Grid search hyperparameters.

Hyperparameter	param-1	param-2	param-3	param-4	param-5	param-6
learning-rate	0.1	0.01	0.001	–	–	–
layers & nodes	[32, 32]	[32, 64]	[32, 64, 128]	[32, 64, 128, 256]	[32, 64, 128, 256, 512]	–
dropout	0.0	0.1	0.2	0.3	0.4	0.5

The bold values represent the tuned hyperparameters resulted from the grid search approach.

The symbol “–” means that the corresponding value or field is empty or has no data.
