Neural Networks question bank on “Pattern Association – 2”.
1. What are hard problems?
A. classification problems which are not clearly separable
A. classification problems which are not associatively separable
A. classification problems which are not functionally separable
D. none of the mentioned
Answer: D
Clarification: Classification problems which are not linearly separable separable are known as hard problems.
2. In order to overcome constraint of linearly separablity concept of multilayer feedforward net is proposed?
A. yes
B. no
Answer: A
Clarification: Multilayer feedforward net with non linear processing units in intermidiate hidden layer is proposed.
3. The hard learning problem is ultimately solved by hoff’s algorithm?
A. yes
B. no
Answer: B
Clarification: The hard learning problem is ultimately solved by backpropagation algorithm.
4. What is generalization?
A. ability to store a pattern
B. ability to recall a pattern
C. ability to learn a mapping function
D. none of the mentioned
Answer: C
Clarification: Generalization is the ability to learn a mapping function.
5. Generalization feature of a multilayer feedforward network depends on factors?
A. architectural details
B. learning rate parameter
C. training samples
D. all of the mentioned
Answer: A
Clarification: Generalization feature of a multilayer feedforward network depends on all of these above mentioned factors.
6. What is accretive behaviour?
A. not a type of pattern clustering task
B. for small noise variations pattern lying closet to the desired pattern is recalled.
C. for small noise variations noisy pattern having parameter adjusted according to noise variation is recalled
D. none of the mentioned
Answer: B
Clarification: In accretive behaviour, pattern lying closet to the desired pattern is recalled.
7. What is Interpolative behaviour?
A. not a type of pattern clustering task
B. for small noise variations pattern lying closet to the desired pattern is recalled.
C. for small noise variations noisy pattern having parameter adjusted according to noise variation is recalled
D. none of the mentioned
Answer: C
Clarification: In interpolative behaviour, pattern having parameter adjusted according to noise variation is recalled & not the ideal one.
8. Does pattern association involves non linear units in feedforward neural network?
A. yes
B. no
Answer: B
Clarification: There are only two layers & single set of weights in pattern association.
