I've committed detailed results of this detector's performance on the test set to this PR.

Warning

Failed to find threshold values that achieve False Positive Rate(s): (['1%']) on all domains. This submission will not appear in the main leaderboard for those FPR values; it will only be visible within the splits in which the target FPR was achieved.
On the RAID dataset as a whole (aggregated across all generation models, domains, decoding strategies, repetition penalties, and adversarial attacks), it achieved an AUROC of 77.97 and a TPR of 58.03% at FPR=5%.
Without adversarial attacks, it achieved AUROC of 93.54 and a TPR of 80.96% at FPR=5%.

If all looks well, a maintainer will come by soon to merge this PR and your entry/entries will appear on the leaderboard. If you need to make any changes, feel free to push new commits to this PR. Thanks for submitting to RAID!
