The architecture consists of two main paths: the contracting path and the expanding path. #### Contracting Path The contracting path is responsible for extracting features from input data and compressing them into a lower-dimensional representation. This path involves several layers of processing, including convolutional layers, pooling layers, and normalization layers. The convolutional layers apply filters to the input data to detect patterns and features relevant to energy market dynamics. Pooling layers reduce the spatial dimensions of the data, allowing the network to focus on the most significant features. Normalization layers ensure that the data maintains a consistent scale, improving the stability and convergence of the network during training. #### Expanding Path The expanding path is designed to reconstruct the compressed representation back into a higher-dimensional output, facilitating decision-making and optimization processes. This path includes deconvolutional layers, upsampling layers, and activation layers. Deconvolutional layers reverse the effects of convolutional layers, expanding the feature maps to their original dimensions. Upsampling layers increase the spatial resolution of the data, enabling finer granularity in decision-making. Activation layers apply non-linear transformations to the data, introducing complexity and enabling the network to model intricate relationships within the energy market. The contracting and expanding paths work in tandem to process input data efficiently, extract meaningful features, and generate outputs that inform energy market optimization and real-time power trading decisions. This architecture ensures scalability, robustness, and adaptability in dynamic environments, leveraging the strengths of multi-agent systems to deliver a comprehensive solution. ## Results Summary The experimental results demonstrate the effectiveness of the proposed multi-agent system framework for energy market optimization and real-time power trading. The framework, which integrates the Counterfactual Energy Planner with specialized modules, shows significant improvements over state-of-the-art (SOTA) methods across multiple datasets and metrics. ### Experimental Results **Table 1.** Comparison of our method with SOTA methods on Energy Market Transactions Dataset and Real-Time Power Trading Records | Model | Energy Market Transactions Dataset | Real-Time Power Trading Records ||------------------------------|------------------------------------|---------------------------------|| | Accuracy | Precision | Recall | AUC | Accuracy | Precision | Recall | AUC || Flamingo Qian et al.
