An Eecient Multiprocessor Mapping Algorithmfor the Kohonen Feature Map and Its Derivative Models Contents 1 Introduction 1 2 Computational Parallelism in the Kohonen Model 1 3 Homogenous Multi-processor Architecture 2

This paper explores the potential for utilising specialised hardware for the implementation of the Kohonen model and its derivative models. The adaptation periods of these algorithms is potentially protracted and computationally expensive; especially for the Adaptive Kohonen model in real-world, on-line applications. This paper analyses these models and highlights inherent parallelism. This ana...

Investigating the Effects of Hardware Parameters on Power Consumptions in SPMV Algorithms on Graphics Processing Units (GPUs)

Although Sparse matrix-vector multiplication (SPMVs) algorithms are simple, they include important parts of Linear Algebra algorithms in Mathematics and Physics areas. As these algorithms can be run in parallel, Graphics Processing Units (GPUs) has been considered as one of the best candidates to run these algorithms. In the recent years, power consumption has been considered as one of the metr...

Directional Stroke Width Transform to Separate Text and Graphics in City Maps

One of the complex documents in the real world is city maps. In these kinds of maps, text labels overlap by graphics with having a variety of fonts and styles in different orientations. Usually, text and graphic colour is not predefined due to various map publishers. In most city maps, text and graphic lines form a single connected component. Moreover, the common regions of text and graphic lin...

A Simple Robust Robotic Vision System using Kohonen Feature Mapping

We use a one-dimensional Kohonen network for detecting the angular position of an infrared beacon in front of an experimental autonomous vehicle. The inputs to the Kohonen network are the analog output signals from eight infrared detectors arranged along a semicircle on the front of the vehicle. By letting the network self-organise while a beacon is moved from one side to the other in front of ...
