Abstract

We describe a neural implementation of the combination of weak classifiers (CWC) algorithm [Ji and Ma, 1997] which is able to learn the one-step-look-ahead task where the input is natural language sentences. The one-step-look-ahead task is more usually implemented with Simple Recurrent Networks [Elman, 1990] whose architecture typically consists of comparitively few neurons but learning requires many thousands of presentations of the training data. Our implementation includes a four layered architecture which consists of (1) an input layer having one neuron for each category, (2) an internally recurrent layer which captures the dynamics of the temporal input, (3) a large hidden layer of weakly classifying perceptrons and (4) a winner-take-all output layer having the same number of neurons as the input.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
