Problems and Challenges in Data Mining

  Data mining systems face a lot of problems and pitfalls. A system which is quick and correct on some small training sets, could behave completely different when applied to a larger database. A data mining system may work perfect for consistent data and perform significant worse when a little noise is added to the training set. In this section we take a look at what we mean are the most prominent problems and challenges of data mining systems today.

• Noisy Data
• Difficult Training Set
• Databases are Dynamic
• Databases may be Huge
