data mining task primitives

Find answer to specific questions by searching them here. Data Extraction – Occurrence of exact data mining 3. • A data mining task can be specified in the form of a data mining query, which is input to the data mining system. • The language adopts an SQL-like syntax, so that it can easily be integrated with the relational query language, SQL. Data-Warehouses (DW) 4. A data mining query is defined in terms of data mining task primitives. • A data mining query is defined in terms of data mining task primitives. 8.2 Data mining primitives: what defines a data mining task? interestingness measures .  The set of task-relevant data to be mined  The kind of knowledge to be mined  The background knowledge  Interestingness measures and thresholds for pattern evaluation  The expected representation for visualizing the discovered patterns 5. This represents the portion of the database that needs to be investigated for getting the results. task-relevant data. In a data mining task where it is not clear what type of patterns could be interesting, the data mining system should Select one: a. allow interaction with the user to guide the mining process b. perform both descriptive and predictive tasks c. perform all possible data mining tasks d. handle different granularities of data and patterns Show Answer Data Mining Primitives, Languages, and System Architectures. R. In this book, we use a data mining query language known as DMQL (Data Mining Query Language), which was designed as a teaching tool, based on the above primitives. For example, suppose that you are a manager of All Electronics in charge of sales in the United States and Canada. Those two categories are descriptive tasks and predictive tasks. A data-mining task can be specified in the form of a data-mining query, which is input to the data mining system. Data Mining Primitives Explained In Detail. Classification of Data Mining Systems 9. Task-Relevant Data. These primitives allow the user to interactively communicate with the data mining system during discovery in order to direct. • Having a data mining query language provides a foundation on which user-friendly graphical interfaces can be built. The background knowledge to be used in the discovery process: This knowledge about the domain to be mined is useful for guiding the knowledge discovery process and for evaluating the patterns found. background knowledge. The descriptive data mining tasks characterize the general properties of data whereas predictive data mining tasks perform inference on the available data set to predict how a new data set will behave. To this end, data mining and machine learning … Data Mining Task Primitives 10. Types Of Data Used In Cluster Analysis - Data Mining, Data Generalization In Data Mining - Summarization Based Characterization, Attribute Oriented Induction In Data Mining - Data Characterization. Data Mining Functionalities 8. Database system can be classified according to different criteria such as data models, types of data, etc. • 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. mining primitives specify the following: List the five primitives for specification of a data mining task. Task Relevant Data Kinds of knowledge to be mined Background knowledge Interestingness measure Presentation and visualization of discovered patterns If there was no user intervention then the system would uncover a large set of patterns and insights that may even surpass the size of the database. Task-relevant data: This is the database portion to be investigated. Most of the times, it can also be the case that the data is not present in any of these golden sources but only in the form of text files, plain files or sequence files or spreadsheets and then the data needs to be processed in a very similar way as the processing would be done upon … Objective measures of pattern simplicity can be viewed as functions of the pattern structure, defined in terms of the pattern size in bits, or the number of attributes or operators appearing in the pattern. Data Mining Task Primitives. The kind of knowledge to be mined: This specifies the data mining functions to be per- formed, such as characterization, discrimination, association or correlation analysis, classification, prediction, clustering, outlier analysis, or evolution analysis. 1.7 Data Mining Task Primitives 31 1.8 Integration of a Data Mining System with a Database or Data Warehouse System 34 1.9 Major Issues in Data Mining 36 vii.
