International Workshop on Knowledge
To be held in conjunction with
August 12, 2012
For the second SensorKDD Challenge, to be held in conjunction with the 6th Workshop on Knowledge Discovery from Sensor Data (SensorKDD-2012), we pose a general and open-ended problem related to the workshop theme Climate Change, Energy Assurance, and Infrastructural Impacts. Specifically, we focus on the first component and provide a large climate dataset consisting of both model simulated and observed precipitation for a period of time.
Your task is to detect significant trends in the precipitation extremes. Note that the notion of extremes is open to interpretation and you are free to consider multiple indicator of extremes. We omit a precise definition here to invite creative problem definitions and solutions.
Following is a short description of the model simulated and observed data.
We invite the submission of manuscripts addressing this challenge task following the format of the SensorKDD-2012 Workshop (maximum 9 pages, ACM standard format). Please include your definition of extremes. Entries will be evaluated subjectively based on their methodology and validation strategy. The deadline for submission is 30th May. Please email your submission to Sensorkdd2012@gmail.com with a subject "SensorKDD Challenge" and include your name, affiliations and contact details.
Best Challenge Entry Award.
