TPE gets its name from two main ideas: 1. using Parzen Estimation to model our beliefs about the best hyperparameters (more on this later) and 2. using a tree-like data structure called a posterior-inference graph to optimize the algorithm runtime. In this example we will ignore the “tr...
Hyperparameter optimization (HPO) is crucial for strong performance of deep learning algorithms. A widely-used versatile HPO method is a variant of Bayesian optimization called tree-structured Parzen estimator (TPE), which splits data into good and bad groups and uses the density ratio of those ...
TPE全称Tree-structured Parzen Estimator,是用GMM(Gaussian Mixture Model)来学习超参模型的一种方法。 首先把 Bayes 引入进来,p(x|y) 即模型 loss 为 y 的时候超参为 x 的条件概率。第一步,我们根据已有的数据选取一个 loss 的阈值 y*,比如按照中位数。对大于阈值和小于阈值的数据,分别学习两个概率密度 ...

Tree-structured parzen estimator (TPE) is a method based on the Bayesian approach to tune the hyperparameters of models. The Gaussian process-based approach directly simulates 𝑝(𝑦|𝜃)p(y|θ), and the TPE strategy simulates 𝑝(𝜃|𝑦)p(θ|y) and 𝑝(𝑦)p(y) to indirectly...
