(SEM III) THEORY EXAMINATION 2022-23 INTRODUCTION TO SOFT COMPUTING

This question paper belongs to the subject Soft Computing, designed for undergraduate engineering students. The paper carries a total of 100 marks and is divided into three sections: A, B, and C. Students must attempt all sections, and any missing data may be assumed suitably.

The paper evaluates a student's conceptual understanding, analytical ability, and problem-solving skills in the domains of Neural Networks, Fuzzy Logic, Genetic Algorithms, and Hybrid Soft Computing Models.

Section A (20 Marks – Short Answer Questions)

This section contains 10 brief questions, each carrying 2 marks.
Questions test fundamental knowledge of:

Learning rate

Soft computing concepts

Basics of genetics (cell & chromosomes)

Fuzzy vs crisp logic

Fuzzy Cartesian product

Disjunctive sum of fuzzy sets

Bias function in neural networks

Complexity

Activation functions

Membership functions

This section checks the student’s basic theoretical foundation.

Section B (30 Marks – Descriptive Questions)

Students must attempt any 3 out of 5 questions, each worth 10 marks.
This section requires detailed explanations of:

Realization of AND using perceptron

Characteristics & applications of neural networks

Multi-layer perceptron & soft computing applications

Neuro-fuzzy systems

Fuzzy automata

These questions examine the student’s ability to explain concepts with clarity and depth.

Section C (50 Marks – Long Answer / Numerical / Analytical Problems)

This section contains five sub-sections, and the student must attempt one part from each, making it the most scoring section.

It includes:

Numerical problems (e.g., KSOM clustering, back-propagation iteration)

Conceptual explanations (e.g., fuzzy control, hybrid systems)

Detailed algorithms (e.g., genetic algorithm phases)

System models (e.g., ANFIS with Mamdani model)
