data mining & data ware house set 2 Detailed Explanation And More Example

Question : 1

Knowledge is referred to

a) Non-trivial extraction of implicit previously unknown and potentially useful information from dat(A)

b) Set of columns in a database table that can be used to identify each record within this table uniquely.

c) collection of interesting and useful patterns in a database

d) none of these

Question : 2

Back propagation networks is

a) Additional acquaintance used by a learning algorithm to facilitate the learning process

b) A neural network that makes use of a hidden layer

c) It is a form of automatic learning.

d) None of these

Question : 3

Integrated is

a) The amount of information with in data as opposed to the amount of redundancy or noise

b) One of the defining aspects of a data warehouse

c) Restriction that requires data in one column of a database table to the a subset of another-column.

d) None of these

Question : 4

Kohonen self-organizing map referred to

a) The process of finding the right formal representation of a certain body of knowledge in order to represent it in a knowledge-based system

b) It automatically maps an external signal space into a system’s internal representational space. They are useful in the performance of classification tasks

c) A process where an individual learns how to 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 circumstances can be carried out.

d) None of these

Question : 5

a) It uses machine-learning techniques. Here program can learn from past experience and adapt themselves to new situations

b) Computational procedure that takes some value as input and produces some value as output.

c) Science of making machines performs tasks that would require intelligence when performed by humans

d) None of these
