Something That Doesn’t (Quite) Work • Summarize exponentially increasing regions of the stream, looking backward. 2 of size 8 2 of size 4 1 of size 2 2 of size 1 N. Updating Buckets --- (1) • When a new bit comes in, drop the last (oldest) bucket if its end-time is prior to N time units before the current time. First, it is unrealistic to keep the entire stream in the main memory or even in a secondary storage area, since a data stream comes continuously and the amount of data is unbounded. Data Stream Mining (also known as stream learning) is the process of extracting knowledge structures from continuous, rapid data records.A data stream is an ordered sequence of instances that in many applications of data stream mining can be read only once or a small number of times using limited computing and storage capabilities.. Data Stream Mining George Tzinos 2. Mining data streams is concerned with extracting knowledge structures represented in models and patterns in non stopping streams of information. Updating Buckets --- (2) • If the current bit is 1: • Create a new bucket of size 1, for just this bit. Data lecture notes for Chapter 4 - 5 introduction to data, we don t.
