Data stream mining Wikipedia

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. In many data stream mining applications, the goal is to predict the class or value of new instances in th

Mining Stream, Time-Series, and Sequence Data

2013-06-18· 470 Chapter 8 Mining Stream, Time-Series, and Sequence Data A technique called reservoir sampling can be used to select an unbiased random sample of s elements without replacement. The idea behind reservoir sampling is rel-atively simple. We maintain a sample of size at least s, called the “reservoir,” from which a random sample of size s can be generated.

Introduction to Stream Mining Towards Data Science

Data stream management system. Adapted from de.wikipedia.org. Next, is discussed how to analyse Data Streams.Data-Based Techniques rely on analysing a representative subset of data [3, 9]. This techniques also are used as preprocessing for Data Stream algorithms. On the Other Hand, Mining Techniques are enhanced versions of traditional Data Mining Algorithms.
