Topic: Winnow


  
  Winnow
This property seems crucial in domains in which the feature space is vast, but a relatively small number of features is relevant (this does not mean that only those will be active, or have non-zero weights).
Winnow is known to learn any linear threshold function efficiently, to be robust in the presence of various kinds of noise and in cases where no linear threshold function can make perfect classification, and to still maintain its above-mentioned dependence on the number of total and relevant attributes [
We note that the original Winnow algorithm is a positive weight algorithm.

 SpamFilter - PineWiki
Note that unlike Bayesian filters, this learning algorithm is not affected by how many times it sees the same message, and ignores any message that it correctly classifies (so you can run it on your entire inbox twice a day, but it probably won't improve its classifications unless it has been making mistakes).

To simplify the data 14 kept around, weights are always adjusted by 1/2 or 2 and Blum's enhancement 15 of Winnow that reduces the weight of a specialist whenever it votes wrong 16 (even if the majority votes right) is not used.

 Text Chunking using Regularized Winnow - Zhang, Damerau, Johnson (ResearchIndex)
Among them, the Winnow algorithm has been argued to be particularly suitable for NLP problems, due to its robustness to irrelevant features.
To remedy this problem, a modification called regularized Winnow has been proposed.
The basic idea is to modify the original Winnow algorithm so that it solves a regularized optimization problem.

 SNoW
The SNoW (Sparse Network of Winnows) learning architecture is a multi-class classifier that is specifically tailored for large scale learning tasks and fpr domains in which the potential number of features taking part in decisions is very large, but may be unknown a priori.
In this way, when using Winnow, it is a feature efficient learning algorithm, in that it scales linearlly with the number of relevant features, and linearly with the number of features active in the domain.
However, there are a few differences worth mentioning relative to simply using the basic update rule, which we briefly describe here in the context of the Winnow update rule, the most successful one in most applications.

 IBM Research - Trainable Information Extraction Systems
This architecture is based on the Winnow algorithm, which in theory is suitable for problems with many irrelevant attributes.
The robustness of Winnow to high dimensional feature space is therefore considered an important reason why it is suitable for NLP tasks.
A second problem for the original Winnow method is that it does not produce a reliable estimate on the confidence of its prediction.

 Perceptron, Winnow, and PAC Learning   (Site not responding. Last check: 2007-10-11)
We analyze the performance of the widely studied Perceptron and Winnow algorithms for learning linear threshold functions under Valiant's probably approximately correct (PAC) model of concept learning.
We show that under the uniform distribution on boolean examples, the Perceptron algorithm can efficiently PAC learn nested functions (a class of linear threshold functions known to be hard for Perceptron under arbitrary distributions) but cannot efficiently PAC learn arbitrary linear threshold functions.
We also prove that Littlestone's Winnow algorithm is not an efficient PAC learning algorithm for the class of positive linear threshold functions, thus answering an open question posed by Schmitt [ Neural Comput., 10 (1998), pp.

 MERL – Context-Sensitive Spelling Correction
A completely different technology is needed here: one that analyzes the context to decide whether the observed word is plausible in that context, or whether some other word is more likely to have been intended.
Both methods have achieved predictive accuracies in the 90-100% range (depending on the spelling error); the accuracies of the Winnow-based method are the highest reported in the literature.
In addition, we introduce two enhancements to the basic Winnow algorithm: (1) Two-layer architecture: embed Winnow in a two-layer ensemble-of-classifiers architecture; and (2) Sparse network: build links connecting Winnow to its inputs in a lazy fashion.

We argue that the Winnow family of algorithms is particularly suitable for solving classification problems arising from NLP applications, due to their robustness to irrelevant features.
However in theory, Winnow may not converge for linearly non-separable data.
To remedy this problem, we employ a generalization of the original Winnow method.

 MERL – TR1996-007 – Applying Winnow to Context-Sensitive Spelling Correction
Multiplicative weight-updating algorithms such as Winnow have been studied extensively in the COLT literature, but only recently have people started to use them in applications.
This is the task of fixing spelling errors that happen to result in valid words, such as substituting to for too, casual for causal, and so on.
Previous approaches to this problem have been statistics-based; we compare Winnow to one of the more successful such approaches, which uses Bayesian classifiers.
