Extract Valid Grid from Compilation Results

This helper function filters the results from compile_keras_grid() to return a new hyperparameter grid containing only the combinations that compiled successfully.

Usage

extract_valid_grid(compiled_grid)

Arguments

compiled_grid

A tibble, the result of a call to compile_keras_grid().

Value

A tibble containing the subset of the original grid that resulted in a successful model compilation. The compiled_model and error columns are removed, leaving a clean grid ready for tuning.

Details

Filter a Grid to Only Valid Hyperparameter Sets

After running compile_keras_grid(), you can use this function to remove problematic hyperparameter combinations before proceeding to the full tune::tune_grid().

Examples

if (FALSE) { # \dontrun{
# Continuing the example from `compile_keras_grid`:

# `compiled_grid` contains one row with an error.
valid_grid <- extract_valid_grid(compiled_grid)

# `valid_grid` now only contains the rows that compiled successfully.
print(valid_grid)

# This clean grid can now be passed to tune::tune_grid().
} # }
