Options

The table below describes the options available for NonNegativeLogisticRegression.

Option

Description

batchSize

The preferred number of instances to process if batch prediction is being performed. More or fewer instances may be provided, but this gives implementations a chance to specify a preferred batch size.

debug

If set to true, classifier may output additional info to the console.

doNotCheckCapabilities

If set, classifier capabilities are not checked before classifier is built (Use with caution to reduce runtime).

numDecimalPlaces

The number of decimal places to be used for the output of numbers in the model.

numThreads

The number of threads to use, which should be >= size of thread pool.

poolSize

The size of the thread pool, for example, the number of cores in the CPU.

seed

The random number seed to be used.
