Soft Computing - May 2014

Computer Engineering (Semester 7)

TOTAL MARKS: 100
TOTAL TIME: 3 HOURS
(1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks.
1(a) Explain fuzzy extension principle with the help of an example.(6 marks) 1(b) Model the following as a fuzzy set using suitable membership function - 'numbers close to 10'.(6 marks) 1(c) Explain standard fuzzy membership functions.(8 marks) 2 Design a fuzzy controller to determine the wash time to domestic washing machine. Assume that the inputs are dirt and grease on clothes. Use three descriptors for each input variable and five descriptors for the output variable. Device a set of rules for control action and defuzzification. The design should be suported by figures wherever possible. Clearly indicate that if the clothes are solid to a larger the wash time required will be more.(20 marks) 3(a) What is learning? Compare different learning rules.(10 marks) 3(b) Explain error back propagation training algorithm with the help of a flowchart.(10 marks) 4(a) Implement the perceptron rule training using f(net) = sgn(net), c=1, and the following data specifying the initial weights W1, and the two training pairs,
W1 = [0, 1, 0]t
X1 = [2, 1, -1]t d1 = -1;
X2 = [0, 1, -1]t d2 = 1;
Repeat the training sequence until two correct responses in a row are achieved.
(10 marks)
4(b) Explain Hebbain Learning with the help of an example.(10 marks) 5(a) Explain with examples linearly separable and non-linearly separable pattern classification.(10 marks) 5(b) Explain the architecture of ANFIS with the help of a diagram.(10 marks) 6(a) Explain with an example Genetic Algorithm.(10 marks) 6(b) Explain RBF network and give the comparison between RBF and MLP.(10 marks)


Write a short note on any two

7(a) Derivative based Optimization(10 marks) 7(b) Learning vector quantization(10 marks) 7(c) Character recognition using neural network.(10 marks) 7(d) Kohonen's self organizing network.(10 marks)
