+# Unrestricted Adversarial Challenge
+
+This is a submission for the unrestricted adversarial challenge: Phase I. The
+entry is uses a pretrained ImageNet model with Local Linearity Regularizer, then
+adversarially trained using birds-or-bicycles dataset (train and extras) as
+provided by the challenge.
