AdaStop: Cost-Aware Early Stopping for DNN Test Selection
Summary
AdaStop is a novel framework designed for cost-aware early stopping in deep neural network (DNN) testing, addressing the challenge of optimizing labeling budgets. Traditional DNN testing methods focus on identifying faults under a predetermined budget, often leading to either insufficient testing or excessive labeling costs. AdaStop reframes DNN testing as a cost-benefit decision process, where labeling an input incurs a cost $c$ and discovering a fault yields a value $v$. The framework operates by continuously estimating the marginal fault discovery rate during testing and halts the labeling process when this rate drops below a predefined threshold, $τ= c/v$. Experimental results demonstrate AdaStop's efficiency, enabling the discovery of 65-84% of faults while utilizing only 9-31% of the total labeling budget across diverse datasets, network architectures, and test selection strategies.
Key takeaway
For Machine Learning Engineers managing DNN testing and labeling budgets, AdaStop offers a critical shift from fixed budgets to dynamic, cost-aware stopping. You should consider integrating a framework like AdaStop to optimize resource allocation, potentially discovering 65-84% of faults with only 9-31% of traditional labeling costs. This approach ensures more efficient quality assurance by halting testing precisely when marginal fault discovery no longer justifies the labeling expense.
Key insights
AdaStop optimizes DNN testing costs by dynamically stopping labeling when the marginal fault discovery rate falls below a cost-benefit threshold $τ= c/v$.
Principles
- DNN testing is a cost-benefit decision.
- Dynamic stopping optimizes labeling budgets.
- Marginal fault discovery rate is a stopping signal.
Method
AdaStop estimates the marginal fault discovery rate during DNN testing. It stops labeling when this rate falls below the threshold $τ= c/v$, balancing labeling cost $c$ against fault discovery value $v$.
In practice
- Reduce DNN test labeling costs.
- Improve fault discovery efficiency.
- Implement $τ= c/v$ as a stopping criterion.
