Method Detail

setBatchSize

void setBatchSize(String size)

Set the batch size to use. The implementer will prefer (but not necessarily expect) this many instances to be passed in to distributionsForInstances().

Parameters:

size - the batch size to use

getBatchSize

String getBatchSize()

Get the batch size to use. The implementer will prefer (but not necessarily expect) this many instances to be passed in to distributionsForInstances(). Allows the preferred batch size to be encapsulated with the client.

Returns:

the batch size to use

distributionsForInstances

double[][] distributionsForInstances(Instances insts)
                                     throws Exception

Batch scoring method

Parameters:

insts - the instances to get predictions for

Returns:

an array of probability distributions, one for each instance

Throws:

Exception - if a problem occurs
