Please explain the sparse vector in Spark.

Question Posted / sameer jha


Please explain the sparse vector in Spark...

Answer / Abhijeet Verma

A sparse vector is a mathematical object used to represent vectors with many zero elements. In Spark, a sparse vector is represented by SparseVector. It's efficient because it doesn't store non-zero values explicitly for all indices, instead, it stores the index and value pairs for non-zero entries.
