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 estimatorSHAPThe optimum fragmentation size measures the quality of a blasting operation. Boulders or large fragments can result in more costs because they need secondary blasting, while small fragments can result in ore loss and dilution. Therefore, it is very significant to ...
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 ...

Firstly, the hyperparameters of the proposed model are automatically tuned by a Bayesian optimization algorithm, called Tree-structured Parzen Estimator (TPE). Secondly, the proposed model allows assessing the uncertainty on the prediction. To validate the performance of the proposed model, a case ...
