ExtraTree

An Extra Tree is the randomized variant of a Decision Tree. It can also be used for the prediction of values (regression) or classes (classification).

Supported properties

Classification limitation

With classification models, only the output of the labels is mapped in the PLC. The scores/probabilities are not available in the PLC.

Supported data types

A distinction must be made between "supported datatype" and "preferred datatype". The preferred datatype corresponds to the precision of the execution engine.

The preferred datatype is floating point 64 (E_MLLDT_FP64-LREAL).

When using a supported datatype, an efficient type conversion automatically takes place in the library. Slight losses of performance can occur due to the type conversion.

A list of the supported datatypes can be found in ETcMllDataType.
