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

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 99.58 and a TPR of 98.48% at FPR=5% and 95.48% at FPR=1%.
Without adversarial attacks, it achieved AUROC of 99.78 and a TPR of 99.24% at FPR=5% and 97.46% at FPR=1%.

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!
