Parameter
Types
EG Cluster-IT includes two types
of parameters - limiting and threshold. Limiting
parameters control what is taken into account in forming
clusters.
Threshold
parameters stop processing when specific events occur such as
when a specific number of clusters are reached or when a
cluster of a certain size is reached. Threshold parameters are
typically used in online applications.
Weighting
Points
Returning to the populated places
analogy, how can differing populations be handled? For
example, the Los Angeles area is comprised of many individual
cities with Los Angeles by far being the largest. In other
words, Los Angeles overwhelms all of the other cities in the
"area".
EG
Cluster-IT handles weighted points by including the weights
in the cluster calculations. In fact, in this Los Angeles
example, the resulting cluster for the Los Angeles area is
very close to the center of Los Angeles itself (as you might
expect.)
Versions
There are three versions of Cluster-IT
- The first version contains
the basic functionality.
- The second version adds
threshold capabilities.
- The third version adds a
32bit callable DLL.
