Q$\mathrm{.}2-$a$)[$Marks: $5=2+3]$ What is the loss function of the perceptron algorithm $?$ Please justify.

Q$\mathrm{.}2-$b$)[$Marks: $5]$ You are given a perceptron with d$-$dimensional input, $x=(x^1,x^2,$dots,$x^d)$ where each

element of the input, i$.$e$.,x^i$ is either $0$ or $1.$ Find the weights such that perceptron returns $1$ if majority

of the elements are $1$ or else the perceptron returns $0.$
