Answer #1

PLEASE GIVE IT A THUMBS UP, PLEASE I SERIOUSLY NEED ONE

4.1. In Spark we've many forms of vectors to represent the string in

Given, (8, [1,4,5], [0.871, 1.0, 0.447])

In this It has a size of 8, [1,4,5] represent the indices, the rest represent the values which are non-zero

It means that the vector has

0.871 at 1st position

1.0 at 4th position

0.447 at 5th position

------------------------------------------------------------------

4.2. It's helpful in computation and storage management. Such a string is used to provide clear reference.
