# Engine Predictive Maintenance — XGBoost Classifier
|
| 11 |
+
|
| 12 |
+
Binary classifier predicting whether an engine requires maintenance (`engine_condition = 1`)
|
| 13 |
+
based on six sensor readings (RPM, lub-oil pressure/temp, fuel pressure,
|
| 14 |
+
coolant pressure/temp).
|
| 15 |
+
|
| 16 |
+
## Usage
|
| 17 |
+
|
| 18 |
+
```python
|
| 19 |
+
import joblib, pandas as pd
|
| 20 |
+
from huggingface_hub import hf_hub_download
|
| 21 |
+
|
| 22 |
+
path = hf_hub_download(repo_id="debasishdas1985/engine-predictive-maintenance-model", filename="best_engine_model.joblib")
|
| 23 |
+
model = joblib.load(path)
|
| 24 |
+
sample = pd.DataFrame([{
|
| 25 |
+
"engine_rpm": 700, "lub_oil_pressure": 2.5, "fuel_pressure": 11.8,
|
| 26 |
+
"coolant_pressure": 3.2, "lub_oil_temp": 84.1, "coolant_temp": 81.6,
|
| 27 |
+
}])
|
| 28 |
+
print(model.predict(sample), model.predict_proba(sample))
|
| 29 |
+
```
|
| 30 |
+
|
| 31 |
+
