Trojan VQA
Written by Matthew Walmer
Tools to manage the model collections for the TrojVQA dataset. Modes:
--pack: take models and results from their sub-module locations to model_sets/v1/
--unpack: take models from the model_sets/v1/ and copy them to the sub-modules to be run
--move: move files instead of copying them (copy is default behavior)
--export: after all models are packed, export a train and test set for defense research
--subver: choose which sub-version to export (see below)
Details of datasets composed:
v1-(train/test)-dataset (base)
-480 models total
-240 clean models
-120 dual-key trojans with solid visual triggers
-120 dual-key trojans with optimized visual triggers
-320 train / 160 test
v1a-(train/test)-dataset (a)
-240 models total
-120 clean models
-120 dual-key trojans with solid visual triggers
-160 train / 80 test
v1b-(train/test)-dataset (b)
-240 models total
-120 clean models
-120 dual-key trojans with optimized visual triggers
-160 train / 80 test
v1c-(train/test)-dataset (d)

-120 single key trojans with only solid visual triggers
-160 train / 80 test
v1d-(train/test)-dataset (d)

-120 clean models
-120 single key trojans with only optimized visual triggers
