Outline

This study evaluates the performance of classical and quantum-inspired sequential models for univariate time series prediction of received SMS activity using the Milan Telecommunications Activity dataset. Due to data limitations, we focus only on SMS reception signals for each spatial grid cell. Five models are compared under various input sequence lengths (4, 8, 12, 16, 32, and 64). All models are trained to predict SMS reception values for the next 10 minutes based solely on past values within a given sequence window. The results indicate that different models exhibit varying sensitivity to sequence length, suggesting that quantum enhancement is not universally beneficial. Rather, the effectiveness of quantum modules is highly dependent on the specific task and architecture design, reflecting inherent trade-offs between model size, parameterization strategy, and temporal modeling capabilities.

Takeaways, Limitations

Takeaways: This shows that quantum-inspired models do not always outperform classical models, and that model performance can vary depending on sequence length and model architecture. The application of quantum computing suggests that the effectiveness may vary depending on the specific problem and architecture. It emphasizes the need to consider trade-offs between model size, parameterization strategy, and temporal modeling capabilities.
Limitations: Due to data limitations in the Milan Telecommunications Activity dataset, only SMS reception signals were analyzed; SMS transmission signals were not considered. Generalizability to other types of communication data or other datasets may be limited.
