Question 7; calculating slope in PythonHi I was trying to implement this in Python. To get the target function which is a line of form y = mx+c, I started by calculating the slope (m). If line passes through the points (x1,y1) and (x2,y2) then m = (y2-y1)/(x2-x1). But as you know these points are randomly picked and in some cases I get (x2-x1) = 0; which generates divide by zero exception.
My question is How did you deal with this problem?? |

Re: Question 7; calculating slope in PythonHow are you generating your random points? If you use numpy to generate the coordinates of one point, it shouldn't happen. Try this:
Code:
`x, y = np.random.uniform(-1,1,2)` |
