Data Mining and KDD: A Shifting Mosaic
نویسنده
چکیده
Data Mining is an idea based on a simple analogy. The growth of data warehousing has created mountains of data. The mountains represent a valuable resource to the enterprise. But to extract value from these data mountains, we must "mine" for high-grade "nuggets" of precious metal -the gold in data warehouses and data marts. The analogy to mining has proven seductive for business. Everywhere there are data warehouses, data mines are also being enthusiastically constructed, but not with the benefit of consensus about what data mining is, or what process it entails, or what exactly its outcomes (the "nuggets") are, or what tools one needs to do it right.

متن کاملOptimal Knowledge Refreshing Policies for the KDD Process
Knowledge Discovery in Databases (KDD) provides organizations necessary tools to sift through vast data stores to extract knowledge, which supports and improves organizational decision making. Most of the prior KDD research assumed that data are static, and focused on either the efficiency of the KDD process (e.g., designing more efficient data mining algorithms) or identifying new applications...
متن کاملReducing Data Stream Sliding Windows by Cyclic Tree-Like Histograms
Data reduction is a basic step in a KDD process useful for delivering to successive stages more concise and meaningful data. When mining is applied to data streams, that are continuous data flows, the issue of suitably reducing them is highly interesting, in order to arrange effective approaches requiring multiple scans on data, that, in such a way, may be performed over one or more reduced sli...

INTRODUCTION The KDD Cup is the oldest of the many data mining competitions that are now popular [1]. It is an integral part of the annual ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD). In 2007, the traditional KDD Cup competition was augmented with a workshop with a focus on the concurrently active Netflix Prize competition [2]. The KDD Cup itself in 2007 con...
