This produces a situation where different “species” of solution develop to exploit different “niches” of the problem – indicating exploitable solutions. It is argued that for context to be fully learnable a further step of abstraction is necessary. Such contexts abstracted from clusters of solution/model domains make sense of the problem of how to identify when it is the content of a model is wrong and when it is the context. Some principles of learning to identify useful contexts are proposed. date: 2001 date_type: published volume: 2116 publisher: Springer-verlag pagerange: 143-155 refereed: TRUE referencetext: Aha, D.
