Our Use Case “London Air Quality Monitoring”

Why?

• Air quality affects well-being of residents and visitors of the city
• 9000 early deaths a year in London due to air pollution
• Air pollution monitoring and mitigation are crucial for city councils
• The use case is easy to understand and to follow

Data Sources

• London Air Quality Network (96 stations across the city)
• Road Traffic Counts (number and vehicle type)
• Meteorological Parameters (wind, temperature, humidity)

Air Quality Prediction

Pentaho Machine Learning Orchestration

1 2 4 3 1 Predictive model for Air Quality was added to the demo. *Long-Short Term Memory neural network was used to make predictions

Demonstration

Operationalising Predictive Model in Pentaho

What we have shown in the demo:

• Feature engineering and data preparation
• Scheduled model training and update
• Model application on new data streams
• Tracking and storing model performance metrics
• Displaying predictions in Pentaho dashboards

Operationalize machine learning models in Pentaho!

Summary
