District Data Labs - Parameter Tuning with Hyperopt

This post will cover a few things needed to quickly implement a fast, principled method for machine learning model parameter tuning. There are two common methods of parameter tuning: grid search and random search. Each have their pros and cons. Grid search is slow but effective at searching the whole search space, while random search is fast, but could miss important points in the search space. Luckily, a third option exists: Bayesian optimization.
