Lesson 22 Joining NumPy Arrays Using Stack Functions in Machine Learning

In this video I will show you how to use stack function in Python NumPy. Stacking is same as concatenation, the only difference is that stacking is done along a new axis. We can concatenate two 1-D arrays along the second axis which would result in putting them one over the other, ie. stacking. We pass a sequence of arrays that we want to join to the stack() method along with the axis. If axis is not explicitly passed it is taken as 0.
