Create a gradient descent algorithm for one cost function with local minima and $1$ cost function with only global minima $($for $2$ cost functions$),$ and show learning rate effect $.$Select $2$ any datas.$($ with python codes pls$.)$Create a new gradient descent algorithm with $1$ cost function with local minima and $1$ cost function with global minima.We need a single code and we should be able to display the graphs when we run the code.
