  1. Eran Chinthaka & Jaliya Ekanayake Class Project for: Knowledge Based Computing (B552) CBR Approach FOR efficient execution of Workflows: Applied to Weather Data

  2. Current System Rule Engine 1 2 R 3 4 Workflows Predictions

  3. Our Approach CBR 1 2 Window of Events Cases 3 4 Workflows Predictions

  4. Challenges • Weather events are in special formats. • Mostly spatial data • Similarity checking can be difficult • Events arrive at higher rates • 145 events each 4xx KB for every 5 mins • Pre-filtering • Window size • Small -> Higher performance cost • Large -> Slower prediction • Need to out perform a rule based system.
