We need to have a huge data set of past values to predict future trends. These outliers may be valuable associations in many applications, although they are usually discarded as noise. Data Mining Functionalities – Frequent sequential patterns: such as the pattern that customers tend to purchase first a PC, followed by a digital camera, and then a memory card, is a (frequent) sequential pattern. Evolution Analysis Discrimination 3. Data mining tasks classified into two categories: descriptive and predictive. If the class label is missing, then the prediction is done using classification. Functionalities Of Data Mining - Here are the Data Mining Functionalities and variety of knowledge they discover.Characterization, Discrimination, Association Analysis, Classification, … The generalized data is presented in various forms like tables, pie charts, line charts, bar charts, and graphs. Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems. It means the data mining system is classified on the basis of functionalities such as − 1. Descriptive mining tasks characterize the general properties of the data in the database. When data that cannot be grouped in any of the class appears, we use outlier analysis. For example, that is if mobile phones are bought with headphones: support is 2% and confidence is 40%. The outliers are identified using statistical tests that find the probability. The multi-dimensional relationship between the data is presented in a rule called characteristics rule of the target class. By and large, there are two types of data mining tasks: descriptive data mining tasks that describe the general properties of the existing data, and predictive data mining tasks that attempt to do predictions based on inference on available data. Data mining : Data mining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and … Generally, data mining is categorized as: Data is associated with classes or concepts so they can be correlated with results.
