DATA MINING Multiple Choice Questions :- 1. some value as input and produces some value as output all the instances of that concept Advertisements. To get a decent relationship with the customer, a business organization needs to collect data and analyze the data. Data Definition Language C. Relational Model Association rule finds interesting association or correlation relationships among a large set of data items which is used for decision-making processes. The training data is shown below. To integrate heterogeneous databases, how many approaches are there in Data Warehousing? Classification of data mining frameworks according to data mining techniques used: This classification is as per the data analysis approach utilized, such as neural networks, machine learning, genetic algorithms, visualization, statistics, data warehouse-oriented or database-oriented, etc. To integrate heterogeneous databases, we have the following two approaches : Query Driven Approach, Update Driven Approach. 21. Classification is the data analysis method that can be used to extract models describing important data classes or to predict future data trends and patterns. Data Mining Multiple Choice Questions and Answers. In the data mining domain where millions of records and a large number of attributes are involved, the execution time of existing algorithms can become prohibitive, particularly in interactive applications. Suppose that a search engine retrieves 10 documents after a user enters ‘data mining’ as a query, of which 5 are data mining related documents. Binary attribute are | Data Mining Mcqs . This takes only two values. I think we all have a brief idea about data mining but we need to understand which types of data can be mined. In data mining, a classification is a form of data analysis where a machine learning model assigns a certain category or class to new observations. Explanation: there are two categories of functions involved in Data Mining : 1. 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 means Data Mining System Classification consists of?
