Accelerating Adversarial Training on Under-Utilized GPU
Bibliographic record
Abstract
Deep neural networks are vulnerable to adversarial attacks and adversarial training has been proposed to defend against such attacks by adaptively generating attacks, i.e., adversarial examples, during training. However, adversarial training is significantly slower than traditional training due to the search for worst attacks for each minibatch. To speed up adversarial training, existing work has considered a subset of a minibatch for generating attacks and reduced the steps in the search for attacks. We propose a novel adversarial training acceleration method, called AttackRider, by exploring under-utilized GPU hardware to reduce the number of calls to attack generation without increasing the time of each call. We characterize the extent of under-utilization of GPU for given GPU and model size, hence the potential for speedup, and present the application scenarios where this opportunity exists. The results on various machine learning tasks and datasets show that AttackRider can speed up state-of-the-art adversarial training algorithms with comparable robust accuracy. The source code of AttackRider is available at https://github.com/zxzhan/AttackRider.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
