Section AAttempt all questions in brief. 2 x 10 = 20
  • a
    What are the key differences between soft computing and hard computing?
  • b
    Define an artificial neuron and describe its basic structure
  • c
    What is the role of activation function in a neural network?
  • d
    Explain the concept of fu zzification and its purpose
  • e
    List different types of learning in neural networks
  • f
    What are the key operation s in a genetic algorithm?
  • g
    Define membership function in fuzzy logic
  • h
    What is crossover in genetic algorithms and why is it importan t? 4 K5 i. Explain the term ‘swarm intelligence’. 5 K3 j. What are hybrid soft computi ng techniques? Give an example
Section BAttempt any three of the following: 10 x 3 = 30
  • a
    Critically evaluate how the choice of activation function a ffects the learning capability, convergence, and performance of a neural n etwork in real-world applications suc h as image recognition or languag e processing. Justify your reasoning with suitable examples
  • b
    Explain the architecture and training process of multilayer perceptron
  • c
    Various Fuzzy set operations e xtend classical set theory to handle uncertainty and vagueness. Critical ly analyze how these operati ons enable better modeling of real-wo rld problems compared to crisp logic. Choose a real-life scenario (e.g., air conditioner control, risk assessment, or medical diagnosis) and demonstrate how fuzzy set operations enhance decision-making in that context
  • d
    Explain the structure and wo rking of a Kohonen Self-Organizing Map
  • e
    Explain the concepts of Genetic Algorithm. Analyze and evalu ate how each step of a GA—selection, c rossover, and mutation—contribute s to finding optimal or near-optimal s olutions. Also, discuss potent ial challenges in applying GAs effectively
Section CAttempt any one part of the following: 10 x 1 = 10
  • a
    Explain supervised, unsupervised, and reinforcement learning w i t h suitable examples
  • b
    Critically analyze how soft co mputing differs from hard comp uting in dealing with real-world comple xity. Choose a practical applicat ion domain (such as medical diagnosis, autonomous vehicles, or fina ncial prediction) and argue why soft c omputing is better suited than traditional hard computing approaches
  • a
    Compare and contrast Perceptr on and Backpropagation networks. Also, Design a perceptron that impleme nts the logical AND function. P rovide the weight updates for each training step using a learning rate of 1
  • b
    Explain the architecture and features of a Hopfield Network. 2 K 4
  • a
    Explain fuzzy inference system with a diagram. Describe its components. Also, Given fuzzy set A = {(1, 0.3), (2, 0.5), (3, 0.7), (4, 1)}, compute the α-cut for α = 0.6 and the complement of A
  • b
    Differentiate between Mamdani and Sugeno inference systems
  • a
    Explain the process of encoding, crossover, and mutation in GA with examples. Also, Apply single-point crossover and mutation on: Parent 1: 11010101 Parent 2: 10101011 Crossover after 4th bit; fli p 3rd bit of offspring
  • b
    Compare and contrast Genetic A lgorithms (GAs), Genetic Programming (GP), and Evolutionary Strategie s (ES) in the context of solvin g real- world optimization problems. Choos e one real-world problem (e.g ., route optimization, financial forecasting, robotic control, etc.) and justify which of the three would be the most appropriate approach and why
  • a
    Describe the neuro-fuzzy hybrid system with a suitable application
  • b
    Swarm Intelligence algorithms such as Particle Swarm Optimiz ation (PSO) and Ant Colony Optimization (ACO) are inspired by collect ive behavior in nature. Critically e valuate how these algorithms mi mic real- world swarm behavior to solve optimization problems. Choose a specific application (e.g., network routi ng, task scheduling, or vehicle routing) and analyze the advantages and limitations of using swarm intel ligence for that problem
