Detailed explanation-1: -To answer the first question, a pattern is interesting if it is (1) easily understood by humans, (2) valid on new or test data with some degree of certainty, (3) potentially useful, and (4) novel. A pattern is also interesting if it validates a hypothesis that the user. An interesting pattern represents knowledge.
Detailed explanation-2: -Pattern evaluation We identify and segregate the truly interesting patterns representing knowledge based on interestingness measures.
Detailed explanation-3: -For example, metrics such as support, confidence, lift, correlation, and collective strength are often used to determine the interestingness of association patterns.
Detailed explanation-4: -Data mining represents one step in the process of ‘knowledge discovery in databases’ (KDD), where the latter may be defined as “the nontrivial process of identifying valid, novel, potentially useful, and ultimately understandable patterns in data” (Helma et al.
Detailed explanation-5: -Data mining, also known as knowledge discovery in data (KDD), is the process of uncovering patterns and other valuable information from large data sets.
