Data Mining and Knowledge Discovery Handbook, 2 Edition part 20. Knowledge Discovery demonstrates intelligent computing at its best, and is the most desirable and interesting end-product of Information Technology. To be able to discover and to extract knowledge from data is a task that many researchers and practitioners are endeavoring to accomplish. There is a lot of hidden knowledge waiting to be discovered – this is the challenge created by today’s abundance of data. Data Mining and Knowledge Discovery Handbook, 2nd Edition organizes the most current concepts, theories, standards, methodologies, trends, challenges and applications of data mining (DM) and knowledge discovery. | 170 Lior Rokach and Oded Maimon such as supervised learning lr6 lr12 lr15 unsupervised learning Ir13 lr8 lr5 lr16 and genetic algorithms lr17 lr11 lr1 lr4.
