Configuration & Hyperparameters
All of the configuration settings are stored in a config.py file in the relevant code directory. All hyperparameters can be changed from the default value in the hyperparams.py file for a particular experiment.
This page contains all of the config settings that are exposed via the experiment hyperparams file. See the corresponding config files for more detailed comments on each variable.
