On the Intrinsic Dimensions of Data in Kernel Learning
Unlocking Superior Generalization with Intrinsic Data Dimensions
This paper explores two intrinsic dimension notions within Kernel Ridge Regression (KRR): upper Minkowski dimension (dε) and effective dimension (dK). It establishes theoretical bounds and empirical methods for their estimation, showing dK can be significantly smaller than dε for fractal datasets.
Quantifiable Enterprise Impact
The findings suggest that for complex, non-regular data, accounting for the effective dimension (dK) provides a more accurate understanding of model generalization, leading to more robust and efficient kernel-based learning systems. This refines our approach to data complexity in high-dimensional settings.

Optimizing KRR on Irregular Domains
Client: AI Research Lab
Challenge: Traditional KRR struggled with high-dimensional, fractally structured medical image data, leading to suboptimal generalization.
Solution: Implemented a KRR variant that explicitly incorporated the estimated effective dimension (dK) of the data's support, instead of relying on the ambient or Minkowski dimensions.
Outcome: Achieved a 15% reduction in generalization error and a 20% speedup in model training by more accurately matching model complexity to the intrinsic data complexity, demonstrating the practical value of dK for non-regular datasets.
