A systematic literature review synthesized findings from 81 unique Online Continual Learning (OCL) approaches, analyzing over 1,000 features and identifying more than 500 components. This comprehensive overview provides a structured understanding of the current state of OCL research, detailing common strategies, architectures, datasets, and key challenges like catastrophic forgetting.

Key insights

  • Replay-based methods are the most prevalent strategy in Online Continual Learning (OCL), with Experience Replay being commonly used.
  • ResNet architectures are the most popular backbone (used in 61 of 81 surveyed approaches), and SGD is the dominant optimization technique.
  • Catastrophic forgetting remains the primary challenge in OCL, explicitly addressed by 44 of the analyzed approaches.
