Data Mining & Data Ware House
51. KDD (Knowledge Discovery in Database) is referred to
  • Non-trivial extrction of implicit previusly unknown and potentially useful information from dat (A)
  • Set of columns in a database table that can be used to identify each record within this table uniquely.
  • collection of interesting and useful patterns in a database
  • None of these
Show Answer
52. Key is referred to
  • Non-trival extrction of implicit previously unknown and potentially useful information from dat(A)
  • Set of columns in a database table that can be used to identify each record within this tabel uniquely
  • Collection of interesting and useful patterns in database
  • None of these
Show Answer
53. Inductive learning is
  • Machine-learning involving different techniques
  • The learning algorithmic analyzes the examples on a systematic basis and makes incremental adjustments to the theory that is learned
  • Learning by generalizing from examples
  • None of these
Show Answer
54. Integrated is
  • The amount of information with in data as opposed to the amount of redundancy or noise
  • One of the defining aspects of a data warehouse
  • Restriction that requires data in one column of a database table to the sub-set of another-column
  • None of these
Show Answer
55. Knowledge engineering is
  • The process of finding the right formal representation of a certain body of knowledge in order to represent it in a knowledge-based system
  • It automatically maps an external signal space into a system's internal representational space. They are useful in the performance of classification tasks
  • A process where an individual learns how to carry out a certain task when situation in which the task cannot be carried out to a situation in which the same task under the same circumstances can be carried out.
  • None of these
Show Answer
56. Kohonen self-organizing map referred to
  • The process of finding the right formal representation of a certain body of knowledge in order to represent it in a knowledge-based system
  • It automatically maps an external signal space into a system's internal representational space. they are useful in the performance of classification tasks
  • A process where an individual learns how a carry out a certain task when making a transition from a situation in which the task cannot be carried out to a situation in which the same task under the same circumstaces can be carried out.
  • None of these
Show Answer
57. Learning is
  • The process of finding the right formal representation of a certain body of knowledge in order to represent it in a knowledge-based system
  • It automatically maps an external signal space into a system's internal representational space. they are useful in the performance of classification tasks.
  • A process where an individual learns how to carry out a certain task when making a transition from a situation in a situation in which the same task under the same circumstances can be carried out.
  • None of these
Show Answer
58. Learning algorithm referrers to
  • An algorithm that can learn
  • A sub-discipline of computer science that deals with the design and imp-lementation of learning algorithms.
  • A machine-learning approach that abstracts from the actual strategy of an individual algorithm and can therefore be applied to any other form of machine learning.
  • None of these
Show Answer
59. Meta-learning is
  • An algorithm that can learn
  • A sub-discipline of computerscience that deals with the design and implementation of learning algorithms.
  • A machine-learning approach that abstracts from the actual strategy of an invdividual algorithm and can therefore be applied to any other form of machine learning.
  • None of these
Show Answer
60. Meta-learning is
