Mining Data Streams - Stanford University

Chapter 4 Mining Data Streams Most of the algorithms described in this book assume that we are mining a database. That is, all our data is available when and if we want it. In this chapter, we shall make another assumption: data arrivesin a stream or streams, and if it is not processed immediately or stored, then it is lost forever. Moreover,

Data stream mining - Wikipedia

Data Stream Mining 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 …

with data sizes many times greater than memory, and can extend to chal-lenging real-time applications not previously tackled by machine learning or data mining. The core assumption of data stream processing is that train-ing examples can be briefly inspected a single time only, that is, they arrive
