I want to try implementing Multivariate Locally weighted regression on this problem. I wrote this code https://ide.codingblocks.com/s/118200 but when I try the output for the first row of test case it gives an error that dimensions of theta and x do not match.
Since in video, the multivariate case was not explained. How do I go about correcting this?

Hello @S18LPC-OL0076,
I have updated the code here. Now it seems working, although I havent properly went through your implementation, I have corrected the error that you reported.
Happy Learning 
Thanks

Hello @Manu-Pillai-1566551720093198,
Yes thanks it is cleared.
On a side note, could you direct/refer me to some material detailing on Multivariate Locally Weighted Regression ? The tutorials only cover the case of one feature. I was facing issues implementing the algorithms when multiple features are involved.
Hello @S18LPC-OL0076,
Implementing Multivariate Locally Weighted Regression is same as implementing multivariate linear regression. You can easily find an implementation on the internet. Medium is a good place to start looking for one.
Thanks
