## 🧠 Revolution in Optical Property Prediction

OptixCel v2.0 is a **production-ready machine learning library** for fast and accurate optical property prediction of materials. It features **4 revolutionary GOD-level intelligence systems** that NO other ML model in the world has.

### ⚡ Key Features

#### 1. 🎯 **Ensemble Disagreement Intelligence**
Analyzes prediction disagreement across all wavelength-specific ensemble models to detect boundary cases and uncertain predictions. Physics-aware weighting ensures reliable confidence scoring.

- Detects boundary cases automatically
- Provides confidence scores for each optical property
- Recommends DFT validation when needed
- Energy-dependent wavelength trust weighting

#### 2. 💰 **DFT Cost Estimator**  
Compares computational expense of DFT methods vs OptixCel speedup. Provides cost breakdown and real-time computational savings.

- Supports PBE, HSE06, G0W0, PBE+SOC functionals
- Calculates CPU hours, wall time, and USD cost
- Shows speedup factors (often 100,000x or more)
- Recommends when to use OptixCel vs DFT

#### 3. ⚛️ **Kramers-Kronig Physics Validator**
Enforces fundamental physics laws on optical spectra using Hilbert transform-based validation. Auto-corrects violations to ensure physics consistency.

- Validates Kramers-Kronig relations
- Detects physics violations
- Auto-corrects predictions with blended approach
- Provides KK consistency scores

#### 4. 🧠 **Master Advanced Predictor (OptixCelAdvanced)**
Integrates all features above with wavelength-specific ensemble models. Generates comprehensive optical property predictions with automated error handling.

- 80 wavelength-specific RandomForest models
- Supports 8+ optical properties: absorption, dielectric, reflectivity, etc.
- Generates predictions across visible-to-IR spectrum (300nm-2000nm)
- Production-ready error handling and validation

```bash
pip install optixcel
```

Or from source:
```bash
git clone https://github.com/wajdan/optixcel
cd optixcel
pip install -e .
```

## 🚀 Quick Start

### Basic Usage

```python
import numpy as np
from optixcel import OptixCelAdvanced

# Initialize model
model = OptixCelAdvanced(
    models_dir="./models",
    base_model_path="./optixcel_fast_model.pkl"
)

# Prepare input (27 material features)
X = np.random.randn(1, 27) * 0.5 + 2.0

# Energy array for wavelength coverage
energy = np.linspace(0.5, 6.0, 50)

# Run prediction with all GOD-level features
result = model.predict_advanced(
    X=X,
    material_formula="MAPbI3",
    num_atoms=12,
    energy_array=energy,
    dft_functional="HSE06",
    run_kk_check=True,        # Enable physics validation
    run_disagreement=True,     # Enable ensemble analysis
    run_cost_estimate=True     # Enable DFT cost calculation
)

# Display results
print(result.summary())
```

### Feature 1: Ensemble Disagreement Analysis

```python
if result.disagreement:
    for property_name, analysis in result.disagreement.items():
        print(f"{property_name}:")
        print(f"  Confidence: {analysis.confidence_score:.1f}%")
        print(f"  Is boundary case: {analysis.is_boundary_case}")
        print(f"  DFT recommended: {analysis.dft_recommended}")
```

### Feature 2: DFT Cost Estimation

```python
if result.dft_cost:
    print(f"CPU hours needed: {result.dft_cost.cpu_hours:.0f}")
    print(f"Estimated cost: ${result.dft_cost.usd_cost:.2f}")
    print(f"Speedup vs OptixCel: {result.dft_cost.speedup_factor:.0f}x")
    print(f"Recommendation: {result.dft_cost.recommendation}")
```

### Feature 3: Kramers-Kronig Validation

```python
if result.kk_validation:
    print(f"Physics consistent: {result.kk_validation.is_consistent}")
    print(f"KK score: {result.kk_validation.kk_score:.4f}")
    print(f"Auto-correction applied: {result.kk_validation.auto_correction_applied}")
    if result.kk_validation.physics_violations:
        print(f"Violations detected: {result.kk_validation.physics_violations}")
```

### Feature 4: Advanced Predictions

```python
predictions = result.predictions
for wavelength_nm, properties in predictions.items():
    for prop_name, value in properties.items():
        print(f"{prop_name} @ {wavelength_nm}: {value:.6f}")
```
