Efficient Hyperparameter Optimization in Deep Learning Using a Variable Length Genetic Algorithm

1 code implementation23 Jun 2020 Xueli Xiao, Ming Yan, Sunitha Basodi, Chunyan Ji, Yi Pan

However, traditional genetic algorithms with fixed-length chromosomes may not be a good fit for optimizing deep learning hyperparameters, because deep learning models have variable number of hyperparameters depending on the model depth.
