EXPERIMENTS WITH SIMPLE HEBBIAN-BASED LEARNING RULES IN PATTERN CLASSIFICATION TASKS
George F. Harpur and Richard W. Prager
This report presents a neural network architecture which performs pattern classification using a simple form of learning based on the Hebb rule. The work was motivated by the desires to decrease computational complexity and to maintain a greater degree of biological plausibility than most other networks designed to perform similar tasks. A method of pre-processing the inputs to provide a distributed representation is described. A scheme for increasing the power of the network using a layer of `feature detectors' is introduced: these use an unsupervised competitive learning scheme, again based on Hebbian learning. Simulation results from testing the networks on two `real-world' problems are presented, and compared to those produced by other types of neural network.
If you have difficulty viewing files that end
which are gzip compressed, then you may be able to find
tools to uncompress them at the gzip
If you have difficulty viewing files that are in PostScript, (ending
'.ps.gz'), then you may be able to

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
