Packages that use RandomEngine | |
---|---|
org.apache.mahout.math.jet.random | Large variety of probability distributions featuring high performance generation of random numbers, CDF's and PDF's. |
org.apache.mahout.math.jet.random.engine | Engines generating strong uniformly distributed pseudo-random numbers; Needed by all JET probability distributions since they rely on uniform random numbers to generate random numbers from their own distribution. |
