  • Aim: develop a demo showing a full spectrum of Pentaho capabilities

  • 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)

  • Collecting, Preparing and Blending

  • Demonstration

  • Collecting, Preparing and Blending

  • Air Quality Prediction

  • Pentaho Machine Learning Orchestration

    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

    What we covered today:

    • Pentaho provides a single consistent experience for developing data products • The platform allows to put machine learning algorithms into production • Informative dashboards for decision making based on advanced analytics and data transformation in the backend
