Quadrant crunching is an application of morphological analysis methodology, a systematic procedure for identifying all the potentially feasible combinations between several sets of variables. Quadrant crunching helps analysts avoid surprise by examining multiple possible combinations of selected key variables. It also helps analysts to identify and systematically challenge assumptions, explore the implications of contrary assumptions and discover “unknown unknowns. ” Quadrant crunching reduces the chance that events could play out in a way that has not previously been at least imagined and considered.  2, fiche 1, Anglais, - quadrant%20crunching

The alternative to depending on training sites for classification is to apply the concept of signature extension. This term refers to the assumption that a single, more or less constant, spectral signature may be defined as characteristic of any class, and that this signature has broad(universal) applicability to any scene in a region, or even worldwide. As a specific example, the signature for winter wheat at its maturation should be essentially the same for fields in the U. S. Great Plains, Argentina, the Ukraine, and Australia-provided such variables as differing air masses, Sun position, soil types, soil moisture, etc. are compensated for. If that proves true, then an unknown feature or class in a given scene anywhere should be classifiable by comparing its spectral properties(for a Landsat pixel, its multiband digital number [DN] values) to a "data bank" containing standard values for each of many classes. The closest fit of the unknown's DN [digital number] values to those of some one class in the bank is assumed to identify it.  3, fiche 3, Anglais, - signature%20extension

We will have to ... enable an intelligent machine to learn an entirely new domain of knowledge whenever it encounters one. Such a computer ... will be able to know that it doesn’t know something, so that it could seek an answer ... With this persistent knowledge of what we don’t know, we may be able to follow the Socratic path toward self-knowledge of our thought processes.  1, fiche 5, Anglais, - self%2Dknowledge
