This paper introduces a novel approach to graph embedding that leverages the temporal dynamics of graph relationships. Traditional graph embedding techniques often treat graphs as static structures, failing to capture the evolving nature of connections between nodes. Our method, Temporal Graph Embedding via Relational Dynamics (TGERD), employs recurrent neural networks (RNNs) to model the sequence of changes in relationships, effectively learning representations of nodes based on their temporal evolution. The core innovation lies in a weighted temporal graph convolution, where recent relationship changes are given higher priority, allowing the model to adapt to shifts in the graph's structure over time. We demonstrate that this approach significantly improves graph embedding quality compared to static embedding methods, particularly in scenarios where relationships are not static. The algorithm is designed for flexibility and can be applied to various graph datasets with evolving connections.

This paper proposes a novel approach to program error diagnosis and repair leveraging Graph Neural Networks (GNNs). Traditional methods for software defect detection and correction often rely on manual inspection or rule-based systems, which can be time-consuming, expensive, and prone to human error. Our approach transforms program code into a graph structure, representing dependencies between code elements. A GNN is then employed to learn these dependencies and identify patterns associated with errors. This learned representation enables automated diagnosis of errors, and crucially, the generation of potential repair code. We demonstrate the feasibility and effectiveness of this method through a conceptual framework and illustrate the potential benefits of automating this critical aspect of software development. The core claim of this work is the utilization of GNNs to analyze program code dependencies for automated error diagnosis and repair. The core mechanism involves representing code as a graph, utilizing GNNs to learn dependencies and error patterns, and generating repair code.

Modern power systems require increasingly flexible and responsive power conversion, driving the need for power converters with enhanced controllability and adaptability, where artificial intelligence (AI) plays a key role in enabling intelligent decision making, adaptive control and system level optimization. However, current AI applications in power systems remain largely restricted to cloud‐based post processing or device‐level demonstrations, lacking end‐to‐end hardware platforms that support the full pipeline from programming to deployment within a closed loop formed by physical converter hardware and AI modules. To address this gap, this paper proposes an edge AI‐powered power converter (EAI‐PC) hardware platform that utilizes locally deployed edge intelligence to establish bidirectional data exchange between converter low‐level control and EAI upper‐layer command dispatch. The platform features an end‐to‐end AI‐to‐converter closed‐loop deployment framework, enabling AI‐generated commands to be directly executed on physical converter hardware. By interconnecting converters (AC/DC and DC/DC) with an EAI module (using NVIDIA Jetson Orin Nano) via an industrial CAN protocol, this platform supports hardware‐level algorithm verification in the power system domain. The proposed EAI‐PC platform is experimentally evaluated across system configurations from single to multiple interconnected converters, assessing converter performance, command delivery and three AI deployment cases (two offline and one online): a multilayer perceptron (MLP) for power‐sharing prediction, a spatio‐temporal graph neural network (STGNN) for photovoltaic (PV) and load forecasting, and a bidirectional long short‐term memory (Bi‐LSTM) for online battery dispatch in load management and peak shaving.

Biological regulatory networks (BRNs) govern cellular processes with inherent stochasticity, reflecting the probabilistic nature of gene expression and protein interactions. Traditional Graph Neural Networks (GNNs) often treat these networks as deterministic, leading to inaccurate representations and predictions. This work proposes a novel framework for modeling BRNs that explicitly incorporates stochasticity. We introduce probabilistic layers within a GNN architecture to represent the uncertainty in network dynamics, drawing inspiration from stochastic differential equations (SDEs). These layers allow the GNN to learn and propagate probabilistic information, capturing the random fluctuations observed in biological systems. Our approach provides a more realistic and robust model of BRNs, offering potential improvements in predicting network behavior and identifying key regulatory nodes. The core claim is to develop GNN architectures that can explicitly model the stochastic nature of biological regulatory networks, accounting for the inherent randomness in gene expression and protein interactions. The core mechanism involves introducing probabilistic layers within the GNN to represent the uncertainty in the network's dynamics, incorporating elements of stochastic differential equations. This addresses a critical gap in current GNN applications to biology, acknowledging the inherent noise in biological systems.

This paper presents a novel approach to dependency discovery within software systems, leveraging topological information derived from program code. The core idea is to automatically uncover complex dependencies between programs by analyzing control flow graphs, data dependencies, and abstract syntax trees (ASTs). A graph neural network (GNN) algorithm is developed to learn program representations and infer dependencies using graph convolutional operations. Furthermore, execution data is utilized to validate and refine the dependency graph. This method overcomes limitations of existing static analysis and monitoring-based tools by effectively utilizing program abstract representations, enabling the discovery of intricate dependencies often missed by traditional approaches. The research contributes to a more complete understanding of software ecosystems and facilitates improved dependency management, version control, and software evolution.

This paper introduces a novel approach to graph embedding that explicitly models the temporal dynamics of relationships within a graph. Current graph embedding techniques often treat graphs as static structures, neglecting the crucial aspect of how connections evolve over time. This work addresses this limitation by leveraging recurrent neural networks (RNNs) to process sequences of graph snapshots, learning embeddings that capture the directional, strength, and frequency changes in relationships. The core idea is to represent not just the current state of the graph, but the *process* of its evolution. We propose using weighted temporal convolution to capture nuanced changes in the graph's relational dynamics. The resulting embeddings are expected to be more informative and robust for downstream graph-based tasks compared to static embeddings.

The optimization of computational graphs is a critical step in deploying machine learning models, particularly deep neural networks. Traditional manual optimization methods are labor-intensive, require deep domain expertise, and are prone to human error. This paper proposes a novel approach leveraging program synthesis techniques to automate the process of computational graph optimization. The core idea is to treat computational graph optimization as a program synthesis problem, where a synthesis engine generates efficient execution plans based on the graph's structure, target hardware specifications, and performance constraints. We introduce a framework that translates performance objectives (e.g., minimizing latency, maximizing throughput) into formal synthesis targets. The system employs a combination of constraint solving, search algorithms, and potentially machine learning to explore the space of possible execution plans and identify the optimal one. This approach promises to significantly reduce the time and effort required for optimization, improve the accuracy of the resulting plans, and facilitate the deployment of complex models on diverse hardware platforms. The key contribution lies in applying program synthesis to a traditionally manual and complex optimization task, opening new avenues for automated and adaptive model deployment.

This paper introduces a novel approach to modeling complex systems utilizing multi-scale graph neural networks (MS-GNNs). Complex systems, characterized by interconnected components operating at varying scales, pose significant challenges for traditional modeling techniques. This research proposes a framework that decomposes a complex system into sub-systems defined by their respective scales. Each sub-system is then represented as a graph, and a graph neural network (GNN) is applied to learn patterns and relationships within that scale. A key innovation lies in the multi-scale fusion mechanism, which intelligently integrates information from these GNNs at different scales, ultimately constructing a comprehensive representation of the entire system. The core claim is the design of an MS-GNN capable of capturing the interconnectedness of complex systems across multiple scales, facilitating accurate modeling and prediction. The proposed methodology offers a fundamentally new approach combining the strengths of graph neural networks and multi-scale analysis, paving the way for improved understanding and prediction of complex phenomena.

This paper proposes a novel approach to neural network architecture generation, termed "Neuron Circuitry Driven Dynamic Program Generation." The core claim is that comprehensive analysis of large-scale neuron circuits can automatically generate highly optimized neural network architectures and connection weights tailored to specific tasks, surpassing the capabilities of traditional manual design or search-based methods. The proposed method leverages deep learning to train multiple large networks, extracting detailed neuron circuit maps (s1, s2, ..., sK) representing neuron connections – including connection strength, direction, and type. Graph Neural Networks (GNNs) are then employed to learn and reason from these circuit maps, identifying optimal connection patterns and architectural features for a given task. The resulting neural network architectures are dynamic, adapting in real-time to input data and task requirements for continuous self-optimization. This approach represents a significant departure from existing methods, which typically rely on static architectures or static search, by directly learning and utilizing biological neuron circuit maps through GNN modeling and inference, offering the potential for substantially improved neural network performance and efficiency.
