Описание

Bayesian optimization helps pinpoint the best configuration for your machine
learning models with speed and accuracy. Put its advanced techniques into
practice with this hands-on guide.

Bayesian Optimization in Action

you will learn how to:

Train Gaussian processes on both sparse and large data sets

Combine Gaussian processes with deep neural networks to make them flexible and
expressive

Find the most successful strategies for hyperparameter tuning

Navigate a search space and identify high-performing regions

Apply Bayesian optimization to cost-constrained, multi-objective, and
preference optimization

Implement Bayesian optimization with PyTorch, GPyTorch, and BoTorch

Bayesian Optimization in Action

shows you how to optimize hyperparameter tuning, A/B testing, and other
aspects of the machine learning process by applying cutting-edge Bayesian
techniques. Using clear language, illustrations, and concrete examples, this
book proves that Bayesian optimization doesn’t have to be difficult! You’ll
get in-depth insights into how Bayesian optimization works and learn how to
implement it with cutting-edge Python libraries. The book’s easy-to-reuse code
samples let you hit the ground running by plugging them straight into your own
projects.

About the technology

In machine learning, optimization is about achieving the best
predictions—shortest delivery routes, perfect price points, most accurate
recommendations—in the fewest number of steps. Bayesian optimization uses the
mathematics of probability to fine-tune ML functions, algorithms, and
hyperparameters efficiently when traditional methods are too slow or
expensive.

About the book

Bayesian Optimization in Action

teaches you how to create efficient machine learning processes using a
Bayesian approach. In it, you’ll explore practical techniques for training
large datasets, hyperparameter tuning, and navigating complex search spaces.
This interesting book includes engaging illustrations and fun examples like
perfecting coffee sweetness, predicting weather, and even debunking psychic
claims. You’ll learn how to navigate multi-objective scenarios, account for
decision costs, and tackle pairwise comparisons.
