Question 6
Marks : +2 | -2
Pass Ratio : 100%
What is the objective of pattern recall?
it should not take place when relations are disturbed
it should take place when relations are slightly disturbed
there is no such objective of recall, it depends on the system
none of the mentioned
Explanation:
The pattern recall should take place even though features and their spatial relations are slightly disturbed due to noise.
