SPM offers some degree of automatic type detection when it reads a database, but this support may still require some additional effort on the part of a user. How SPM works depends on the file type being read:
The Salford Predictive Modelerâ„¢ suite (SPM) includes a number of automated tools to assist in the process of feature selection under the BATTERY mechanism. For example,
BATTERY KEEP
Selects a subset of features at random and builds a model from this random subset only. The GUI will guide you in how to use this option, but from the command line you would issue something like:
BATTERY KEEP=100, 15
Which requests 100 models, each of which includes 15 randomly-selected predictors. If we are sure that we want certain variables included in every such model, the command would look like:
BATTERY KEEP=100, 15 CORE= X1, X2, X3, X4, X5
