Cluster Aggregated GAN (CAG): A Cluster-Based Hybrid Model for Appliance Pattern Generation
TL;DR
A significant challenge in developing non-intrusive load monitoring algorithms is the lack of labeled synthetic appliance data. The Cluster Aggregated GAN (CAG) framework was developed to generate realistic load patterns by clustering appliances based on their behavior and using specialized generators.
✦ Why It Matters
Engineers can leverage CAG to generate high-fidelity synthetic appliance data for improved load monitoring solutions.
Key Takeaways
- Utilize CAG for improved synthetic load pattern generation.
- Implement clustering to enhance model interpretability and scalability.
- Adopt specialized generators for different appliance types.
- Leverage the UVIC dataset for benchmarking your models.
How It Works
CAG employs a clustering module to categorize appliances based on their activation patterns. For intermittent devices, it allocates dedicated generators to each cluster, ensuring that both common and rare usage patterns are effectively modeled.
Continuous appliances are handled by an LSTM-based generator, which captures gradual changes in usage over time, enhancing training stability through sequence compression.
