Shattering the Illusion: The Real Deal on Certified Training in Neural Nets

Deep neural networks have transformed supervised learning, achieving impressive feats across various tasks. Yet, their Achilles' heel remains adversarial perturbations. Neural network verification offers strong guarantees against these, but at the expense of significant computational resources. Certified training seeks to bridge this gap, but at what cost to accuracy?

Behind the Certified Curtain

Certified training methods claim to optimize the balance between natural and certified accuracy. However, these metrics often find themselves at odds. Industry practice of touting single configuration results doesn't help, often painting a skewed picture of true performance. If methods are inherently conflicting, why are we sticking to a one-size-fits-all approach?

Pareto front comparisons present a more nuanced view. By evaluating the trade-offs between natural and certified accuracy, we can unearth the real value of certified training methods. This isn't just about numbers. It's about redefining the state of the art through rigorous, unbiased evaluations.

Unveiling the Optimization Myth

The use of automated multi-objective hyperparameter optimization reveals a startling truth: many prior configurations were sadly undertuned. When we dive deep with this method-agnostic approach, we find that superior performance isn't just possible. it's waiting to be discovered. Are researchers missing the forest for the trees by clinging to outdated configurations?

This comprehensive multi-objective comparison shatters previously held assumptions. It turns out, those dazzling advancements weren't as groundbreaking as touted. Instead, we find previously unreported performance complementarities, showcasing that the real gains lie in the details, not the headlines.

The Real State of the Art

Here's the kicker: certified training methods need more than just a facelift. They require a fundamental re-evaluation of how performance is measured and reported. The intersection is real. Ninety percent of the projects aren't. By focusing on Pareto-optimal configurations, we not only enhance results but also elevate the entire field.

So, the next time you read about a breakthrough in certified training, ask yourself: How thoroughly was it tuned? Because in the race for robustness, slapping a model on a GPU rental isn't a convergence thesis. It's time to show the inference costs. Then we'll talk about the true state of the art.
