....for experimental machine learning research. Angluin and Laird provided an algorithm for learning boolean conjunctions that tolerates a noise rate approaching the information theoretic barrier of 1=2. Subsequently, there have been some isolated instances of efficient noisetolerant algorithms [14, 20, 22], but little work on characterizing which classes can be efficiently learned in the presence of noise, and no general transformations of Valiant model algorithms into noise tolerant algorithms. The primary contribution of the present paper is in making significant progress in both of these areas. ....
....1 Gamma ffi satisfies error(h) ffl. This probability is taken over the random draws from D made by EX (f; D) and any internal randomization of L. We call ffl the accuracy parameter and ffi the confidence parameter. 3 The Classification Noise Model The well studied classification noise model [1, 15, 11, 24, 14, 20, 22] is an extension of the Valiant model intended to capture the simplest type of white noise in the labels seen by the learner. We introduce a parameter 0 j 1=2 called the noise rate, and replace the oracle EX (f; D) with the faulty oracle EX j CN (f; D) where the subscript is the acronym for ....

....polynomial in 1= 1 Gamma 2j) in addition to the usual other parameters. This specifically answers an open question proposed by Rivest [24] concerning the learnability of decision lists in such a noisy setting. This problem of learning noisy decision lists was solved independently by Sakakibara [25]. Theorem 3.2 Let 2 [0; 1] be fixed, and let F n be a basis of functions. Then the p concept class of probabilistic decision lists over basis F n with converging probabilities is learnable with a model of probability (assuming both and F n are known) Specifically, this class can be ....
