Data Mining Set 1

It is hidden within a database and can only be recovered if one is given certain clues (an example IS encrypted information). ✘ The process of executing implicit previously unknown and potentially useful information from data ✘ An extremely complex molecule that occurs in human chromosomes and that carries genetic information in the form of genes. ✘ None of these ✔

A stage of the KDD process in which new data is added to the existing selection. ✘ 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 ✘ The distance between two points as calculated using the Pythagoras theorem ✘ None of these ✔

A set of databases from different vendors, possibly using different database paradigms ✘ An approach to a problem that is not guaranteed to work but performs well in most cases ✘ Information that is hidden in a database and that cannot be recovered by a simple SQL query. ✘ None of these ✔

Machine-learning involving different techniques ✘ The learning algorithmic analyzes the examples on a systematic basis 2nd makes incremental adjustments to the theory that is learned ✘ Learning by generalizing from examples ✘ None of these ✔

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 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 ✔
