and you want to search over only a few parameters (such as the learning rate), you can do so by passing a <code>hyperparameters</code> argument to the tuner constructor, as well as <code>tune_new_entries=FALSE</code> to specify that parameters that you didn’t list in <code>hyperparameters</code> should not be tuned. For these parameters, the default value gets used.</p>
