Once I first started studying Data analytics course in Pune and machine studying, I began (as so much do) by attempting to foretell stocks.

However, this case is extra more likely to happen when the number of samples is small and the variety of class is excessive. On this situation, the stratification course of could also be crucial. I am wondering if folks normally apply stratification or not and why. Feel free to touch upon this difficulty relating to your personal expertise.
