Detailed explanation-1: -KDD refers to the overall process of discovering useful knowledge from data. It involves the evaluation and possibly interpretation of the patterns to make the decision of what qualifies as knowledge.
Detailed explanation-2: -We define the KDD process [4] as: The nontrivial process of identifying valid, novel, potentially useful, and ultimately understandable patterns in data. Throughout this article, the term pattern goes beyond its traditional sense to include models or structure in data.
Detailed explanation-3: -KDD is the systematic process of identifying valid, practical, and understandable patterns in massive and complicated data sets. The base of the KDD method is data mining, which involves the inference of algorithms that analyze the data, build the model, and discover previously unknown patterns.
Detailed explanation-4: -Abstract: Knowledge Discovery in Databases (KDD) is the process of automatic discovery of previously unknown patterns, rules, and other regular contents implicitly present in large volumes of data. Data Mining (DM) denotes discovery of patterns in a data set previously prepared in a specific way.
Detailed explanation-5: -Answer: 4. Knowledge discovery database. Explanation: in the data mining process, KDD stands for Knowledge discovery database.
