Activity 16: Neural Networks

Similar to the previous activity, Activity 16 is an extension of Activity 14. Here, we again use the features that we were able to extract in activity 14. However, unlike activity 14 and 15 where we used minimum distance classification and least discriminant analysis to determine class membership, in this activity what we'll use is neural networks.

A neural network is a computational model of how neurons in the brain work. It is one of the preferred method in pattern recognition for one does not need heuristics and recognition rules to perform classification. In this method, neural network "learn" the rules of mapping by example. [1]
For this activity what we want to do is to train the neural network with the training set for each class. The neural network should learn the "characteristic" feature of a specific class. To be able to perform this, we used the Artificial Neural Network toolbox for Scilab. We utilized the code posted in Cole Fabros' AP186 blog. Assigning the learning rate be equal to 0.1, 0 for the error tolerated by the network run for 1000 cycles the results are the following..

The first column is the expected class

An article in Rolling Stone (October 20, 1994) by Adam Miller called J. Philippe Rushton a 'professor of hate,' someone who 'takes money from an organization with a terrible past' (the Pioneer Fund, a foundation said to have an orientation toward eugenics). He is accused of being 'obsessed with intelligence and genetics' to the point of having 'racist' attitudes by Jeffrey Rosen and Charles Lane in The New Republic symposium on IQ (October 31, 1994). They single out Rushton for linking ethnocentricism to genetic factors; this in turn subjects him to the broad brush of being, along with Richard J. Herrnstein and Charles Murray, 'Neo-Nazis' Newsweek (October 24, 1994). In The Chronicle of Higher Education (October 26, 1994) critiquing Herrnstein and Murray's The Bell Curve it is clear...
