### User Behaviour Analysis
The notification response analysis module could implement high-precision real-time monitoring of user-system interactions, extending established IoT monitoring architectures [18; 63]. The module would be designed to capture response latencies with millisecond resolution, implementing categorical classification by notification characteristics (e.g., completion alerts and overstay warnings) and criticality levels [3; 19]. Response pattern modeling may employ advanced survival analysis techniques, enabling probabilistic prediction of response intervals through the integration of historical behavioral data and contextual parameters [26; 83]. Module predictions will probably rely on gradient-boosted decision trees (GBDT), considered for their demonstrated efficacy in charging infrastructure applications [24; 29]. The GBDT architecture could provide optimal handling of feature interactions, robust performance with non-linear relationships, and effective management of outlier effects. System performance targets may include high accuracy in response prediction within an appropriate time window after notifications [6; 28]. This predictive capability could enable the implementation of adaptive engagement strategies, including progressive notification protocols and dynamic incentive adjustments [7]. The predictive modeling framework proposes to implement an ensemble architecture integrating multiple analytical methodologies [29; 50]. This hybrid system could combine supervised and unsupervised learning paradigms with the goal of maximizing analytical capabilities [3; 46]. The analytical pipeline architecture would emphasize modularity and adaptability, incorporating three primary components: temporal pattern analysis, behavioral clustering, and anomaly detection. This structure reflects recent advances in charging behavior analysis [24; 26], aiming for robust pattern identification across multiple temporal scales while maintaining system adaptability to emerging behavioral trends. The model is expected to implement online learning capabilities, continuously updating model parameters as new behavioural data becomes available, thus adapting to evolving user behaviours and improving long-term accuracy. Predictive accuracy could be improved by integrating multi-dimensional contextual data, including environmental conditions, event schedules, and grid utilization patterns [29; 50]. We propose an advanced feature fusion architecture using attention mechanisms for optimal data source integration, a technique showing superior performance in recent EV charging analyses [3; 24]. This architecture could enable adaptive weight ing of information streams based on their predictive significance for specific behavioral patterns [26; 28]. The system architecture could also incorporate a scalability framework to accommodate expanding user bases and charging infrastructure. The distributed architecture, described in Section 4.1, could allow for efficient horizontal scaling through optimized workload distribution. Privacy preservation can be achieved through edge-layer data anonymization protocols, ensuring secure handling of personally identifiable information before cloud transmission. This multi-tiered approach is intended to balance computational efficiency with robust privacy protection, enabling system growth while maintaining operational security.
