unsupervised hypothesis is
where analysts do not create a model or hypothesis before running the analysis (hypothesis is created after the analysis)
cluster analysis is
(unsupervised technique)
statistical techniques identify groups of entities that have similar characteristics
ex find groups of similar customers from customer order and demographic data
what is supervised data mining?
developing a model prior to the analysis and apply statistical techniques to data to estimate parameters of the model (uses regression analysis)
Neural networks
supervised data mining application used to predict values and make classifications such as good prospect or bad prospect
