Graph Embedding
SIGEM: A Simple yet Effective Similarity based Graph Embedding Method
This paper introduces SIGEM, a novel self-supervised and contrastive-free graph embedding method. It proposes LINOW, a recursive link-based similarity measure, applicable to both directed and undirected graphs, with efficient matrix form computation and scalable variants (LINOW-sn, LINOW-bn). SIGEM uses LINOW-bn to compute node similarity, ranks nodes, and employs a single-layer neural network with an LLTR loss function to preserve these ranks in the embedding space. Experiments show SIGEM's superior accuracy in graph reconstruction, node classification, and link prediction across eight real-world datasets, outperforming thirteen state-of-the-art methods and demonstrating robustness against common drawbacks.
Executive Impact
SIGEM offers a groundbreaking approach to graph embedding, leveraging a new similarity measure, LINOW, to address critical limitations of existing methods. Its matrix-form computation significantly boosts speed and scalability, making it suitable for large-scale enterprise graphs. The method's superior performance in various graph-related tasks, including link prediction and node classification, translates directly to enhanced predictive analytics, improved anomaly detection, and more accurate recommendation systems for businesses. This innovation provides a robust, efficient, and highly accurate foundation for AI-driven insights in complex network data.

Graph Embedding
Graph Embedding
Graph embedding methods represent nodes in a graph as latent vectors in a low-dimensional space while preserving their semantic information and community structure [16, 37, 49, 55]. Diverse machine learning tasks such as graph reconstruction [16, 36, 57], link prediction [23, 49, 50], and node classification [45, 49, 50] utilize these latent vectors for graph inference and analysis. In this paper, we focus on single-vector embedding methods for unweighted and unsigned graphs that utilize only the graph topology in the embedding process.

Frequently Asked Questions
What is LINOW?
LINOW (LInk-based similarity measure utilizing NOdes' Weights) is a novel recursive similarity measure for graphs, applicable to both directed and undirected graphs. It considers recursive in-neighbor relationships to compute similarity scores, designed for efficiency and accuracy without approximation.
How does SIGEM address scalability?
SIGEM employs scalable variants of LINOW (LINOW-sn for single-node and LINOW-bn for batch-node computations) which provide linear memory complexities. This allows SIGEM to process large-scale graphs efficiently without losing accuracy, significantly improving upon naive LINOW's O(|V|²) memory demands.
What machine learning tasks does SIGEM excel in?
SIGEM consistently achieves the highest accuracy in graph reconstruction and node classification tasks. It also significantly outperforms other methods in most link prediction tasks. This broad effectiveness across core graph-related ML tasks makes it a versatile tool for enterprise AI.
