AI Training's Hidden Fractal Chaos
Fractal patterns explain why AI training diverges despite identical conditions.

š„ What happened
University of Sydney researchers proved neural networks diverge even with identical data and deterministic hardware. The culprit is a fractal structure in the training landscape they call "riddled basins." They trained roughly 500,000 networks to confirm the pattern.
š” Why it matters
Making starting conditions 10 billion times more precise yielded zero measurable gain in reproducibility. A single bit of difference flipped the outcome in 48% of cases. Anyone betting on more numerical precision to fix this is in for a shock.
ā” Our take
Reproducibility isn't a bug to patch ā it's baked into the math of these networks. Building medical or legal AI on the promise of deterministic behavior means building on sand.
