Question

Concept hierarchies define a sequence of mappings from more general concepts and can be represented as a set of nodes organiz a lattice, or as a partial order. They are useful in data mining because knowledge at multiple levels of abstraction and provide the structure on wl (rolled-up) or specialized (drilled-down). Together, these operations allow different perspectives, gaining further insight into relationships hidden in the advantage of compressing the data set, and mining on a compressed da operations. This will be more efficient than mining on a large, uncompres set of lower-le Recent applications pay special attention to spatiotemporal data streams. A contains spatial information that changes over time, and is in the form o flow in-and-out like possibly infinite streams. (a) Present three application examples of spatiotemporal data streams. (b) Discuss what kind of interesting knowledge can be mined from such time and resources. (c) Identify and discuss the major challenges in spatiotemporal data min (d) Using one application example, sketch a method to mine one kind of data efficiently. Answer: New question. Answer needs to be worked out. I
