Method Detail

exists

public java.util.Optional<java.lang.Double> exists(ai.libs.hasco.model.ComponentInstance composition,
                                                   ai.libs.jaicore.ml.cache.ReproducibleInstances reproducibleInstances,
                                                   ai.libs.jaicore.ml.cache.ReproducibleInstances testData,
                                                   java.lang.String className)

Checks whether there is an entry for the composition and corresponding evaluation specified by the reproducable instances. If so, it returns the corresponding performance score.

Parameters:

composition - - Solution composition.

reproducableInstances - - Instances object that includes the trajectory, i.e. all operations that have been applied to the instances like loading, splitting etc.

testData - - The reproducible instances of the test data used for this evaluation process

className - - the java qualified class name of the loss function that was used

Returns:

opt - Optional that contains the score corresponding to the composition and the reproducible instances or is empty if no suiting entry is found in the database.

store

public void store(ai.libs.hasco.model.ComponentInstance composition,
                  ai.libs.jaicore.ml.cache.ReproducibleInstances reproducibleInstances,
                  ai.libs.jaicore.ml.cache.ReproducibleInstances testData,
                  double score,
                  java.lang.String className,
                  long evaluationTime)

Stores the composition, the trajectory and the achieved score in the database.

Parameters:

composition - - Solution composition

reproducableInstances - - Instances object that includes the trajectory, i.e. all operations that have been applied to the instances like loading, splitting etc.

testData - - The reproducible instances of the test data used for this evaluation process

score - - Score achieved by the composition on the reproducible instances

className - - The java qualified class name of the loss function that was used

evaluationTime - - The time it took for the corresponding evaluation in milliseconds
