Q:

Emphasizing a noun using hyphening to create adjective

I am trying to emphasize the notion of (accumulation process) as an adjective using hyphening. I tried using accumulative-like but I am not sure if it does make sense! 
My sentence is:

This is accomplished by an accumulative-like training process by partitioning the large dataset into smaller subsets each fits the
  memory.

I appreciate in advance any suggestion or modification

A:

Accumulative is an adjective in itself. It expresses the quality or type of something that results in an accumulation. 
So it should be enough to say: 

"This is accomplished by an accumulative training process by
  partitioning the large dataset into smaller subsets that each fits the
  memory."
