– Layer 1: the sample selection procedure, which partitions the data sample
S into subsamples (one for each of the processors available)
– Layer 2: For each processor there is a corresponding learning algorithm
Li which runs on the corresponding subsample Si and generates a concept
description Ci.
– Layer 3: the concept descriptions are then merged by a combining procedure
to form a final concept description Cfinal (such as a set of classification
rules).
The model allows for the learning algorithms Li to communicate with each
other but does not specify how.
