Settings
Here we can find the main settings that are needed for controling the code. Below, the settings are grouped as tables, you can find the counterpart code file here. However, there are another parameters that need to be specified through the commandline, as they are considered the most important paramters in our experiments, you can find a description of them here
Default Settings
Parameter |
Value |
Description |
Epsilon |
0.1 |
A parameter that prevents the BIV function from having high loss values. |
Threshold |
