Interface OraPredictTask

All Superinterfaces:

javax.datamining.MiningObject, OraPredictiveAnalyticsTask, javax.datamining.base.Task

public interface OraPredictTask

extends OraPredictiveAnalyticsTask

OraPredictTask used to produce predictions for the specified target column in the input dataset as predictions output table. The input consists of a table that has case id column, other predictor columns and a target column. The target column containing the values to predict. The input data must contain some cases in which the target value is known (that is, is not NULL). Cases where the target values are known are used to train models.

Predictions output table has the following fixed columns:

• case_id VARCHAR2 or NUMBER
• • Each of the cases identified in the case_id column. This is the same as the name that was passed in. The data type is the same as input case_id type.
• prediction VARCHAR2 or NUMBER
• • The predicted value of the target column for the given case. The data type is the same as the input target_column_name type.
• probability NUMBER
• • For classification (categorical target), the probability of the top prediction. For regression problems (numerical target), this column contains NULL.

Predictions are returned for all cases in the input data. Predicted values for known cases may be interesting in some situations, for example, to perform deviation analysis, that is, to compare predicted values and actual values.

Method Summary

java.lang.String	getInputData() Returns the input data URI of the predict.
java.lang.String	getOutputData() Returns the output data URI.
java.lang.String	getTargetAttributeName() Returns the target column
void	setInputData(java.lang.String dataURI, java.lang.String caseID) Set the URI for the predict task input data and case identifier to uniquely identify each case.
void	setOutputData(java.lang.String dataURI) Sets the output data URI of the predict.
void	setTargetAttributeName(java.lang.String targetAttributeName) Sets the target column to be used for prediction.
