Uno dei motivi per cui l'interfaccia visuale di SPSS Modeler è così semplice da apprendere è che ogni nodo ha una funzione chiaramente definita. Tuttavia, per l'elaborazione complessa può essere necessaria una lunga sequenza di nodi Alla fine, questo può ingombrare la tua area di flusso e rendere difficile seguire i diagrammi di flusso.
Ci sono due modi per evitare l'ingombro di un flusso lungo e complesso:
È possibile suddividere una sequenza di elaborazione in diversi flussi. Il primo flusso, ad esempio, crea un file di dati che il secondo utilizza come input. Il secondo crea un file di dati utilizzato dal terzo come input e così via. Tuttavia, ciò richiede la gestione di più flussi.
È possibile creare un SuperNode come alternativa più semplice quando si utilizzano processi di flusso complessi. I SuperNodes raggruppano più nodi in un singolo nodo incapsulando sezioni di flusso. Ciò fornisce vantaggi al data miner:
Il raggruppamento dei nodi risulta in un flusso più ordinato e più gestibile.
I nodi possono essere combinati in un Supernodo specifico per un settore di business.
Per raggruppare i nodi in un gruppo SuperNode:
Tenere premuto Ctrl e fare clic sui nodi che si desidera raggruppare.
Fare clic su Crea SuperNode.
I nodi sono raggruppati in un singolo SuperNode con una speciale icona a stella.Figura 1. icona SuperNode
