A Comparison Between the Proportional Keen Approximator and the Neural Networks Learning Methods

The Proportional Keen Approximation method is a young learning method using the linear approximation to learn hypothesis. In the paper this methodology will be compared with another well-established learning method i.e. the Artificial Neural Networks. The aim of this comparison is to learn about the strengths and the weaknesses of these learning methods regarding different properties of their learning process. The comparison is made using two different comparison methods. In the first method the algorithm and the known behavioural model of these methods are analysed. Later, using this analysis, these methods are compared. In the second approach, a reference dataset that contains some of the most problematic features in the learning process is selected. Using the selected dataset the differences between two learning methods are numerically analysed and a comparison is made.
