GPyOpt is a Python open-source library for Bayesian Optimization developed by the Machine Learning group of the University of Sheffield. It is based on GPy, a Python framework for Gaussian process modelling. With GPyOpt you can: Automatically configure your models and Machine Learning algorithms. I want to try and compare different optimization methods in some datasets. I know that in scikit-learn there are some corresponding functions for the grid and random search optimizations. However, I also need a package (or multiple ones) for different recent Bayesian optimization methods.

A Bayesian Network captures the joint probabilities of the events represented by the model. A Bayesian belief network describes the joint probability distribution for a set of variables. — Page 185, Machine Learning, 1997. Central to the Bayesian network is the notion of conditional independence. 2019-08-01T05:06:45Z tag:joss.theoj.org,2005:Paper/1142 2019-08-01T05:06:45Z 2020-03-14T00:51:54Z

This is the first post in a series about distilling BERT with multimetric Bayesian optimization. Part 2 discusses the set up for the Bayesian experiment, and Part 3 discusses the results. You’ve all heard of BERT: Ernie’s partner in crime. Just kidding! I mean the natural language processing (NLP) architecture developed by Google in 2018.

In many real-world scenarios, decision makers seek to efficiently optimize multiple competing objectives in a sample-efficient fashion. Multi-objective Bayesian optimization (BO) is a common approach, but many of the best-performing acquisition functions do not have known analytic gradients and suffer from high computational overhead... Variational inference (VI) instead approximates posteriors through optimization. Recent theoretical and computational advances in automatic variational inference have made VI more accessible. This talk will give an introduction to VI and show software packages for performing VI in Python.
