Timestamps • Each bit in the stream has a timestamp, starting 1, 2, … • Record timestamps modulo N (the window size), so we can represent any relevant timestamp in O(log2N ) bits. • E.g., we are processing 1 billion streams and N = 1 billion, but we’re happy with an approximate answer. • Can we handle the case where the stream is not bits, but integers, and we want the sum of the last k ? supervised vs. unsupervised learning. As this thesis concentrates on classiﬁcation techniques, we will use the term data stream learning as a synonym for data stream mining. 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. • Add in half the size of the last bucket. non-stationary (the distribution changes over time) This page contains Data Mining Seminar and PPT with pdf report.

Data stream mining is a strategy that involves identifying and extracting information from an active data stream. Download slides (PPT) in French: Chapter 4, Chapter 5, Chapter 8, Chapter 9, Chapter 10. We are facing two challenges, the overwhelming volume and the concept drifts of the streaming data. 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..

Mining data streams is concerned with extracting knowledge structures represented in models and patterns in non stopping streams of information. Cs 361a (advanced algorithms). • Buckets disappear when their end-time is > N time units in the past. • When new bit comes in, discard the N +1st bit. Google wants to know what queries are more frequent today than yesterday.

Knowledge discovery from infinite data streams is an important and difficult task. basic concepts and a road, DATA MINING van data naar informatie Ronald Westra Dep. Buckets • A bucket in the DGIM method is a record consisting of: • The timestamp of its end [O(log N ) bits]. Mining click streams. Data mining technique helps companies to get knowledge-based information. Updating Buckets --- (2) • If the current bit is 1: • Create a new bucket of size 1, for just this bit. Data enters at a rapid rate from one or more input ports. • Interesting case: N is still so large that it cannot be stored on disk. • Real Problem: what if we cannot afford to store N bits?
