![]() When one output is connected, another output port becomes available which is ready to deliver another output (if any). The Select Subprocess operator can have multiple outputs. Make sure that you have connected the right number of ports at all levels of the chain. The Object supplied at the first input port of the Select Subprocess operator is available at the first input port of the nested chain (inside the subprocess).Don't forget to connect all inputs in correct order. When one input is connected, another input port becomes available which is ready to accept another input (if any). The Select Subprocess operator can have multiple inputs. the gain by using different preprocessing steps or the quality of a certain learner. This might be useful in order to test different layouts, e.g. For example, if this operator is placed in any Loop operator and the select which parameter is controlled by a macro then this operator can be used to dynamically change the process setup. The true power of this operator comes into play when it is used with other operators like various Macro and Loop operators. If this operator is placed in any Loop operator this operator will be executed multiple number of times. Thus the subprocess to be executed can be controlled by using macros. Macros can be provided in the select which parameter. The process to be executed is selected by the select which parameter. You can easily add or remove subprocesses. The number of subprocesses can be easily controlled. The Select Subprocess operator consists of multiple subprocesses but it executes only one subprocess at a time. Subprocesses can have subprocesses in them just like folders can have folders in them. ![]() This works like files and folders work in operating systems. To go back to the parent process, click the blue-colored up arrow button in the Process View toolbar. Here you can see the options to add or remove subprocesses. The subprocesses are then shown in the same Process View. For more details about subprocesses please study the Subprocess operator.ĭouble-click on the Select Subprocess operator to go inside and view the subprocesses. ![]() That is why a subprocess can also be defined as a chain of operators that is subsequently applied. A subprocess can be considered as a small unit of a process, like in a process, all operators and combination of operators can be applied in a subprocess. Once the subprocess execution is complete, flow is returned to the process (the parent process). Whenever a subprocess is reached during a process execution, first the entire subprocess is executed. A subprocess introduces a process within a process. It is very important to have a good understanding of the use of subprocesses in RapidMiner to understand this operator completely. It is important to have a good understanding of subprocesses in order to use this operator effectively. This operator is similar to a switch, where numerous options exist but only one option is selected at a time. SynopsisThis operator consists of multiple subprocesses but it executes only one subprocess at a time.
