Tutorials are planned to take place on 21 October 2024. Here you can find a summary of each accepted tutorial. =============== Systems for Scalable Graph Analytics and Machine Learning =============== Da Yan (Indiana University Bloomington), Lyuheng Yuan (Indiana University Bloomington), Akhlaque Ahmad (Indiana University Bloomington) and Saugat Adhikari (Indiana University Bloomington) Graph-theoretic algorithms and graph machine learning models are essential tools for addressing many real-life problems, such as social network analysis and bioinformatics. To support large-scale graph analytics, graph-parallel systems have been actively developed for over one decade, such as Google’s Pregel and Spark’s GraphX, which (i) promote a think-like-a-vertex computing model and target (ii) iterative algorithms and (iii) those problems that output a value for each vertex. However, this model is too restricted for supporting the rich set of heterogeneous operations for graph analytics and machine learning that many real applications demand. In recent years, two new trends emerge in graph-parallel systems research: (1) a novel think-like-a-task computing model that can efficiently support the various computationally expensive problems of subgraph search; and (2) scalable systems for learning graph neural networks. These systems effectively complement the diversity needs of graph-parallel tools that can flexibly work together in a comprehensive graph processing pipeline for real applications, with the capability of capturing structural features. This tutorial will provide an effective categorization of the recent systems in these two directions based on their computing models and adopted techniques, and will review the key design ideas of these systems. =============== Fairness in Large Language Models: Recent Advances and Future =============== Thang Viet Doan (Florida International University), Zichong Wang (Florida International University), Minh Nhat Nguyen (Florida International University) and Wenbin Zhang (Florida International University) Large Language Models (LLMs) have demonstrated remarkable success across various domains but often lack fairness considerations, potentially leading to discriminatory outcomes against marginalized populations. On the other hand, fairness in LLMs, in contrast to fairness in traditional machine learning, entails exclusive backgrounds, taxonomies, and fulfillment techniques. In this tutorial, we give a systematic overview of recent advances in the existing literature concerning fair LLMs. Specifically, a series of real-world case studies serve as a brief introduction to LLMs, and then an analysis of bias causes based on their training process follows. Additionally, the concept of fairness in LLMs is discussed categorically, summarizing metrics for evaluating bias in LLMs and existing algorithms for promoting fairness. Furthermore, resources for evaluating bias in LLMs, including toolkits and datasets, are summarized. Finally, current research challenges and open questions are discussed. =============== Unifying Graph Neural Networks across Spatial and Spectral Domains =============== Zhiqian Chen (Mississippi State University), Lei Zhang (Virginia Tech) and Liang Zhao (Emory University) Over recent years, Graph Neural Networks (GNNs) have garnered significant attention. However, the proliferation of diverse GNN models, underpinned by various theoretical approaches, complicates model selection, as they are not readily comprehensible within a uniform framework. Early GNNs were implemented using spectral theory, while others were based on spatial theory. This divergence renders direct comparisons challenging. Moreover, the multitude of models within each domain further complicates evaluation. In this half-day tutorial, we examine state-of-the-art GNNs and introduce a comprehensive framework bridging spatial and spectral domains, elucidating their interrelationship. This framework enhances our understanding of GNN operations. The tutorial explores key paradigms, such as spatial and spectral methods, through a synthesis of spectral graph theory and approximation theory. We provide an in-depth analysis of recent research developments, including emerging issues like over-smoothing, using well-established GNN models to illustrate our framework's universality. =============== Tabular Data-centric AI: Challenges, Techniques and Future Perspectives =============== Yanjie Fu (Arizona State University), Dongjie Wang (University of Kansas), Hui Xiong (Hong Kong University of Science and Technology (Guangzhou)) and Kunpeng Liu (Portland State University) Tabular data is ubiquitous across various application domains such as biology, ecology, and material science.

Temporal Graph Neural Networks (TGNNs) have gained significant attention for their effectiveness in representing temporal graphs. However, TGNNs still face significant efficiency challenges in real-world low-resource settings. First, from a data-efficiency standpoint, training TGNNs requires sufficient temporal edges and data labels, which is problematic in practical scenarios with limited data collection and annotation. Second, from a resource-efficiency perspective, TGNN training and inference are computationally demanding due to complex encoding operations, especially on large-scale temporal graphs. Minimizing resource consumption while preserving effectiveness is essential. Inspired by these efficiency challenges, this tutorial systematically introduces state-of-the-art data-efficient and resource-efficient TGNNs, focusing on algorithms, frameworks, and tools, and discusses promising yet under-explored research directions in efficient temporal graph learning.
