Back 1

Artificial intelligence

Front 2

What Al method is used for the following processes?

A) Separate data into subsets and then analyse the subsets to divide them into further subsets for a number of levels.

B) continually analyse and compare data until patterns emerge.

C) Divide data into groups baed on similar features or limited data ranges.

Back 2

a) decision trees

b) neural networks

c) clustering

Front 3

what term is used for the ptarrens found by neural networks?

Back 3

rules

Front 4

when are clusters used in data mining?

Back 4

when data isnt't labelled in a way that is favourable to mining

Front 5

what types of data storage can be used in data minig?

Back 5

all types of data storage, from arge data warehouses to smaller desktop databases to flat files.

Front 6

What cant an analyst do to improve the data mining results

Back 6

a)refine the parameters

b) use other data analysis tools to examine the data

Back 17

large amount of data stored in data warehouses are often used for data mining. the data is first cleansed to remove duplicate data and errors. The data is then analysed using a tool such as artifiacl intelligen. An analysing report is then analysed by an analyst who decides if the parameters need to be refined, other data analysis tools need to be uesd or if the results need to be discarded because the are unsusable. the analyst passes the final result to the decision makers who decide on the appropriate action.
