Abstract
Bots have become popular in software projects as they play critical roles, from running tests to fixing bugs/vulnerabilities. However, the large number of software bots adds extra effort to practitioners and researchers to distinguish human accounts from bot accounts to avoid bias in data-driven studies. Researchers developed several approaches to identify bots at specific activity levels (issue/pull request or commit), considering a single repository and disregarding features that showed to be effective in other domains. To address this gap, we propose using a machine learning-based approach to identify the bot accounts regardless of their activity level. We selected and extracted 19 features related to the account's profile information, activities, and comment similarity. Then, we evaluated the performance of five machine learning classifiers using a dataset that has more than 5,000 GitHub accounts. Our results show that the Random Forest classifier performs the best, with an F1-score of 92.4% and AUC of 98.7%. Furthermore, the account profile information (e.g., account login) contains the most relevant features to identify the account type. Finally, we compare the performance of our Random Forest classifier to the state-of-the-art approaches, and our results show that our model outperforms the state-of-the-art techniques in identifying the account type regardless of their activity level.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
