The Boolean Hierarchy and the Polynomial Hierarchy: a Closer Connection
We show that if the Boolean hierarchy collapses to level k, then the polynomial hierarchy collapses to BH3(k), where BH3(k) is the kth level of the Boolean hierarchy over P 2 . Th...

The Complexity of Learning Concept Classes with Polynomial General Dimension
The general dimension is a combinatorial measure that characterizes the number of queries needed to learn a concept class. We use this notion to show that any p-evaluatable concep...

Graduated Errors in Approximate Queries Using Hierarchies and Ordered Sets
Abstract. Often, qualitative values have an ordering, such as (veryshort, short, medium-height, tall) or a hierarchical level, such as (TheWorld, Europe, Spain, Madrid), which are ...

On the Structure of Bounded Queries to Arbitrary NP Sets
Kadin [6] showed that if the Polynomial Hierarchy (PH) has infinitely many levels, then for all k, PSAT[k] ⊂ PSAT[k+1]. This paper extends Kadin’s technique and shows that a p...
