a$)$ that the model's learnable parameter W$1$ has an initial weight of $0\mathrm{.}7$ and learning rate$=0\mathrm{.}1.$ Consider the table given and determine the change in weight $($Delta$)$ for all three epochs by applying Momentum to Gradient Descent optimization. Also, while estimating momentum, assume the beta value is $0\mathrm{.}9.[5$ marks$]$

b$)$ Assume that the model's learning rate "alpha" has been initialized as $0\mathrm{.}5.$ Consider the table given and compute the change in learning rate using AdaGrad optimization. $[5$ marks$]$
