The 7 Most Important Data Mining Techniques - Data

2017-12-22  Data mining is the process of looking at large banks of information to generate new information. Intuitively, you might think that data “mining” refers to the extraction of new data, but this isn’t the case; instead, data mining is about extrapolating patterns and new knowledge from the data you’ve already collected.

Anomaly detection identifies data points atypical of a given distribution. In other words, it finds the outliers. Though simpler data analysis techniques than full-scale data mining can identify outliers, data mining anomaly detection techniques identify much more subtle attribute patterns and the data points that fail to conform to those patterns.

Data Mining — Handling Missing Values the Database

2009-8-14  I’ve recently answered Predicting missing data values in a database on StackOverflow and thought it deserved a mention on DeveloperZen.. One of the important stages of data mining is preprocessing, where we prepare the data for mining. Real-world data tends to be incomplete, noisy, and inconsistent and an important task when preprocessing the data is to fill in missing values, smooth out ...

Data Mining MCQ (Multiple Choice Questions) -

Answer: c Explanation: In some data mining operations where it is not clear what kind of pattern needed to find, here the user can guide the data mining process. Because a user has a good sense of which type of pattern he wants to find. So, he can eliminate the discovery of all other non-required patterns and focus the process to find only the required pattern by setting up some rules.
