Knowledge Discovery in Databases (KDD) is the non-trivial extraction of implicit, previously unknown and potentially useful knowledge from data. • Data mining is the exploration and analysis of large quantities of data in order to discover valid, novel, potentially useful, and ultimately understandable patterns in data. Process
Knowledge Discovery in Databases (KDD) is an automatic, exploratory analysis and modeling of large data repositories. KDD is the organized process of identifying valid, novel, useful, and understandable patterns from large and complex data sets. Data Mining (DM) is the core of the KDD process, involv- ing the inferring

2. The Knowledge Discovery Process. In this Chapter, we describe the knowledge discovery process, present some models, and explain why and how these could be used for a successful data mining project. 1. Introduction. Before one attempts to extract useful knowledge from data, it is important to understand the.
1 Jan 2009 Introduction. The number of applied in the data mining and knowledge discovery (DM & KD) projects has increased enormously over the past few years (Jaffarian et al., 2008) (Kdnuggets.com,. 2007c). As DM & KD development projects became more complex, a number of problems emerged: continuous
