DATA MINING PRIMITIVES Presented by M.LAVANYA MSc(CS&IT) Nadar saraswathi college of arts & science Theni. • Having a data mining query language provides a foundation on which user-friendly graphical interfaces can be built. For example, the more complex the structure of a rule is, the more difficult it is to interpret, and hence, the less interesting it is likely to be. This query is input to the system. • There are several proposals on data mining languages and standards. Rules whose support and confidence values are below user-specified thresholds are considered uninteresting. knowledge presentation and visualization techniques to be used for displaying the discovered patterns . Data Evaluation and Presentation – Analyzing and presenting results Description: Design graphical user interfaces based on a data mining query language ... CIKM'94, Gaithersburg, Maryland, Nov. 1994. Data can be associated with classes or concepts. List and describe data mining task primitives. • This facilitates a data mining system’s communication with other information systems and its integration with the overall information processing environment. • Data Mining Primitives: A data mining task can be specified in the form of a data mining query which is input to the data mining system Classification in Data Mining - Tutorial to learn Classification in Data Mining in simple, easy and step by step way with syntax, examples and notes. Rather than mining on the entire database. R. Data Mining Task Primitives 10. The data mining tasks can be classified generally into two types based on what a specific task tries to achieve. These primitives allow the user to inter- actively communicate with the data mining system during discovery in order to direct the mining process, or examine the findings from different angles or depths. Suppose currently you want to mine the data for Germany. • These primitives allow the user to interactively communicate with the data mining system during discovery in order to direct the mining process, or examine the findings from different angles or depths. An example of a concept hierarchy for the attribute (or dimension) age is shown in Figure 1.2. We can classify a data mining system according to the kind of databases mined. Best Data Mining Objective type Questions and Answers. Data Mining Task Primitives Each user will have a data mining task in mind, that is, some form of data analysis that he or she would like to have performed. The expected representation for visualizing the discovered patterns: This refers to the form in which discovered patterns are to be displayed, which may include rules, tables, charts, graphs, decision trees, and cubes. Data measuring airborne pollutants, public health and environmental factors are increasingly being stored and merged.
