Examples with NativeRandom org.nd4j.rng.NativeRandom used on opensource projects

Example 1 with NativeRandom

use of org.nd4j.rng.NativeRandom in project nd4j by deeplearning4j.

the class RandomTests method testStepOver3.

@Test
public void testStepOver3() throws Exception {
    Random random = Nd4j.getRandomFactory().getNewRandomInstance(119);
    if (random instanceof NativeRandom) {
        NativeRandom rng = (NativeRandom) random;
        assertTrue(rng.getBufferSize() > 1000000L);
        int someInt = rng.nextInt();
        for (int e = 0; e < 10000; e++) rng.nextInt();
        random.setSeed(119);
        int sameInt = rng.nextInt();
        assertEquals(someInt, sameInt);
        random.setSeed(120);
        int otherInt = rng.nextInt();
        assertNotEquals(someInt, otherInt);
    } else
        log.warn("Not a NativeRandom object received, skipping test");
}

Example 2 with NativeRandom
