Overview: The research explores the utilization of Extreme Value Theory (EVT) to predict the worst-case convergence times of machine learning algorithms. Such predictions are crucial for ensuring the availability and reliability of ML services, but current methods struggle to provide accurate information due to inherent uncertainty and noise.

Key Insights:

• EVT models improve accuracy in predicting convergence times compared to traditional statistical methods such as Bayesian analysis.
• The EVT approach is practical for both simple linear ML training algorithms and more complex deep learning neural network applications.
• It offers insights into the likelihood and expected return periods of worst-case scenarios.

Opinions: The paper makes a significant contribution by addressing the challenge of predicting ML performance under extreme conditions. Using EVT could lead to more reliable and robust AI systems, essential for critical applications like autonomous driving or healthcare diagnostics.
