DRIFT: A Benchmark for Task-Free Continual Graph Learning with Continuous Distribution Shifts

arXiv:2605.12998v3 Announce Type: replace Abstract: Continual graph learning (CGL) aims to learn from dynamically evolving graphs while mitigating catastrophic forgetting. Existing CGL approaches typically adopt a task-based formulation, where the data stream is partitioned into a sequence of discrete tasks with pre-defined boundaries. However, such assumptions rarely hold in real-world environments, where data distributions evolve continuously and task identity is often unavailable. To better reflect realistic non-stationary environments, we revisit continual graph learning from a task-free p

Why this matters
Why now

The proliferation of dynamic, real-world data streams necessitates more robust and adaptable AI learning paradigms, moving beyond static, task-based approaches.

Why it’s important

This development addresses a fundamental limitation in AI's ability to operate effectively in complex, continuously evolving environments, crucial for real-world applications of machine learning.

What changes

The creation of a benchmark for task-free continual graph learning directly challenges conventional discrete-task assumptions, fostering research into more adaptive and realistic AI systems.
