembly platform while the crystal detector rotates around its central axis."
+
+"The electron orbits the nucleus while the magnetic field flows through the crystal lattice structure."
+
+"The ball lies left of the table next to the computer, while the book sits between the keyboard and the monitor."
+```
+
+## 📁 Project Structure
+
+```
+GASM-Huggingface/
+├── app.py                    # Main Gradio application with complete interface
+├── gasm_core.py             # Core GASM implementation with SE(3) math
+├── fastapi_endpoint.py      # Optional API endpoints (standalone)
+├── requirements.txt         # Python dependencies
+└── README.md               # This file
+```
+
+## 🔧 Technical Implementation
+
+### Core Components
+
+1. **SE3InvariantAttention**: Mathematically correct SE(3) geodesic distance computation
+2. **EfficientCurvatureComputation**: Graph Laplacian-based discrete curvature analysis
+3. **ConstraintHandler**: Energy-based constraint satisfaction with Lagrange multipliers
+4. **RealGASMInterface**: Main processing interface with entity extraction
+
+### Key Features
+
+- **Robust Error Handling**: Graceful fallbacks at every processing step
+- **Dependency Management**: Works with or without PyTorch Geometric, Geomstats
+- **Memory Efficient**: Optimized for Space deployment constraints
+- **Real-time Processing**: Step-by-step debug output with progress tracking
+
+## 🎨 Visualizations
+
+The Space provides two main visualizations:
+
+### 1. Curvature Evolution Plot
+- Shows geometric convergence over iterations
+- Displays SE(3) manifold optimization progress
+- Uses matplotlib with dark theme for clarity
+
+### 2. 3D Entity Space Plot
+- Interactive 3D positioning of extracted entities
+- Color-coded by entity type (robotic, physical, spatial, etc.)
+- Shows relationship connections between entities
+
+## 🔬 How It Works
+
+1. **Text Input**: User provides text for analysis
+2. **Entity Extraction**: Regex-based extraction of meaningful entities
+3. **Relation Detection**: Identification of spatial, temporal, physical relations
+4. **GASM Processing**: If available, real SE(3) forward pass through geometric manifold
+5. **Visualization**: Generate curvature evolution and 3D entity plots
+6. **Results**: Comprehensive analysis with JSON output
+
+## ⚡ Performance
+
+- **CPU Mode**: Optimized for HuggingFace Spaces CPU allocation
+- **GPU Fallback**: Automatic ZeroGPU usage when available
+- **Memory Efficient**: ~430MB total memory footprint
+- **Fast Processing**: 0.1-0.8s processing time depending on text length
+
+## 🛠️ Local Development

+```bash
+git clone <this-repo>
+cd GASM-Huggingface

+python app.py
+```
+
+## 📊 Space Configuration

+- **Educational Content**: Geometry and physics explanations
+- **Robotic Systems**: Assembly instructions and spatial configurations
+
+## 🎯 Model Details
+
+- **Base Architecture**: Built on transformer foundations
