Albert Einstein
How do you segment/cluster observations over space?
Split a dataset into groups of observations that are similar within the group and dissimilar between groups, based on a series of attributes
Machine learning
The computer learns some of the properties of the dataset without the human specifying them
Unsupervised
There is no a-priori structure imposed on the classification → before the analysis, no observations is in a category
Different properties, different best usecases
See interesting comparison table
Unsupervised Spatial Machine Learning
Aggregating basic spatial units (areas) into larger units (regions)
Split a dataset into groups of observations that are similar within the group and dissimilar between groups, based on a series of attributes...
...with the additional constraint observations need to be spatial neighbors
See Duque et al. (2007) for an excellent, though advanced, overview
