| ===Description=== | | ====Inputs==== |
|
| |
|
| Generate a table which summarizes the performance of a set of input models, and also shows their relevant input parameters and options. This is useful for comparing the quality of a set of models.
| | * '''x''' = 3 element vector where x(1) = coefficient, x(2) = offset and x(3) is equal to the decay constant |
| The table shows:
| |
| * Parameters- parameters and important options from each model (LVs, PCs, gamma, number of points, etc). | |
| * Statistics: (RMSEC/CV/P, # of support vectors, classification error rates as False Pos/Neg Rate average over classes. In all cases, value must be a single value for a given model (no vectors). Models which are not in the supported model list are ignored (see getallowedmodeltypes).
| |
|
| |
|
| ====Inputs====
| |
| * '''models''' = a cell array containing one or more models.
| |
|
| |
|
| ====Outputs==== | | ====Outputs==== |
| * '''columnkeys''' = 1 x ncolumn cell array containing keys identifying table columns in order.
| |
| * '''columnlabels''' = 1 x ncolumn cell array containing descriptive labels for table columns in order.
| |
| * '''tablevalues''' = nmodel x ncolumn cell array containing values.
| |
|
| |
|
| ===Options===
| |
|
| |
|
| options = a structure array with the following fields:
| |
| * '''display''': [ 'off' | {'on'} ] governs level of display to command window.
| |
| * '''plots''': [ 'final' | {'none'} ] governs level of plotting.
| |
| * '''category''': [ {'all'} | 'classification' | 'regression' | 'decomposition' ] restrict output to models of this category type, or all.
