Minimalist Continual Learning Agent
This research introduces a novel continual learning agent designed to isolate representational dynamics. Unlike complex deep learning models, it operates with a minimal architecture, maintaining a persistent internal state without explicit regularization, replay buffers, or forgetting mechanisms. Its purpose is to observe how representations accumulate, stabilize, and adapt under continuous exposure to new information in a transparent, interpretable manner.
The agent processes a growing corpus of textual data, incrementally updating a state vector. This design reflects real-world constraints where retraining or resets are infeasible, focusing on long-term knowledge accumulation rather than short-term task performance.
Quantifying Internal State Evolution
The agent's internal state is a fixed-dimensional numerical vector, where each dimension corresponds to a unique token from the observed vocabulary, and its value reflects the token's aggregated frequency. This vector grows monotonically as new experience is accumulated.
To quantify representational change, cosine similarity is used between successive normalized state vectors. This provides a stable, scale-invariant measure of directional alignment, independent of corpus size. High similarity indicates stability, while decreases signal periods of plasticity. A formal Representational Stability metric, S(t1, t2), is defined as the average cosine similarity over a given interval.
Observed Stability-Plasticity Trade-offs
Longitudinal experiments across 8 runs reveal a clear learning trajectory: an initial plastic regime (similarity 0.0 to 0.98), transitioning to a stable regime (up to 0.99) under consistent input. A deliberate semantic perturbation on Day 5, introducing disjoint vocabulary, caused a bounded decrease in similarity to 0.8957.
Crucially, the representation subsequently recovered and re-stabilized to 0.998 under continued coherent input. This demonstrates that stability and adaptability are not mutually exclusive and can emerge naturally without engineered mechanisms, showing the agent can assimilate novel information without catastrophic forgetting.
Building Reliable, Long-Lived AI Systems
This work suggests that meaningful learning dynamics, including stability and controlled adaptation, can emerge from fundamental principles of persistent state, incremental accumulation, and self-comparison, even without complex architectures or task-driven optimization. This challenges traditional evaluation metrics focused solely on performance.
While the agent is intentionally minimal (token-frequency representation, no compression, no interaction), it provides a transparent baseline. Future work could explore structured representations, dimensionality reduction, and integrate insights from robotics, neuroscience, and physics to build more robust, interpretable, and scalable continual learning systems for diverse enterprise applications.
