Asked about Tuning, in order of what matters
Why does random search beat grid search?
An answer that works
Most hyperparameters barely matter. A grid spends its budget evenly, so it tries only a few distinct values of the one that does. Random search tries a different value of every parameter on every run, exploring the important dimension far more thoroughly for the same compute.
