A data scientist is using a code segment to refine hyperparameters for a machine learning model with the following parameters: num_evals = 5, trials = SparkTrials(), and inside the objective function, they use 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.
