### Question:
XaiverRandomizeNetwork extends AbstractRandomizeNetwork { @Override public void randomize(BasicNetwork network) { for (int i = 0; i < network.getLayers().size() - 1; i++) { randomizeLayer(network, i); } }  @Override void randomize(BasicNetwork network);  }### Answer:
@Test public void testRandomize() { BasicNetwork network = new BasicNetwork(); network.addLayer(new BasicLayer(null,true,2)); network.addLayer(new BasicLayer(new ActivationSigmoid(),true,3)); network.addLayer(new BasicLayer(new ActivationSigmoid(),false,1)); network.finalizeStructure(); XaiverRandomizeNetwork randomize = new XaiverRandomizeNetwork(); randomize.setRnd(new LinearCongruentialRandom(10)); randomize.randomize(network); double[] expected = {-0.48063016461488856, -0.6268874420756946, 3.2098992119169534E-4, -0.1914041699971798, 1.040596563646283, -0.485186340462527, -1.110171460956511, -1.0430309621862426, -0.13325874823843634, -0.18257850835630843, 0.228311697697274, 0.2916967306617774, -0.43452699284274987}; Assert.assertArrayEquals(expected,network.getWeights(), AIFH.DEFAULT_PRECISION); }
