Leider kann ich als Text-basiertes KI-Modell keine Bilder generieren. Um dir trotzdem weiterzuhelfen, kann ich dir basierend auf dem Kontext und den Informationen aus dem Paper eine textuelle Beschreibung der Architektur des Hybridmodells liefern. Diese Beschreibung kannst du dann verwenden, um die Abbildung selbst zu erstellen, z.B. mit einem Grafikprogramm wie draw.io oder Lucidchart. **Architektur des CNN-LSTM-Transformer-Hybridmodells:** Das Modell besteht aus folgenden Schichten: 1. **Eingabeebene (Input Layer):** Nimmt die Sequenzdaten des PeMS-Datensatzes entgegen, z.B. Verkehrsfluss, Durchschnittsgeschwindigkeit und Belegung für mehrere Zeitschritte. 2. **Faltungsschicht (Convolutional Layer):** Wendet 1D-Faltungsfilter auf die Eingabesequenz an, um lokale räumliche Merkmale zu extrahieren. 3. **Max-Pooling-Schicht (Max Pooling Layer):** Reduziert die Dimensionalität der gefalteten Merkmale, behält aber die wichtigsten Informationen bei. 4. **Bidirektionale LSTM-Schicht (Bidirectional LSTM Layer):** Verarbeitet die Sequenzdaten in beide Richtungen (vorwärts und rückwärts), um sowohl vergangene als auch zukünftige Abhängigkeiten zu erfassen. 5. **Transformer-Blöcke (Transformer Blocks):** Modellieren langfristige Abhängigkeiten innerhalb der Sequenzdaten mithilfe von Selbstaufmerksamkeitsmechanismen. 6. **Globale Durchschnittspooling-Schicht (Global Average Pooling Layer):** Fasst die Merkmale aus den Transformer-Blöcken zu einem Vektor fester Länge zusammen. 7. **Ausgabeschicht (Output Layer):** Gibt die vorhergesagten Werte für den Verkehrsstaus aus, z.B. den Verkehrsfluss für die nächsten 12 Zeitschritte. Die Verbindungen zwischen den Schichten und die Anzahl der Neuronen in jeder Schicht können je nach den spezifischen Anforderungen des Modells angepasst werden. Ich hoffe, diese Beschreibung hilft dir bei der Erstellung deiner Abbildung! ==================================================
