BACKGROUND According to [Li H. F. et al, 2006], data streams are further The Micro-clustering Based Stream Mining Framework 12 3. Algorithms written for data streams can naturally cope with data sizes many times greater than memory, and can extend to challenging real-time applications not previously tackled by machine learning or data min-ing. Stream 9 Querying Stream mining is a more challenging task in many cases It shares most of the difficulties with stream querying But often requires less “precision”, e.g., no join, grouping, sorting Patterns are hidden and more general than querying It may require exploratory analysis, not necessarily continuous queries Summary –Stream Mining Important tools for stream mining Sampling from Data Stream (Reservoir Sampling) Querying Over Sliding Windows (DGIM method for counting the number of 1s or sums in the window) Filtering a Data Stream (Bloom Filter) Counting Distinct Elements (Flajolet-Martin) Estimating Moments (AMS method; surprise number) Mining Data Streams 7 • More algorithms for streams: • (1) Filtering a data stream: Bloom filters • Select elements with property x from stream • (2) Counting distinct elements: Flajolet-Martin • Number of distinct elements in the last k elements of the stream • (3) Estimating moments: AMS method • Estimate std.

Mining Time-Changing Data Streams Geoff Hulten Dept. Accelerated PSO Swarm Search Feature Selection for Data Stream Mining Big Data Abstract: Big Data though it is a hype up-springing many technical challenges that confront both academic research communities and commercial IT deployment, the root sources of Big Data are founded on data streams and the curse of dimensionality. Web companies, such as Yahoo!, need to obtain useful information from big data streams, i.e. of Computer Science and Engineering University of Washington Box 352350 Seattle, WA 98195, U.S.A. ghulten@cs.washington.edu Laurie Spencer Innovation Next 1107 NE 45th St. #427 Seattle, WA 98105, U.S.A lauries@innovation-next.com Pedro Domingos Dept. Generally there is only a single chance to see the data. When a user joins the system, we have no idea about the user’s profile, and thus we start to provide all news topics to the user. Our objective is to present to the community a position paper that could inspire and guide future research in data streams. data mining process, the data to be mined is assumed to have been loaded into a stable, infrequently-updated database, and mining it can then take weeks or months, after which the results are deployed and a new cycle begins. discriminative items 1 Introduction We want to build a personalized news delivery service. The fundamental processes generating most real-world data streams may change over years, months and even seconds, at times drastically. 1. 4.4-4.7) Colab 8 out: Colab 7 due: Tue Mar 3: Computational Advertising : Suggested Readings: Such data sets which continuously and rapidly grow over time are referred to as data streams.
