|3rd International Workshop on
Knowledge Discovery from Sensor Data
|Held in conjunction with|
For this inaugural SensorKDD Challenge, held in conjunction with the 3rd Workshop on Knowledge Discovery from Sensor Data (SensorKDD-2009), 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 daily global air temperature and precipitation measurements for a 50-year period (1950-1999).
Your task is to detect significant changes in this data. Note that “change” in this context may be an abrupt change (i.e., an anomaly or outlier), a gradual change (i.e., a shift in distribution), an extreme event (i.e. heat wave, severe rainfall, drought) or something different altogether. We intentionally omit a precise definition here to invite creative problem definitions and solutions.
The data consists of daily global air temperature and precipitation measurements, aggregated from heterogeneous sensors, for the period from 1950-1999 (see  for details). This data is also publicly available for download, for example from  or  (registration may be required).
Two options are available for downloading the data.
We invite the submission of manuscripts addressing this challenge task following the format of the SensorKDD-2009 Workshop (maximum 9 pages, ACM standard format). Please include your definition of “change”. Entries will be evaluated subjectively based on their methodology and validation strategy.
Best Challenge Entry Award.
