Traditionally, hyper-parameter optimization has been the job of humans because they can be very efficient in regimes where only a few trials are possible. Presently, computer clusters and GPU processors make it pos- sible to run more trials and we show that algorithmic approaches can find better...
The impact of these hyperparameters on algorithm performance should not be underestimated (Kim et al.2017; Kong et al.2017; Singh et al.2020; Cooney et al.2020); yet, their optimization (hereafter referred to ashyperparameter optimizationor HPO) is a challenging task, as traditional optimizatio...
This guide shows you how to create a new hyperparameter optimization (HPO) tuning job for one or more algorithms. To create an HPO job, define the settings for the tuning job, and create training job definitions for each algorithm being tuned. Next, configure the resources for and create th...

常用的正则化方法有L1正则化和L2正则化。L2正则化因为计算比较高效,使用更为广泛。但L1正则化可以使模型简单并提高可解释性。L1和L2正则化的利弊如图所示: 数据增强也是常用的正则化手段,它通过创建假样本并加入到训练集中从而避免过拟合。这在CV领域的图片分类和物体检测上比较常见。

To run a hyperparameter optimization (HPO) training job, first create a training job definition for each algorithm that's being tuned. Next, define the tuning job settings and configure the resources for the tuning job. Finally, run the tuning job. ...
Efficient Hyperparameter Optimization of Deep Learning Algorithms Using Deterministic RBF Surrogates - ili3p/HORD
Now we can use the nature-inspired algorithms for hyper-parameter tuning.We are using theBat Algorithmfor optimization. We will train the population size of 25 individuals and will stop the algorithm if the algorithm won’t find a better solution in 10 generations. We will do this...
