Number of coeffecients in Temperature Prediction Project


I am very much impressed by the content of the course. However, I would be happy if you guys can clear my doubt i.e. How to indentify what shall be the number of coeffecients used in Temperature Prediction Project ?

If is there any trick, then please help us to know so that time and energy can be saved in tuning the model with minimum error coeffecients in predicting polynomial regression.

Looking forward for the fast and accurate reply/

Apologies for the late reply. My colleague @vinayak.joshi will answer your query by EOD.
