LargeMonitor addresses a critical gap in online task-free continual learning by decoupling drift detection from the training process, thereby avoiding brittle threshold tuning and training-dependent interference. The framework leverages frozen large vision models for robust zero-shot drift detection and employs large multimodal models to diagnose the semantic causes of distribution shifts, such as novel class emergence or domain changes. This approach enables continuous learners to dynamically deploy shift-specific optimization strategies without modifying their core architecture, offering a more resilient solution for non-stationary data streams.
LargeMonitor: Monitoring Online Task-Free Continual Learning via Large Pretrained Models
arXiv:2606.09430v1 Announce Type: new Abstract: Online task-free continual learning (TFCL) requires intelligent agents to sequentially accumulate knowledge from an unbounded, non-stationary data stream under strict single-pass constraints and without any explicit task identifiers. Existing online TFCL paradigms primarily rely on parameter-efficient prompt tuning or dynamic structure expansion driven by training-coupled optimization dynamics, such as empirical loss fluctuations or evolving latent distances. As a result, these training-coupled solvers remain agnostic to the structural origins of distribution drift, mechanically enforcing a fixed strategy across fundamentally distinct streaming variations. To address this gap, we propose LargeMonitor, a framework that leverages large pretrained foundation models to autonomously orchestrate task-free continuous adaptation. Specifically, LargeMonitor introduces a decoupled detection module utilizing the frozen, stable representation space of large vision models (LVMs) to achieve robust, zero-shot drift detection without training-dependent interference or brittle threshold tuning. Upon a confirmed drift, the framework activates a context-aware diagnostic module driven by large multimodal models (LMMs) to interpret the precise semantic etiologies of the stream variation (e.g., novel class emergence vs. environmental domain shift). This dual-stage capability empowers the continuous learner to dynamically deploy adaptive and shift-specific optimization strategies. Extensive experiments across multiple TFCL settings and benchmarks demonstrate that LargeMonitor achieves precise, robust detection and diagnosis of complex data streams while consistently improving the performance of existing online TFCL algorithms.
