+## Performance:
+Although the concrete performance improvements depends on the sparsity of the dataset. The algorithms
 in SparseSpark generally significantly reduce the time and memory consumption compared with the original
 Spark implementation.

-The optimization does not affect the accuracy. It yields the same result with the original Spark version,
-yet with much less resources.
