Visualisation of gait data with Kohonen self-organising neural maps.

Self-organising artificial neural networks were used to reduce the complexity of joint kinematic and kinetic data, which form part of a typical instrumented gait assessment. Three-dimensional joint angles, moments and powers during the gait cycle were projected from the multi-dimensional data space onto a topological neural map, which thereby identified gait stem-patterns. Patients were positio...

Using artificial neural networks for solving chemical problems Kohonen self-organising feature maps and Hopfield networks

This second part of a Tutorial on neural networks focuses on the Kohonen self-organising feature map and the Hopfield network. First a theoretical description of each type is given. The practical issues concerning applications of the networks are then discussed. For each network, a description is given of the types of problems which can be tackled by the specific neural network, followed by a p...

The automated classification of astronomical lightcurves using Kohonen self-organising maps

We apply the technique of self-organising maps (Kohonen 1990) to the automated classification of singly periodic astronomical lightcurves. We find that our maps readily distinguish between lightcurve types in both synthetic and real datasets, and that the resulting maps do not depend sensitively on the chosen learning parameters. Automated data analysis techniques are likely to be become increa...

Image Theft Detection with Self-Organising Maps

In this paper an application of the TS-SOM variant of the self-organising map algorithm on the problem of copyright theft detection for bitmap images is shown. The algorithm facilitates the location of originals of copied, damaged or modified images within a database of hundreds of thousands of stock images. The method is shown to outperform binary decision tree indexing with invariant frame de...

Structural damage identification in laminated structures using FRF data

A damage identification technique based on frequency response functions (FRF) sensitivities is presented. This technique leads to a set of linear equations, which is solved using an algorithm that constrains the solution to be physically admissible. Damage simulation and identification on a laminated rectangular plate is performed. The influence of the number of natural frequencies and mode sha...
