How do you save progress during a Keras Tuner run?
I am currently shifting through a larger search space with Keras Tuner on a free Google Colab instance. Because of usage limits, my search run will be interrupted before completion. I would like to save the progress of my search periodically in…

Keras BayesianOptimization tuner makes the "best val_loss" worse during tuning
I'm tuning a model with the Keras tuner BayesianOptimization. The tuning objective is val_loss which is calculated after each epoch. As I understand it, the tuner will go through various hyperparameter configurations and train the model while…

How to use "LeakyRelu" and Parametric Leaky Relu "PReLU" in Keras Tuner
I am using Keras Tuner and using RandomSearch() to hypertune my regression model. While I can hypertune using "relu" and "selu", I am unable to do the same for Leaky Relu. I understand that the reason "relu" and "selu" string works because, for…

Keras Tuner: Accessing the data in the directory created during Hyperparameter Tuning using the Keras Tuner in Google Colab
I am tuning an ANN model using the Keras Tuner, using the Bayesian optimizer as follows:
tuner = BayesianOptimization (
build_model,
objective=kt.Objective('val_auc', direction='max'),
max_trials=30,
executions_per_trial=10,

Keras Tuner return validation losses from hyperparameter search
Using Keras-tuner to create a hyperparameter tuning object and calling the search method, it is easy to retrieve the best hyperparameter configurations once the search is complete, however there does not appear to be any in-built way to also return…

Keras Hyperband Search Using Directory Iterator
I am using Tensorflow's flow_from_directory to collect a large image dataset and then train on it. I want to use Keras Tuner but when I run
tuner.search(test_data_gen, epochs=50,
validation_split=0.2, callbacks=[stop_early])
It…

Keras Tuner Save Best Model
I am currently attempting to used keras tuner to create a model for my CNN, though I am having some issues with saving my model for future use.
As I am used to it, I could regularly just save my model with model.save(filename) to receive a .model…

How can I load a keras-tuner project by name?
I ran multiple projects using keras-tuner and named them. Now I can't figure out how to load the projects to check the best results of each one since the tuner is just the last run and I wanted to check the results with models =…

Naming of Keras Tuner Trials directory for TensorBoard
I am using Keras tuner's BayesianOptimization to search for the optimum hyper parameters of a model, I am also using the TensorBoard callback with it to visualise the performance of each model/trial.
However, the trials from the Tuner are…

How to get equivalent behavior of Keras tuner RandomSearch when using Dask
I have an existing hyperparameter search in Keras using kerastuner.tuners.RandomSearch. It looks like this:
tuner = RandomSearch(build_model,
objective='val_loss',
max_trials=18,
executions_per_trial=3,
)
I look at dask documentation…

Google Colab keeps crashing when trying to run keras tuner
This is my first machine learning project, working with a dataset i have created on my own.
Unfortunately Google Colab keeps crashing.
And it seems to have something to do with keras tuner, but i am not sure.
It actually worked for a while.
But now…
