Scale-Sensitive Shattering: Learnability and Evaluability at Optimal Scale

Han Shao, Shashaank Aiyer, Shay Moran, Tom Waknine, Yishay Mansour

For any bounded real-valued function class, uniform convergence at scale γ is equivalent to agnostic learnability at scale γ/2 and finite fat-shattering dimension at all scales above γ.

Claims

C1strongest claim

for every bounded real-valued class and every γ>0, uniform convergence at scale γ, agnostic learnability at scale γ/2, and finiteness of the fat-shattering dimension at every scale γ'>γ are equivalent

C2weakest assumption

The real-valued function class must be bounded, which is required for the scale-sensitive notions of uniform convergence and learnability to be well-defined.

C3one line summary

For bounded real-valued function classes, uniform convergence at scale γ, agnostic learnability at γ/2, and finite fat-shattering dimension above γ are equivalent.
