Learn about the concepts involved in data mining, the process of discovering actional information in large sets of data.
Data mining is the process of discovering actionable information from large sets of data. Data mining uses mathematical analysis to derive patterns and trends that exist in data. Typically, these patterns cannot be discovered by traditional data exploration because the relationships are too complex or ...
Data Mining introduces in clear and simple ways how to use existing data mining methods to obtain effective solutions for a variety of management and engineering design problems. Data Mining is organised into two parts: the first provides a focused introduction to data mining and the second goes ...
obtaining a small sample s to represent the whole data set N Allow a mining algorithm to run in complexity that is potentially sub-linear to the size of the data Key principle: Choose a representative subset of the data Simple random sampling may have very poor performance in the presence of...
pattern mining中的pattern多被译成“模式”。 听着实在觉得别扭,死板。 pattern, sth that repeats in a predictable way is a pattern. from wiki: Data miningis the process ofdiscovering patternsin large data sets involving methods at the intersection of machine learning, statistics and database systems...

also provides a number of Review Questions and Problems at the end of each chapter.These should be very helpful for adopters and students alike.In fact,this book may encourage instructors to develop a new course in data mining at the upper undergraduate or at the entry graduate level in ...

Datamining Concepts Use case:ause caseis a list of steps, typically defining interactions between a role (known inUMLas an "actor") and a system, to achieve a goal. The actor can be a human or an external system. e.g. Stemming: In linguisticmorphology and information retrieval, stemming...
