A1=(1 two 3) B1=(4 three 2)
A2=(2 three 4) B2=(3 five 2)
A3=(3 four 6) B3=(2 two 1)
Determining whether Ai= M - Bi

4. explain in detail the 2 additive bivalent neural Network models and compare them.

5. a. What is competitive learning? How does it differ from signal Hebbrian learning.
b. elaborate Fuzzy Cognitive Maps? How can they be used to combined opinion of multiple experts?

6. a. explain the essential differences ranging from supervised and unsupervised learning in Neural Nets.
b. explain different learning algorithms and write their limitations.

7. a. State the fuzzy entropy Theorem and discuss it suitable example.
b. Write the entropy - subsethood theorem and its implications

8. a. What is Fuzzy centroid defuzzification scheme? discuss how is it used in FAM system architecture.
b. Use Correlation - Minimum encoding to construct the FAM matrix M from the fit- Vector pair (A,B) if A=(0.6, 1, 0.2, 0.9) and B=(0.8, 0.3, 1.0). Is (A.B) a bi-directional fined points? Pass A”=(0.2, 0.9, 0.3, 0.2) through M and B”=(0.9, 0.5, 1.0) though MT. Do the recalled fuzzy sets differ from B and A?
