Learning cost-sensitive active classifiers

R Greiner, AJ Grove, D Roth - Artificial Intelligence, 2002 - Elsevier
Most classification algorithms are “passive”, in that they assign a class label to each instance
based only on the description given, even if that description is incomplete. By contrast, an …

On PAC learning algorithms for rich boolean function classes

L Hellerstein, RA Servedio - Theoretical Computer Science, 2007 - Elsevier
We give an overview of the fastest known algorithms for learning various expressive classes
of Boolean functions in the Probably Approximately Correct (PAC) learning model. In …

PAC learning with irrelevant attributes

A Dhagat, L Hellerstein - Proceedings 35th Annual Symposium …, 1994 - ieeexplore.ieee.org
We consider the problem of learning in the presence of irrelevant attributes in Valiant's PAC
model (1984). In the PAC model, the goal of the learner is to produce an approximately …

[图书][B] Matters Horn and other features in the computational learning theory landscape: the notion of membership

MD Frazier - 1994 - search.proquest.com
Current knowledge representation research has sought to provide schemes for encoding
knowledge about how a given system behaves, with the goal being accuracy and utility …

On learning counting functions with queries

Z Chen, S Homer - Proceedings of the seventh annual conference on …, 1994 - dl.acm.org
We investigate the problem of learning disjunctions of counting functions, generalizations of
parity and modulo functions, with equivalence and membership queries. We prove that, for …

Combinatorial results on the complexity of teaching and learning

T Hegedüs - Mathematical Foundations of Computer Science 1994 …, 1994 - Springer
Some recent work in computational learning theory has focused on the complexity of
teaching by examples. In this paper we study two combinatorial measures expressing the …

An algebraic perspective on boolean function learning

R Gavaldà, D Thérien - International Conference on Algorithmic Learning …, 2009 - Springer
In order to systematize existing results, we propose to analyze the learnability of boolean
functions computed by an algebraically defined model, programs over monoids. The …

On learning disjunctions of zero-one threshold functions with queries

T Hegedüs, P Indyk - International Workshop on Algorithmic Learning …, 1997 - Springer
We investigate the learnability of the class κ-ZOTF n of disjunctions of (at most) κk zero-one
threshold functions with queries. We describe a poly (n)-time algorithm that identifies any …

[PDF][PDF] On the learnability of Zn-DNF formulas

NH Bshouty, Z Chen, SE Decatur… - Proceedings of the eighth …, 1995 - dl.acm.org
Although many learning problems can be reduced to learning Boolean functions, in many
cases a more efficient learning algorithm can be derived when the problem is considered …

On approximating weighted sums with exponentially many terms

D Chawla, L Li, S Scott - Journal of Computer and System Sciences, 2004 - Elsevier
Multiplicative weight-update algorithms such as Winnow and Weighted Majority have been
studied extensively due to their on-line mistake bounds' logarithmic dependence on N, the …
