Proximity stigma: testing the hypothesis.

A Cross-Cultural Test of the Proximity Hypothesis

The Kohonen Self-Organizing Map (SOM) is an unsupervised learning technique for summarizing high-dimensional data so that similar inputs are, in general, mapped close to one another. When applied to textual data, SOM has been shown to be able to group together related concepts in a data collection and to present major topics within the collection with larger regions. This article presents research in which we sought to validate these properties of SOM, called the Proximity and Size Hypotheses, through a user evaluation study. Building upon our previous research in automatic concept generation and classification, we demonstrated that the Kohonen SOM was able to perform concept clustering effectively, based on its concept precision and recall7 scores as judged by human experts. We also demonstrated a positive relationship between the size of an SOM region and the number of documents contained in the region. We believe this research has established the Kohonen SOM algorithm as an intuitively appealing and promising neural-network-based textual classification technique for addressing part of the longstanding "information overload" problem.

There is a saying that “you can choose your friends, but not your family.” However, it may be that your choice of friends isn’t totally within your conscious control either. In a classic study of friendship formation, researchers asked nearly 300 MIT dormitory residents to list their closest friends. The researchers then looked at where the listed friends lived in the dorms.2 When someone lived one door away, there was a 41% likelihood they were listed as a close friend. As the number of doors increased, that likelihood decreased such that those living four doors away had only a 10% likelihood of being listed as a close friend. This study demonstrates the importance that proximity, or being physically near others, has on relationship formation. for an application of proximity to How I Met Your Mother.

None of the above theories or mechanisms that deal with proximate causation should, in principle, be incompatible with the present formulation that proposes a hypothesis at the level of ultimate causation.

It is further contended that such identification should facilitate our understanding of these phenomena and would open the way to a range of further hypotheses about proximate causal factors. It is suggested that it would be impossible to have a proper understanding of the dysfunction of any given biological system until the normal functioning of such a system (i.e. the purpose it serves for the organism) is correctly identified (Bolton & Hill, 1996).
