## POI Feature Integration
|
||||
|
||||
### How POI Features Improve Predictions
|
||||
|
||||
The Forecasting Service uses location-based POI features to enhance prediction accuracy:
|
||||
|
||||
**POI Feature Usage:**
|
||||
```python
|
||||
from app.services.poi_feature_service import POIFeatureService
|
||||
|
||||
# Initialize POI service
|
||||
poi_service = POIFeatureService(external_service_url)
|
||||
|
||||
# Fetch POI features for tenant
|
||||
poi_features = await poi_service.fetch_poi_features(tenant_id)
|
||||
|
||||
# POI features used in predictions:
|
||||
# - school_density → Higher breakfast demand on school days
|
||||
# - office_density → Lunchtime demand spike in business areas
|
||||
# - transport_hub_proximity → Morning/evening commuter demand
|
||||
# - competitor_proximity → Market share adjustments
|
||||
# - residential_density → Weekend and evening demand patterns
|
||||
# - And 13+ more features
|
||||
```
|
||||
|
||||
**Impact on Predictions:**
|
||||
- **Location-Aware Forecasts** - Predictions account for bakery's specific location context
|
||||
- **Consistent Features** - Same POI features used in training and prediction ensure consistency
|
||||
- **Competitive Intelligence** - Adjust forecasts based on nearby competitor density
|
||||
- **Customer Segmentation** - Different demand patterns for residential vs commercial areas
|
||||
- **Accuracy Improvement** - POI features contribute 5-10% accuracy improvement
|
||||
|
||||
**Endpoint Used:**
|
||||
- `GET {EXTERNAL_SERVICE_URL}/poi-context/{tenant_id}` - Fetch POI features
|
||||
|
||||
## Integration Points
|
||||
|
||||
