### MODULE 3 – ARTIFICIAL NEURAL NETWORKS

1. What is Artificial Neural Network?

2. Explain appropriate problem for Neural Network Learning with its characteristics.

3. Explain the concept of a Perceptron with a neat diagram.

4. Explain the single perceptron with its learning algorithm.

5. How a single perceptron can be used to represent the Boolean functions such as AND, OR

6. Design a two-input perceptron that implements the boolean function A Λ ¬ B. Design a two-layer network of perceptron that implements A XOR B.

7. Consider two perceptrons defined by the threshold expression w0 + wlxl+ w2x2 > 0.
