Verification is formulated as a classification problem with two classes - faces and nonfaces. For classification we used SNoW (Sparse Network of Winnows) classifier. For gathering nonface templates we used bootstrap method.

In Appendix 10, we will develop the theory of ‘winnowability’ of p-concept classes for its own sake.
A Full Characterization of Quantum Advice
In the second stage, our goal is just to winnow S ′ down to a particular function f .
A Full Characterization of Quantum Advice
Definition 32 (Winnowability) S is winnowable if for al l nonempty subsets S ′ ⊆ S, there exists a certificate C of size poly (n) such that |S ′ [C ]| = 1.
A Full Characterization of Quantum Advice
Then |S | ≤ 2poly(n) iff VCdim (S ) ≤ poly (n) iff S is learnable iff S is approximable iff S is majority-isolatable iff S is winnowable.
A Full Characterization of Quantum Advice
For |S | ≤ 2poly(n) =⇒Winnowable, let S ′ ⊆ S .
A Full Characterization of Quantum Advice
Then as in the proof of Lemma 3, we can use binary search to winnow S ′ down to a single function f ∈ S ′, which yields a certificate of size at most log2 |S ′ | ≤ log2 |S |.
A Full Characterization of Quantum Advice
For Winnowable=⇒ |S | ≤ 2poly(n), we prove the contrapositive.
A Full Characterization of Quantum Advice

Definition 34 (Winnowability) A p-concept class S is L1 -winnowable if the fol lowing holds.
A Full Characterization of Quantum Advice
Likewise, S is L2 -winnowable if ∆2 (f, g) [X ] ≤ δ implies ∆∞ (f, g) ≤ ε, and L∞ -winnowable if ∆∞ (f, g) [X ] ≤ δ implies ∆∞ (f, g) ≤ ε.
