Lab 1 - Collaborative Filtering

Hello @Sudhir_Nandamuru,

You need to make sure the formula is implemented correctly. Note that the regularization term is outside of the error term (pay attention to the square brackets that I have used to separate the two).


Therefore, you have loops for the error terms only, and after you complete calculating the error terms, you add the regularization term.


PS: Next time, please just open a new thread for your own question, instead of writing replies in multiple threads.
