$($ii$)$ Consider the dataset given below having two input

variables $x1,x2$ and one output variable $y.$ Update the

coefficients ${}_0,{}_1$ and ${}_2$ using gradient descent for

the logistic regression model. Assume the learning

rate $=0\mathrm{.}3$ and the initial values of coefficients as

${}_0=-0\mathrm{.}5,{}_1=1,$ and ${}_2=-1.$ Perform one iteration

of gradient descent.
