These configuration properties enable you to tune the built-in learning module.

confidenceLevel

Description

A percentage indicating how confident you want the learning utility to be before switching from exploration to exploitation. A value of 0 effectively shuts off exploration.

This property is applicable if the Interact > offerserving > optimizationType property for Unica Interact runtime is set to BuiltInLearning only.

Default value

95

Valid Values

An integer between 0 and 95 divisible by 5 or 99.

validateonDeployment

Description

If set to No, Unica Interact does not validate the learning module when you deploy. If set to yes, Unica Interact validates the learning module when you deploy.

Default value

No

Valid Values

Yes | No

maxAttributeNames

Description

The maximum number of learning attributes the Unica Interact learning utility monitors.

This property is applicable if the Interact > offerserving > optimizationType property for Unica Interact runtime is set to BuiltInLearning only.

Default value

10

Valid Values

Any integer.

maxAttributeValues

Description

The maximum number of values the Unica Interact learning module tracks for each learning attribute.

This property is applicable if the Interact > offerserving > optimizationType property for Unica Interact runtime is set to BuiltInLearning only.

Default value

5

otherAttributeValue

Description

The default name for the attribute value used to represent all attribute values beyond the maxAttributeValues.

This property is applicable if the Interact > offerserving > optimizationType property for Unica Interact runtime is set to BuiltInLearning only.

Default value

Other

Valid Values

A string or number.

Example

If maxAttributeValues is set to 3 and otherAttributeValue is set to other, the learning module tracks the first three values. All of the other values are assigned to the other category. For example, if you are tracking the visitor attribute hair color, and the first five visitors have the hair colors black, brown, blond, red, and gray, the learning utility tracks the hair colors black, brown, and blond. The colors red and gray are grouped under the otherAttributeValue, other.

percentRandomSelection

Description

The percent of the time the learning module presents a random offer. For example, setting percentRandomSelection to 5 means that 5% of the time (5 out of every 100 recommendations), the learning module presents a random offer, independent of the score. Enabling percentRandomSelection overrides the offerTieBreakMethod configuration property. When percentRandomSelection is enabled, this property is set regardless if learning is on or off or if built-in or external learning is used.

Default value

5

Valid Values

Any integer from 0 (which disables the percentRandomSelection feature) up to 100.

recencyWeightingFactor

Description

The decimal representation of a percentage of the set of data defined by the recencyWeightingPeriod. For example, the default value of .15 means that 15% of the data used by the learning utility comes from the recencyWeightingPeriod.

This property is applicable if the Interact > offerserving > optimizationType property for Unica Interact runtime is set to BuiltInLearning only.

Default value

0.15

Valid Values

A decimal value less than 1.

recencyWeightingPeriod

Description

The size in hours of data granted the recencyWeightingFactor percentage of weight by the learning module. For example, the default value of 120 means that the recencyWeightingFactor of the data used by the learning module comes from the last 120 hours.

This property is applicable only if optimizationType is set to builtInLearning.

Default value

120

minPresentCountThreshold

Description

The minimum number of times an offer must be presented before its data is used in calculations and the learning module enters the exploration mode.

Default value

0

Valid Values

An integer greater than or equal to zero.

enablePruning

Description

If set to Yes, the Unica Interact learning module algorithmically determines when a learning attribute (standard or dynamic) is not predictive. If a learning attribute is not predictive, the learning module will not consider that attribute when determining the weight for an offer. This continues until the learning module aggregates learning data.

If set to No, the learning module always uses all learning attributes. By not pruning non-predictive attributes, the learning module may not be as accurate as it could be.

Default value

Yes

Valid Values

Yes | No
