Question 1

Enrichment is
A)a stage of the kdd process in which new data is added to the existing selection
B)the process of finding a solution for a problem simply by enumerating all possible solutions according to some pre-defined order and then testing them
C)the distance between two points as calculated using the pythagoras theorem.
D)none of these

Accepted Answer

Enrichment in the context of the Knowledge Discovery in Databases (KDD) process refers to the stage where new data is added to the existing dataset to enhance its value, quality, or usefulness for further analysis or processing.

Question 2

Heterogeneous databases referred to
A)a set of databases from different b vendors, possibly using different database paradigms
B)an approach to a problem that is not guaranteed to work but performs well in most cases.
C)information that is hidden in a database and that cannot be recovered by a simple sql query.
D)none of these

Accepted Answer

Heterogeneous databases are those that involve a set of databases from different vendors, which may use different database paradigms (such as relational, NoSQL, etc.), making integration and querying across these databases more complex.

Question 3

Enumeration is referred to
A)a stage of the kdd process in which new data is added to the existing selection.
B)the process of finding a solution for a problem simply by enumerating all possible solutions according to some pre-defined order and then testing them
C)the distance between two points as calculated using the pythagoras theorem.
D)none of these

Accepted Answer

Enumeration refers to the process of finding a solution by listing all possible solutions in a systematic order and then evaluating them to find the correct one. This method is exhaustive and ensures that no potential solution is overlooked.

Question 4

Heuristic is
A)a set of databases from different vendors, possibly using different database paradigms
B)an approach to a problem that is not guaranteed to work but performs well in most cases
C)information that is hidden in a database and that cannot be recovered by a simple sql query.
D)none of these

Accepted Answer

Heuristic refers to a problem-solving approach that employs a practical method or various shortcuts to produce solutions that may not be optimal but are sufficient for reaching an immediate goal. It is often used when an exhaustive search is impractical. Choices A and C describe different concepts unrelated to heuristics, and D is incorrect because B accurately defines a heuristic.

Question 5

Hybrid learning is
A)machine-learning involving different techniques
B)the learning algorithmic analyzes the examples on a systematic basis 2nd makes incremental adjustments to the theory that is learned
C)learning by generalizing from examples
D)none of these

Accepted Answer

Hybrid learning in the context of machine learning refers to approaches that involve combining different techniques or algorithms to improve learning outcomes or to tackle problems that are difficult to solve using a single method.
