Polynomial regressionI'm curious about using polynomial regression with multiple features. I understand how to use polynomial hypotheses with univariate regression, but I'm unsure how to extend this to multiple features. Let's say I want to use a cubic polynomial. Do I introduce three terms in the hypothesis for each feature x^1 and x^2 and x^3 ?? So in effect, I'm tripling the number of features (or terms in the hypothesis equation)?
Thank you. Daniel |

Re: Polynomial regressionDear Dr. Magdon,
Thank you so much for the informative reply. Of course, your solution makes perfect sense. It just wasn't obvious to me. I shall experiment with this. Cheers, Daniel |
