since we can’t store the entire stream one obvious approach is to store a sample two different problems: sample a fixed proportion of elements in the stream (say 1 in 10) maintain a random sample of fixed size over a potentially infinite stream 2/16/2010 jure leskovec & anand rajaraman stanford cs345a: data mining 8

chapter 8 time series data mining. times series data mining is an emerging field that holds great opport unities for conversion of data into information. it is intuitively obvious to us that the world is filled with time series data—actually transactional data—such as point-of-sales (pos) data financial (stock market) data and web site data.
mining real-world time series and streaming data creates a need for new technologies and algorithms which are still being developed and tested by data scientists worldwide. the purpose of this volume is to present the most recent advances in pre-processing mining and utilization of streaming data that is generated by modern information systems.

in this chapter you will learn how to write mining codes for stream data time-series data and sequence data. the characteristics of stream time-series and sequence data are unique that is large and endless. it is too large to get an exact result; this means an approximate result will be achieved.
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
