Data Mining

Recent applications pay special attention to spatiotemporal data streams. A spatiotemporal data stream contains spatial information that changes over time and is in the form of stream data, i.e., the data flow in-and-out like possibly infinite streams. 1. Give three application examples of spatiotemporal data streams. 2. Discuss what kind of interesting knowledge can be mined from such data streams, with limited time and resources. 3. Identify and discuss the major challenges in spatiotemporal data mining. 4. Using one application example, sketch a method to mine one kind of knowledge from such stream data efficiently
