A data scientist employs the a code segment to refine hyperparameters for a machine learning model: num evals = 5, trials = SparkTrials(), to get the best hyperparam. And for that, inside the objective function, they use the following parameters: space-search space, algo-tpe.suggest, max_evals=num_evals, trials = trials. Which modification can they apply to the aforementioned code to increase the chances of obtaining a more precise model? Choose only ONE best answer.
