What is the correct way to define conditional hyperparameters in Keras Tuner
I want to create autoencoder and optimize its hyperparameters using Keras Tuner. I want it to contain from 1 to 3 layers in encoder part and each layer to contain less neurons than the previous layer (but more than latent dimensionality, which is…

Keras Tuner hyperband epoch
I am running Keras Tuner(Hyperband) since Random search does not find optimal solution, I would like to know how we can control the number of models and epochs to run. In Randomsearch we can clearly give it in max trials and execution per trial but…

Keras Tuner get_best_hyperparameters()
Is there any way to have the best hyperparameters get returned as a list that I can access in other parts of my code?
I don't want the entire model, I just want to be able to extract the values of the optimal hyperparameters it finds and use it in a…

Is it possible to view multiple tuner runs at once on tensorboard hparams tab?
I'm using Keras tuner to do hyperparameter optimization on a particular hypermodel which is then trained for different cases (i.e. different houses). My goal for now is to get an easy, straightforward visualisation of what generally works, and what…

got nan in keras tuner but it works when I train it
I trained my network several times and I already got some results. Then I found out about the Keras tuner and wanted to find the best hyperparameters with it. but the loss in tuner always becomes nan ( it won't get nan if you train it regularly).…

Dependent hyperparameters with keras tuner
My goal is to tune over possible network architectures that meet the following criteria:
Layer 1 can have any number of hidden units from this list: [32, 64, 128, 256, 512]
Then, the number of hidden units to be explored for the rest of the layers…
