We describe a new incremental algorithm for training linear threshold functions: the Relaxed Online Maximum Margin Algorithm, or ROMMA. ROMMA can be viewed as an approximation to the algorithm that… (More)

A broad class of boosting algorithms can be interpreted as performing coordinate-wise gradient descent to minimize some potential function of the margins of a data set. This class includes AdaBoost,… (More)

We investigate the PAC learnability of classes of {0,…,n}-valued functions. For n = 1, it is known that the finiteness of the Vapnik-Chervonenkis dimension is necessary and sufficient for learning.… (More)

1 I n t r o d u c t i o n Many important applied problems can be modeled as learning from random examples. Examples include text categorization [22], handwrit ten character recognition [16, 4, 8],… (More)

We address the computational complexity of learning in the agnostic framework. For a variety of common concept classes we prove that, unless P=NP, there is no polynomial time approximation scheme for… (More)

We describe a polynomial-time algorithm for learning axis-aligned rectangles in Q d with respect to product distributions from multiple-instance examples in the PAC model. Here, each example consists… (More)

We consider the problem of learning real-valued functions from random examples when the function values are corrupted with noise. With mild conditions on independent observation noise, we provide… (More)
