This section describes various methods to
specify the number of association or sequence rules and define rule
properties such as support, confidence and maximum rule length.
You can control the number of association rules or sequence rules
to be created in one of the following ways:
- Specifying the number of rules to be created
- Specifying values for rule properties
You can specify the number of rules to be created by using the
method DM_RuleFilter..DM_setMaxNumRules. With this
method, you can specify the number of rules that you want to be included
in the associations models or the sequence rules models.
You can also control the number of rules by specifying the following
rule properties:
- Minimum support
- Minimum confidence
- Maximum rule length
You can specify these rule properties by using the methods
DM_setMinSupport,
DM_setMinConf,
or
DM_setMaxLen.
Note: Do not you use the method DM_Rulefilter and
the methods DM_setMinSupport, DM_setMinConf,
or DM_setMaxLen in the same mining settings because
the method DM_Rulefilter overwrites the constraints
that you specified with the other methods.
