## 🏆 Supported Thermodynamic Properties

Thermoverse predicts the following thermodynamic targets:

✅ **Debye Temperature** (K) - Material's characteristic thermal energy scale  
✅ **Enthalpy of Formation** (eV) - Energy required to form the compound  
✅ **Thermal Expansion Coefficient** (K⁻¹) - How material expands with temperature  
✅ **Heat Capacity** (J/mol·K) - Energy needed to raise temperature  
✅ **Thermal Conductivity** (W/m·K) - Heat transfer capability  
✅ **Entropy** (J/mol·K) - Disorder/randomness in structure  
✅ **Free Energy** (eV) - Thermodynamic stability indicator  

### 🔬 What is Thermodynamics?

**Thermodynamics** is the branch of physics that studies heat, energy, and equilibrium in materials. Thermodynamic properties are critical for:

- **Materials Screening**: Identify stable compounds before synthesis
- **Energy Applications**: Predict thermal efficiency and conductivity
- **Device Design**: Optimize materials for specific thermal behavior
- **Phase Stability**: Understand at what temperatures materials exist
- **Manufacturing**: Predict behavior during processing and heating

### 📊 Physical Significance of Key Properties

| Property | Symbol | Unit | What It Means | Why It Matters |
|----------|--------|------|---------------|----------------|
| **Debye Temperature** | θD | K | Max phonon frequency | Predicts heat capacity & stability |
| **Enthalpy Formation** | ΔHf | eV | Formation energy | Compound stability & synthesizability |
| **Thermal Expansion** | α | K⁻¹ | Size change with T | Device design & thermal stress |
| **Heat Capacity** | Cp | J/mol·K | Energy to heat | Thermal mass & cooling requirements |
| **Thermal Conductivity** | κ | W/m·K | Heat flow rate | Insulation & cooling applications |
| **Entropy** | S | J/mol·K | Disorder level | Phase transitions & equilibrium |
| **Free Energy** | G | eV | Stability potential | Spontaneity of reactions |

### 🧮 Thermodynamic Relationships

Thermoverse predicts properties that follow fundamental thermodynamic laws:

```
First Law:    ΔU = Q - W  (Energy conservation)
               
Second Law:   ΔS ≥ Q/T   (Entropy increases)
               
Gibbs Energy: G = H - TS  (Predicts spontaneity)
               
Heat Capacity: Cp = (∂H/∂T)p  (Temperature response)
```

These relationships are embedded in Thermoverse's training pipeline, enabling accurate predictions across different compositions.  

## 🧠 Advanced Model Architecture

Thermoverse uses a **sophisticated ensemble hybrid pipeline** specifically designed for thermodynamic property prediction:

```
Material Composition Input (125 features)
    ↓
    │ Element fractions, lattice parameters,
    │ electronegativity, atomic radii, etc.
    ↓
[Stage 1] Feature Engineering & Scaling
    ├─ Robust scaling to [-1, 1]
    ├─ Outlier detection & handling
    └─ Feature cross-products & interactions
    ↓
[Stage 2] Random Forest Feature Selection
    ├─ Identify top 80 most important features
    ├─ Remove noise & redundant features
    └─ Reduce dimensionality & training time
    ↓
[Stage 3] Ensemble Predictions (Parallel)
    ├─ XGBoost Model (gradient boosting)
    │   └─ Optimal for non-linear relationships
    ├─ LightGBM Model (fast gradient boosting)
    │   └─ Efficient on large datasets
    └─ Random Forest Model (bagging)
        └─ Robust to outliers & stable
    ↓

    ├─ Average predictions from 3 models
    ├─ Calculate confidence interval
    └─ Apply domain-specific constraints
    ↓
Thermodynamic Property Prediction (Output)
```

### 🔧 Model Architecture Details

**Stage 1: Feature Engineering**
- Input: 125 composition & structure features
- Processing:
  - StandardScaler for numerical stability
  - Handling missing values via imputation
  - Feature interaction engineering (selected pairs)
- Output: Normalized feature vectors

**Stage 2: Feature Selection via Random Forest**
- Algorithm: Mean Decrease Impurity (MDI)
- Selection: Top 80 features by importance
- Benefit: Reduces noise, speeds up training, improves generalization
- Output: Reduced feature set with highest signal

**Stage 3: Ensemble Predictions**

| Model | Algorithm | Parameters | Strength |
|-------|-----------|-----------|----------|
| **XGBoost** | Gradient Boosting | n_estimators=200, max_depth=8 | Captures complex non-linear patterns |
| **LightGBM** | Fast Gradient Boosting | n_estimators=200, num_leaves=50 | Efficient training, handles large datasets |
| **Random Forest** | Bootstrap Aggregating | n_estimators=300, max_depth=15 | Robust to outliers, stable predictions |

Each model trains independently in parallel, then predictions are merged.

**Stage 4: Prediction Aggregation**
```python
final_prediction = (xgb_pred + lgbm_pred + rf_pred) / 3
uncertainty = std([xgb_pred, lgbm_pred, rf_pred])
confidence_lower = final_prediction - 1.96 * uncertainty
confidence_upper = final_prediction + 1.96 * uncertainty
```

### 🎯 Why This Architecture Works for Thermodynamics

1. **Ensemble Robustness**: Combining 3 models reduces overfitting risk
2. **Feature Importance**: RF selection removes noisy features
3. **Non-Linear Relationships**: Captures complex thermodynamic behaviors
4. **Cross-Material Generalization**: Tested on 181K diverse materials
5. **Interpretability**: SHAP explains each prediction
6. **Physical Constraints**: Output validated against thermodynamic laws

- Model types: Ensemble models (XGBoost / CatBoost / RandomForest-style) trained per-property with cross-validation and ensembling.
- Inputs: Composition-based features and engineered descriptors produced by preprocessing scripts.
- Outputs: Per-property CSV predictions under `outputs/` and evaluation summaries (R², RMSE) stored in `outputs/` and `models/`.
- Usage: create a Python environment, install dependencies, then run training and evaluation scripts such as `python train_181600_models.py`.
- Notes: large model files and outputs are excluded via `.gitignore`. If datasets or model artifacts exceed GitHub file size limits (>100MB) enable Git LFS for those paths.
