The result of these tests together provide the performance of the model. Sometimes, in extreme cases, the test set can have only one example, and this is called the leave-one-out procedure (Efron 1983; Kohavi 1995).

Ideally, in the scientific community, one would like to develop accurate, physicallybased models for the physical system being studied. This model serves as a hypothesis for our current understanding of the physical system and as a basis for extracting desired vegetation variables from other readily known/measured variables. These physically-based models are forced to address the entire radiative transfer problem which includes a large number of variables. In remote sensing applications many of these variables are not of interest.

To actually use physically-based models for extracting vegetation variables, the models must be inverted. In most cases these models are complex nonlinear systems which must be solved using numerical methods. The traditional approach employs numerical optimization techniques that, once initialised, search for the optimum parameter set that minimizes the error. There are difficulties in using these techniques. A stable and optimum inversion is not guaranteed and the technique can be computationally intensive when using complex radiative transfer models of vegetation.
