SoleModels.parse_orange_decision_list — Function

parse_orange_decision_list(decision_list, ignoredefaultrule = false; featuretype = SoleData.VariableValue)

Parser for orange-style decision lists. Reference: https://orange3.readthedocs.io/projects/orange-visual-programming/en/latest/widgets/model/cn2ruleinduction.html

Arguments

decision_list is an AbstractString containing the orange-style representation of a decision list;
ignoredefaultrule is an optional, Boolean parameter indicating whether to use the default rule as the default rule for the resulting decision list. When false, the last rule is ignored, and the second last is used as the default rule;
featuretype specifies the feature type used in the parsed ScalarConditions.
