Deep learning Previous Year Questions

Module 1: Fundamentals of Neural Network

---

2024 Paper:

1. Q1 a) Design AND gate using Perceptron.
2. Q1 b) Suppose we have N input-output pairs. Our goal is to find the parameters that predict the output (y) from the input (x) according to some function (y = xw). Calculate the sum-of squared error function (E) between predictions (y) and inputs (x). The parameter (w) can be determined iteratively using gradient descent. For the calculated error function (E), derive the gradient descent update rule (w \leftarrow w – \alpha).
