Note: i) Question paper consists of Part A, Part B. ii) Part A is compulsory, which carries 25 marks. In Part A, Answer all questions. iii) In Part B, Answer any one question from each unit. Each question carries 10 marks and may have a, b as sub questions.
PART A
Compare neural network with human brain.
Answer
The human brain is a highly complex, parallel, and fault-tolerant biological system with approximately 10 to the power of 11 neurons. In contrast, an artificial neural network is a simplified mathematical model that mimics the brain's structure using interconnected processing units (neurons) to perform parallel distributed processing for specific computational tasks.
What is error correction learning? Explain.
Answer
Error correction learning is a supervised learning process where the weights of a neural network are adjusted based on the difference between the actual output and the desired target output. The network iteratively minimizes this error signal, typically using a gradient descent approach, to improve the accuracy of its predictions over time.
