1. Add the arbiter Maven dependency in pom.xml:

<dependency>
   <groupId>org.deeplearning4j</groupId>
   <artifactId>arbiter-deeplearning4j</artifactId>
   <version>1.0.0-beta3</version>
 </dependency>
 <dependency>
   <groupId>org.deeplearning4j</groupId>
   <artifactId>arbiter-ui_2.11</artifactId>
   <version>1.0.0-beta3</version>
 </dependency>

2. Configure the search space using ContinuousParameterSpace:

ParameterSpace<Double> learningRateParam = new ContinuousParameterSpace(0.0001,0.01);

3. Configure the search space using IntegerParameterSpace:

ParameterSpace<Integer> layerSizeParam = new IntegerParameterSpace(5,11);   

4. Use OptimizationConfiguration to combine all components required to execute the hyperparameter tuning process:

OptimizationConfiguration optimizationConfiguration = new             OptimizationConfiguration.Builder()
 .candidateGenerator(candidateGenerator)
 .dataProvider(dataProvider)
 .modelSaver(modelSaver)
 .scoreFunction(scoreFunction)
 .terminationConditions(conditions)
 .build();
