Hello EveryoneI want to switch my career in Data Science and have been learning Machine Learning since last two weeks. I want to learn optimization technique and applying the BFGS algorithm on some data to get optimize value of theta in linear regression.When I'm running my code in python, it gives the following error:> derphi0 = np.dot(gfk, pk)> ValueError: shapes (3,47) and (3,47) not aligned: 47 (dim 1) != 3 (dim0)Any help will be appreciated.Following is my python code for the…See More

Hello everyone,I want to minimize J(theta) of Logistic regression by using Gradient Descent(GD) algorithm.I have wrote a code in matlab and python both by using GD but getting the value of theta very less/different(wrt fminunc function of Matlab) For example: for the given set of data, by using GD algorithm, with following input:num_iters=400; alpha=0.0001;got the following output:theta:= [-0.002717 ; 0.010242; 0.000669]For a student with scores 45 and 85, we predict an admission probability of…See More
