Question for the instructor
PloynomialFeature() function in Scikit-learn library, generates a new feature matrix consisting of all polynomial combinations of the features with degree less than or equal to the specified degree.

Question for the instructor
My "ML0101EN-Reg-Polynomial-Regression-Co2-py-v1" exercise equation is:
yy = clf3.intercept[0]+ clf3.coef[0][1]XX+ clf3.coef_[0][2]np.power(XX, 2)+ clf3.coef_[0][3]*np.power(XX, 3)The instructor's is:
yy = clf3.intercept[0]+ clf3.coef[0][1]XX + clf3.coef_[0][2]np.power(XX, 2) + clf3.coef_[0][2]*np.power(XX, 3)Note especially "clf3.coef_[0][2]*np.power(XX, 3)" is this correct?

Not always so clear on when I have a correct answer
Your user interface doesn't always make it clear that I am correct. Also adding print(xxxxx) to the answer when you're asking for output shouldn't be counted as wrong.

I suggest you require prerequisites before allowing anybody to enroll in this program
Taking the data science classes by anybody unfamiliar with any of the basic programs used during this course makes no sense. It's monumentally frustrating trying to figure out the basics like this:
Exercise 3: (Jupyter notebook)
2. From the menu, click on "Insert", then "Insert Cell Above" or "Insert Cell Below".; While it's clear how to insure one or the cells, it's difficult to figure out how to enter the second now.
3. Note you can use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Really? What am I suppose to click on??????1 vote -
