Air Polution Regression Problem
isn’t working , are you facing any problem /error ? can you please be more brief.
What is wrong with my code?
My analogy >
Training data seems like linear so I’m trying to put best line on every feature to obtain theta so that every next time I can predict y for any value of x(feature)
…
I writed this code to To get theta i wrote this code and i am getting the same(theta) But when I process theta with the given features in the training data, the output it gives me is different from the given target value.
…
hey buddy,
thats absolutely correct , you won’t get the same value.
Linear regression tries to lower the difference , it will always be a a non-zero value of loss. So , as close as possible you can reach , its more good.
