Hi all

I have made a network using the deep learning toolbox with various hyperparameters such as mini-batch size and number of neurons per layer etc. Currently I am using a grid search to find the best combinations but is there a way to use the genetic algortihm in the Optimization toolbox to find the best architecture? I have read similar threads but none seem to explain how one could achieve this. Any explanations or examples of code would be really appreciated!

Hello Raidoo,

Will you like to share your Grid search or GA code for deep learning time series data ? If can not any other help ?

Thanks
