# hvac-ml-dataset-fun
This is a hobby project focused on analyzing a historical dataset from a medium-sized office HVAC system. The goal is to explore fitting machine learning models for fun while studying electrical load-shifting strategies and potentially delving into reinforcement learning.
**⚠️👷🚧🏗️ WARNING** - This is a highly experimental hobby project!
# Model Fitting and Evaluation for Time-Series Dataset
This document describes the process of training and evaluating several regression models using Scikit-Learn on a time-series dataset. The dataset includes the following features:
### Dataset Features (Excerpt from `df.describe()`)
| Feature Name | Count | Mean | Std Dev | Min | 25% | 50% | 75% | Max |
|----------------------|---------|--------|---------|-------|-------|-------|-------|--------|
| `HWR_value` | 84750 | 98.68 | 30.35 | 62.55 | 73.56 | 83.44 | 126.36| 178.16 |
| `CWS_Temp` | 84750 | 57.19 | 11.03 | 0.00 | 47.14 | 56.40 | 66.83 | 91.04 |
| `Ra_Temp` | 84750 | 69.52 | 2.81 | 0.00 | 67.93 | 69.08 | 70.74 | 83.60 |
| `EaDamper` | 84750 | 14.65 | 18.94 | 0.00 | 0.00 | 10.00 | 20.00 | 100.00 |
| `VAV2_6_SpaceTemp` | 84750 | 69.61 | 2.77 | 0.00 | 67.69 | 70.60 | 71.72 | 75.06 |
**Note**: The full dataset contains 38 features and approximately 84,750 rows.

## Training and Evaluation Process
1. **Data Preprocessing**:
- The dataset was filtered to include only data from 2024.
- Unnecessary HVAC setpoint columns (`timestamp`, `CWS_Freeze_SPt`, `Eff_DaSPt`, `EffSetpoint`, `SaTempSPt`, `CurrentKWHrs`) were dropped.
- A specific date (`2024-08-03`) was removed for future testing and saved as a separate file.
2. **Models and Hyperparameter Tuning**:
The following models were trained using a randomized grid search with 3-fold cross-validation:
- **Cat Boost**
- **Extra Trees**
- **Decision Tree**
- **K-Neighbors**
- **Random Forest**
- **AdaBoost**
- **Gradient Boosting**
3. **Metrics**:
The performance of each model was evaluated using Mean Squared Error (MSE) on the test set. Best-fit parameters and MSE values were recorded for each model.
4. **Model Saving**:
- The best-fit model for each type was saved as a `.pkl` file.
- Results were saved as `.txt` and `.json` files for each model.
