Hyper-parameters can be loosely defined as parameters that do not change during training. For example, the number of layers in an FFNN, the number of neurons in each layer, activation functions, learning rate, and so on. This chapter deals with how to tune hyper-parameters in the most efficient way.Michelucci, Umberto

因此,以往大模型的训练可以说都是不完整的,缺少了“超参数调优”这一重要环节,然而,最近微软和OpenAI合作的新工作μTransfer为大模型的超参数调优提供了解决方案,如图1所示,即先在小模型上进行超参数调优,再迁移到大模型,下面将对该工作进行简单介绍,详细内容可参考论文《Tensor Programs V: Tuning Large Neural ...

💡This blog post is part 1 in our series on hyperparameter tuning. If you're looking for a hands-on look at different tuning methods, be sure to check out part 2,How to tune hyperparameters on XGBoost, and part 3,How to distribute hyperparameter tuning using Ray Tune. ...
The first step in hyperparameter tuning is to decide whether to use a manual or automated approach. Manual tuning means experimenting with different hyperparameter configurations by hand. This approach provides the greatest control over hyperparameters, maximizing the ability to tailor se...
